The high number of grapevine (Vitis vinifera L.) cultivars grown world-wide are described and identified according to detailed morphological and morphometric descriptor lists. The grapevine leaf is of utmost importance in characterization, despite its traits being very sensitive to environmental factors. In this study, the effect of irrigation/drought stress on the individual leaf morphology and morphometry of the ‘Hárslevelű’ grapevine (Vitis vinifera L.) cultivar was examined. To verify the effect of the applied irrigation methods (drip and subsoil irrigation) on the plant’s water status, water potential measurements were carried out during the 2022 season. The effect of the applied treatments on the vegetative growth was evaluated according to point quadrat and a multichannel LiDAR analysis in order to describe the width of the canopy area, row volume, and area coverage index. The individual leaf morphology was assessed via traditional morphometry and colorimetry. Our results showed that rainfed plants had a significantly lower stem ψ compared to the drip- and subsoil-irrigated plants at all examined dates. The point quadrat results indicate that the leaf layer number was significantly (p < 0.05) influenced by the position, while the treatment showed no effect on the leaf layer number. The leaf colorimetry showed a difference among the samples, as significant alterations were found in 28 out of the 32 examined color properties. Within the traditional morphometric analysis, 54 traits were evaluated, and 14 of the traits were significantly altered due to the different water management systems.
根据详细的形态和形态计量描述表,对世界各地种植的大量葡萄(Vitis vinifera L.)栽培品种进行了描述和鉴定。尽管葡萄叶片的性状对环境因素非常敏感,但它在特征描述中却至关重要。本研究考察了灌溉/干旱胁迫对'Hárslevelű'葡萄(Vitis vinifera L.)单个叶片形态和形态计量的影响。为了验证灌溉方法(滴灌和底土灌溉)对植物水分状况的影响,在 2022 年的季节进行了水势测量。通过点四分法和多通道激光雷达分析评估了施用处理对植物生长的影响,以描述冠层面积宽度、行体积和面积覆盖指数。通过传统的形态测量法和比色法对单叶形态进行了评估。结果表明,在所有考察日期,雨浇植物的茎ψ都明显低于滴灌和底土灌溉植物。点四分法的结果表明,叶层数量受位置的影响很大(p < 0.05),而处理对叶层数量没有影响。叶片色度分析表明,不同样本之间存在差异,在 32 个检测的颜色特性中,28 个有明显变化。在传统的形态分析中,对 54 个性状进行了评估,其中 14 个性状因不同的水管理制度而发生了显著变化。

The high biological activity of cultivated and wild purslane offers broad possibilities for utilizing this plant in medicine and human nutrition. To assess the prospects of obtaining new functional food products based on the wild form of P. oleracea L., foliar biofortification of this species with sodium selenate (VI) was carried out, and the changes in leaf and seed biochemical characteristics were investigated. Selenium significantly enhanced plant yield, photosynthetic pigments and the ascorbic acid content, and showed a tendency to seed productivity increase. The application of selenium augmented quinic acid content in leaves by 1.7 times but did not affect the oxalic acid content. Oxalic acid prevailed in wild purslane and quinic acid in cultivated purslane (cv. Makovey). Seed oil in Se-enriched purslane was characterized by a two-fold decrease in saturated fatty acids and squalene and 2.3-fold decrease in malonic dialdehyde content, along with a 1.4-fold increase in ascorbic acid. Selenium supplementation resulted in an increase in total lipids and mono- and di-unsaturated fatty acids and did not affect the concentration of ω-3 fatty acids and sterol accumulation. Among the identified sterols, only the minor ones (fucosterol, 7-stigmasterol and ∆7-avenosterol) showed a slight decrease upon Se supply. Compared to seeds of cv. Makovey, wild purslane seeds had higher levels of antioxidant activity by a factor of 2 and of polyphenols by a factor of 3.2 but did not differ significantly in oil fatty acid composition. The results indicate the importance of wild purslane leaves/seeds both fortified and not fortified with Se in human nutrition and medicine.
栽培和野生马齿苋的高生物活性为将这种植物用于医药和人类营养提供了广泛的可能性。为了评估基于野生马齿苋获得新功能食品的前景,研究人员用硒酸钠(VI)对该物种进行了叶面生物强化,并调查了叶片和种子生化特性的变化。硒能明显提高植物产量、光合色素和抗坏血酸含量,并有提高种子产量的趋势。施硒使叶片中的喹酸含量增加了 1.7 倍,但对草酸含量没有影响。野生马齿苋以草酸为主,而栽培马齿苋(Makovey 变种)则以奎宁酸为主。富硒马齿苋籽油的特点是饱和脂肪酸和角鲨烯含量减少两倍,丙二醛含量减少 2.3 倍,抗坏血酸含量增加 1.4 倍。补硒会导致总脂质、单不饱和脂肪酸和双不饱和脂肪酸的增加,但不会影响ω-3 脂肪酸的浓度和固醇的积累。在已确定的甾醇中,只有次要甾醇(褐藻甾醇、7-赤霉醇和 ∆7-avenosterol )在供应 Se 后略有减少。与 Cv.相比,野生马齿苋种子的抗氧化活性高出 2 倍,多酚含量高出 3.2 倍,但油脂肪酸组成没有显著差异。结果表明,野生马齿苋叶片/种子在人类营养和医药方面具有重要意义,无论是强化还是未强化 Se。

This study evaluated the effect of salicylic acid (SA) application on yield, fruit quality, and post-harvest storage in Prunus avium subjected to deficit irrigation (DI). A field experiment with six-year-old P. avium cv. Lapins was performed under two water treatments: irrigation at 100% of crop evapotranspiration (ETc) [full irrigation (FI)] and irrigation at 60% ETc from the second fruit phase to harvest time (DI). A single 0.5 mM SA was applied to both water treatments at fruit color change. At harvest time, fruits were collected to determine yield, fruit quality, and quality during post-harvest storage (0, 10, 20, and 30 days). The DI reduced fruit yield (11%), fruit weight (8%), and caliber (6%) and increased firmness (7%) and total soluble solids (TSS) (5%) in P. avium compared with FI plants at harvest time. Our study showed that SA application recovered fruit yield (9%), fruit weight (5%), and caliber (4%), improving TSS in DI plants at day 0. Interestingly, SA application significantly reduced P. avium fruit cracking (78% in FI and 82% in DI). Fruit weight was reduced in all treatments, mainly decreasing by 14% in FI and 13% in DI plants at day 30 of post-harvest storage. Fruit weight did not change during post-harvest storage with SA, except on day 30, where a slight reduction was observed. TSS showed no significant differences during post-harvest storage for all treatments. Therefore, SA could be an interesting tool to mitigate the impact of DI on the yield and fruit quality of P. avium and to reduce fruit cracking and prolong fruit quality during post-harvest storage.
本研究评估了施用水杨酸(SA)对亏缺灌溉(DI)条件下的杨梅产量、果实质量和采后贮藏的影响。对 6 年树龄的 Lapins 栽培品种进行了田间试验,试验采用了两种水处理方法:100% 的作物蒸散量(ETc)灌溉[全灌溉(FI)]和从第二果实期到采收期 60% 的 ETc 灌溉(DI)。在果实转色时,两种水处理均施用一次 0.5 毫摩尔的 SA。采收时,收集果实以确定产量、果实质量和采后贮藏(0、10、20 和 30 天)期间的质量。与 FI 植物相比,DI 在收获时降低了 P. avium 的果实产量(11%)、果实重量(8%)和口径(6%),提高了坚硬度(7%)和总可溶性固形物(TSS)(5%)。我们的研究表明,施用南美蔗糖能恢复 DI 植株第 0 天的果实产量(9%)、果实重量(5%)和口径(4%),并提高总可溶性固形物(TSS)。所有处理的果实重量都有所下降,在采后贮藏的第 30 天,FI 和 DI 植株的果实重量分别下降了 14% 和 13%。使用 SA 的采后贮藏期间,果实重量没有变化,只有第 30 天略有下降。在采后贮藏期间,所有处理的 TSS 均无明显差异。因此,在采后贮藏期间,SA 可以作为一种有趣的工具来减轻 DI 对 P. avium 产量和果实质量的影响,并减少果实开裂和延长果实质量。

Landraces are considered a crucial component of biodiversity conservation, serving as a reservoir of genetic diversity. Consequently, the collection, cultivation, and detailed characterization of such landraces constitute an inherent aspect of the world’s natural resource heritage. This effort holds promise for the development of elite varieties capable of thriving amidst continuous global climate fluctuations. In this context, we conducted a comprehensive assessment of the main agronomic attributes, physico-chemical properties, and functional quality traits of the major hot pepper landraces adapted to diverse climatic conditions in Tunisia. These landraces include ‘Dhirat’, ‘Semmane’, ‘Beldi’, ‘Nabeul’, ‘Jerid’, ‘Mahdia’, ‘Cayenne’, ‘Kairouan’, and ‘Baklouti’. Most of the pepper landraces exhibited satisfactory yields, ranging from 1163.25 to 1841.67 g plant−1 in ‘Jerid’ and ‘Kairouan’, respectively, indicating robust productivity, especially under prevailing climatic changes and high temperatures during both growing cycles. The levels of antioxidants comprising capsaicinoids, carotenoids, phenolics, and tocopherols, as well as radical scavenging activity, emerged as key discriminating factors among pungent pepper landraces. Irrespective of genotype, capsaicin and dihydrocapsaicin constituted the major capsaicinoids, accounting for 44–91% of the total capsaicinoids content. Total capsaicinoids ranged from 1.81 µg g−1 fw to 193.71 µg g−1 fw, with ‘Baklouti’ and ‘Jerid’ identified as the most pungent landraces. Total carotenoids ranged from 45.94 µg g−1 fw to 174.52 µg g−1 fw, with ‘Semmane’ and ‘Jerid’ exhibiting the highest levels. Considerable variation was observed in β-carotene content, spanning from 3% to 24% of the total carotenoids. α-Tocopherol content ranged from 19.03 µg g−1 fw in ‘Kairouan’ to 30.93 µg g−1 fw in ‘Beldi’, exerting a notable influence on the overall tocopherol content. Conversely, the β- and γ-tocopherol isomers were detected at very low concentrations. The total vitamin C content ranged from 132 mg 100g−1 fw in ‘Mahdia’ to 200 mg 100 g−1 fw in ‘Nabeul’, indicating relatively low genetic variability. However, large variability was detected in total phenolics content, ranging from 168.58 mg GAE kg−1 fw in ‘Beldi’ to 302.98 mg GAE kg−1 fw in ‘Cayenne’. Landraces such as ‘Dhirat’, ‘Nabeul’, ‘Semmane’, ‘Kairouan’, ‘Cayenne’, and ‘Mahdia’ appear suitable for both fresh consumption and processing, owing to their favorable average fruit weight, soluble solids content, and bioactive content. Among the pepper landraces tested, ‘Cayenne’ achieved the highest value of radical scavenging activity in both hydrophilic and lipophilic fractions (RSAHF and RSALF), with variations ranging from 59% to 120% for RSAHF and from 4% to 63% for RSALF. This study aims to preserve and enhance the value of local genetic resources and contribute to identify desirable traits for incorporation into breeding programs to develop high-quality, high-yield
陆生品系被认为是生物多样性保护的重要组成部分,是遗传多样性的宝库。因此,收集、培育和详细描述这些陆生品种是世界自然资源遗产的一个固有方面。这项工作有望培育出能够在全球持续气候波动中茁壮成长的优良品种。在此背景下,我们对适应突尼斯不同气候条件的主要辣椒陆生品系的主要农艺属性、物理化学特性和功能品质特征进行了全面评估。这些品种包括 "Dhirat"、"Semmane"、"Beldi"、"Nabeul"、"Jerid"、"Mahdia"、"Cayenne"、"Kairouan "和 "Baklouti"。大多数辣椒地方品种都表现出令人满意的产量,'Jerid'和'Kairouan'的单株产量分别为 1163.25 克至 1841.67 克,这表明它们具有很强的生产力,尤其是在两个生长周期内气候普遍变化和温度较高的情况下。辣椒素、类胡萝卜素、酚类和生育酚等抗氧化剂的含量以及自由基清除活性是区分不同辣味胡椒品种的关键因素。无论基因型如何,辣椒素和二氢辣椒素都是主要的辣椒碱,占辣椒碱总含量的 44-91%。辣椒素总量从 1.81 µg g-1 fw 到 193.71 µg g-1 fw 不等,其中 "Baklouti "和 "Jerid "被认定为刺激性最强的陆地品种。类胡萝卜素总量从 45.94 µg g-1 fw 到 174.52 µg g-1 fw 不等,其中'Semmane'和'Jerid'的含量最高。α-生育酚含量从'凯鲁万'的 19.03 微克/克(重量)到'贝尔迪'的 30.93 微克/克(重量)不等,对整个生育酚含量有显著影响。相反,β- 和 γ-生育酚异构体的含量非常低。总维生素 C 含量从 "Mahdia "的 132 毫克 100 克-1(重量比)到 "Nabeul "的 200 毫克 100 克-1(重量比)不等,表明遗传变异相对较低。然而,总酚含量的变异较大,从'Beldi'的 168.58 毫克 GAE kg-1 fw 到'Cayenne'的 302.98 毫克 GAE kg-1 fw。Dhirat"、"Nabeul"、"Semmane"、"Kairouan"、"Cayenne "和 "Mahdia "等品种由于其平均果重、可溶性固形物含量和生物活性含量较高,似乎既适合新鲜食用,也适合加工。在测试的辣椒品种中,"Cayenne "在亲水和亲油部分(RSAHF 和 RSALF)的自由基清除活性值最高,RSAHF 的变化范围为 59% 至 120%,RSALF 的变化范围为 4% 至 63%。这项研究旨在保护和提高当地遗传资源的价值,并有助于确定理想的性状,以便将其纳入育种计划,培育出优质、高产的陆地品系和精英品系。

Considerable variation was observed in β-carotene content, spanning from 3% to 24% of the total carotenoids. α-Tocopherol content ranged from 19.03 µg g−1 fw in ‘Kairouan’ to 30.93 µg g−1 fw in ‘Beldi’, exerting a notable influence on the overall tocopherol content. Conversely, the β- and γ-tocopherol isomers were detected at very low concentrations. The total vitamin C content ranged from 132 mg 100g−1 fw in ‘Mahdia’ to 200 mg 100 g−1 fw in ‘Nabeul’, indicating relatively low genetic variability. However, large variability was detected in total phenolics content, ranging from 168.58 mg GAE kg−1 fw in ‘Beldi’ to 302.98 mg GAE kg−1 fw in ‘Cayenne’. Landraces such as ‘Dhirat’, ‘Nabeul’, ‘Semmane’, ‘Kairouan’, ‘Cayenne’, and ‘Mahdia’ appear suitable for both fresh consumption and processing, owing to their favorable average fruit weight, soluble solids content, and bioactive content. Among the pepper landraces tested, ‘Cayenne’ achieved the highest value of radical scavenging activity in both hydrophilic and lipophilic fractions (RSAHF and RSALF), with variations ranging from 59% to 120% for RSAHF and from 4% to 63% for RSALF.

Flourensia cernua and Jatropha dioica are non-timber forest species that grow in the desert regions of northern Mexico. Currently, they are recognized as a viable alternative to traditional remedies used to address certain ailments. However, the low yields of bioactive compounds obtained propitiate the use of more effective extraction techniques such as ultrasound-assisted extraction (UAE) in combination with statistical models such as Taguchi to maximize the yields of bioactive compounds. The objective of the research was to determine the optimal conditions for maximizing the yields of purified polyphenolic compounds from F. cernua and J. dioica using the Taguchi statistical model. In addition, we evaluated the total flavonoid content, antioxidant activity (ABTS•+, FRAP, and OH• hydroxyl radical inhibition), and the in vitro evaluation of α-amylase inhibition and ex vivo hemolysis inhibition. Furthermore, a functional group analysis was conducted using FTIR. The optimization process revealed that the maximum yields of bioactive compounds for F. cernua and J. dioica were achieved with a particle size of 0.25 mm and 0.30 mm, temperatures of 60 °C for both, a water–ethanol concentration of 50% for both, and extraction times of 30 min and 5 min, respectively. The matrix bioactive compounds obtained contain flavonoid-type phenolic compounds, which exhibit properties such as inhibiting free radicals and acting as reducing agents; inhibiting α-amylase activity, which is involved in carbohydrate metabolism; and protecting red blood cells from damage by reactive oxygen species. Finally, the FTIR analysis allowed for the identification of functional groups associated with the polyphenolic compounds (O–H, C–H, C–C, C=O). These results suggest that both non-timber forest species are a rich source of bioactive compounds with potential for application in the agri-food and pharmaceutical industries However, it is necessary to carry out compound identification as well as toxicity analyses to guarantee the safety of these bioactive compounds.
仙人掌属(Flourensia cernua)和麻风树属(Jatropha dioica)是生长在墨西哥北部沙漠地区的非木材森林物种。目前,它们被认为是治疗某些疾病的传统疗法的可行替代品。然而,由于生物活性化合物的产量较低,因此需要使用更有效的萃取技术,如超声波辅助萃取(UAE),并结合田口等统计模型,以最大限度地提高生物活性化合物的产量。本研究的目的是利用田口统计模型确定从 F. cernua 和 J. dioica 提取纯化多酚化合物产量最大化的最佳条件。此外,我们还评估了总黄酮含量、抗氧化活性(ABTS-+、FRAP 和 OH- 羟自由基抑制作用)、体外α-淀粉酶抑制作用和体内外溶血抑制作用。此外,还利用傅立叶变换红外光谱进行了官能团分析。优化过程表明,在粒径分别为 0.25 毫米和 0.30 毫米、温度均为 60 ℃、水乙醇浓度均为 50%、提取时间分别为 30 分钟和 5 分钟的条件下,蕨麻和鸦胆子的生物活性化合物产量最高。获得的基质生物活性化合物含有黄酮类酚化合物,具有抑制自由基和作为还原剂、抑制参与碳水化合物代谢的α-淀粉酶活性、保护红细胞免受活性氧损伤等特性。最后,通过傅立叶变换红外光谱分析,可以确定与多酚类化合物相关的官能团(O-H、C-H、C-C、C=O)。这些结果表明,这两种非木材森林物种都是生物活性化合物的丰富来源,具有应用于农业食品和制药业的潜力,但有必要进行化合物鉴定和毒性分析,以确保这些生物活性化合物的安全性。

The sclerotia of Wolfiporia hoelen (Fr.) Y.C. Dai & V. Papp is an important traditional Chinese medicine with diverse pharmacological properties. This study utilized a combination of PacBio Long-Read Sequencing, Illumina Short-Read Sequencing, and Hi-C Sequencing to generate a high-quality chromosome-level genome assembly of a W. hoelen strain Minling A5. There were 112 contigs in the genome, with 62.95 Mb in total length and 4.21 Mb in length for the contig N50. The average GC content was 51.89%. Based on Hi-C data, we corrected the CCS data and scaffolded them into 14 pseudo-chromosomes. The genome contained 44.37% repetitive sequences and 12,670 protein-coding genes, 86.53% (10,963) of which could be functionally annotated in at least one of the KOG, GO, Pfam, Swissprot, TrEMBL, NR, and KEGG databases. In addition, 240 transfer RNAs, 97 ribosomal RNAs, and 103 other non-coding RNAs were identified in the W. hoelen genome. A total of 755 pseudogenes were also identified, with an average length of 2665.51 bp. Further, there were 398, 100, 2837, 519, and 2068 genes annotated by CAZymes, TCDB, PHI, P450, and DFVF databases, respectively. One notable attribute of W. hoelen is its capacity to thrive in a substrate of fresh pine sawdust. Through an analysis of the growth on various pure wood sawdust culture media, we found that the growth of W. hoelen and Sparassis latifolia on pine sawdust was similar to that on broad-leaved wood sawdust, while the growth of Pleurotus ostreatus, P. eryngii, and Cyclocybe aegerita was slower than that on broad-leaved wood sawdust. By the functional annotation analysis of orthogroups in these five mushroom-forming fungi, it was determined that 645 orthogroups were specifically common in W. hoelen and S. latifolia. The genes in these specific orthogroups were significantly enriched in 12 pathways, including steroid biosynthesis, biosynthesis of antibiotics, and tyrosine metabolism. The high-quality genome and comparative genome analysis results significantly contribute to advancing our foundational knowledge of W. hoelen biology, while also offering valuable insights for the development of innovative biotechnological approaches aimed at enhancing the efficient and sustainable utilization of Pinus.
枸杞子(Wolfiporia hoelen (Fr.) Y.C. Dai & V. Papp)是一种重要的传统中药,具有多种药理作用。本研究利用 PacBio 长读取测序、Illumina 短读取测序和 Hi-C 测序相结合的方法,生成了枸杞菌株闽灵 A5 的高质量染色体组基因组。基因组中有 112 个等位基因,总长度为 62.95 Mb,等位基因 N50 长度为 4.21 Mb。平均 GC 含量为 51.89%。根据 Hi-C 数据,我们对 CCS 数据进行了校正,并将其支架化为 14 个假染色体。该基因组包含 44.37% 的重复序列和 12,670 个编码蛋白质的基因,其中 86.53% 的基因(10,963 个)可在 KOG、GO、Pfam、Swissprot、TrEMBL、NR 和 KEGG 数据库中的至少一个数据库中进行功能注释。此外,在 W. hoelen 基因组中还发现了 240 个转移 RNA、97 个核糖体 RNA 和 103 个其他非编码 RNA。还发现了 755 个假基因,平均长度为 2665.51 bp。此外,CAZymes、TCDB、PHI、P450 和 DFVF 数据库分别注释了 398、100、2837、519 和 2068 个基因。W. hoelen 的一个显著特征是它能在新鲜松木锯屑的基质中生长。通过分析其在各种纯木锯屑培养基上的生长情况,我们发现 W. hoelen 和 Sparassis latifolia 在松木锯屑上的生长情况与在阔叶木锯屑上的生长情况相似,而 Pleurotus ostreatus、P. eryngii 和 Cyclocybe aegerita 在阔叶木锯屑上的生长速度则较慢。通过对这五种蘑菇形成真菌的正交组进行功能注释分析,确定了 645 个正交组在 W. hoelen 和 S. latifolia 中特别常见。这些特定直向群中的基因在 12 个途径中明显富集,包括类固醇生物合成、抗生素生物合成和酪氨酸代谢。高质量的基因组和比较基因组分析结果极大地促进了我们对松柏生物学基础知识的了解,同时也为开发创新生物技术方法提供了宝贵的见解,这些方法旨在提高松柏的高效和可持续利用。

Ploidy identification is a basic method for determining germplasm resources and for breeding new varieties of oil-seed camellia. In this study, flow cytometry and K-mer analysis were used to identify the ploidy of oil-seed camellia germplasms. To determine the best tissue organ type, lysis time, and dyeing time, evaluation indices such as the presence of a clear main peak, the ease of sampling, and the coefficient of variation were used. A technique was established, and the ploidies of different oil-seed camellia germplasms were identified. The results showed that pollen was the best material and that using a 400 mL PI lysis solution for 10 min lysis, followed by dyeing with a 1600 mL DAPI dyeing solution for 10 min, was the most suitable technique. According to the peak value of the control diploid Camellia azalea, 15 samples were estimated to be diploid, 24 samples were tetraploid, 18 samples were hexaploid, and 13 samples were octoploid. In addition, the K-mer analysis results showed that among the five samples, CK, C051, and C047 were diploid, while C037 and C043 were tetraploid, results that are consistent with the results of the flow cytometry identification. This study is therefore valuable for the polyploid selection and use of different ploidy germplasm resources for the cross breeding of oil-seed camellia.
倍性鉴定是确定油茶种质资源和培育新品种的基本方法。本研究采用流式细胞仪和 K-mer分析来鉴定油茶种质的倍性。为确定最佳组织器官类型、裂解时间和染色时间,采用了主峰是否清晰、取样难易程度和变异系数等评价指标。建立了一种技术,并确定了不同油茶种质的倍性。结果表明,花粉是最佳材料,使用 400 mL PI 溶液裂解 10 分钟,然后用 1600 mL DAPI 染色液染色 10 分钟是最合适的技术。根据对照二倍体山茶杜鹃的峰值,推测 15 个样品为二倍体,24 个样品为四倍体,18 个样品为六倍体,13 个样品为八倍体。此外,K-聚合体分析结果显示,5 个样品中,CK、C051 和 C047 为二倍体,C037 和 C043 为四倍体,这些结果与流式细胞仪鉴定结果一致。因此,这项研究对于油茶多倍体选育和利用不同倍性的种质资源进行油茶杂交育种具有重要价值。

Sewage sludge can be used as an organic amendment as long as it is ensured that there is no risk of environmental contamination or risk to public health. In this study, sewage sludge from two wastewater treatment plants (WWTPs) subjected to two disinfection and stabilization treatments [40% (mass/mass), calcium oxide, and calcium hydroxide] and their respective untreated sewage sludge were used. Three control treatments were also added: conventional farmyard manure (FYM), a nitrogen (N) mineral fertilizer (ammonium nitrate 34.5% N) applied at a rate of 50 kg N ha−1 (N50) (the same rate of all organic amendments), and an unfertilized control (N0), totaling nine treatments. Lettuce (Lactuca sativa L.) was cultivated in pots for two growing cycles. The dry matter yield (DMY) was higher in the N50 treatment (13.5 and 10.6 g plant−1 in the first and second growing cycles, respectively), followed by sewage sludge (10.8 to 12.4 and 8.4 to 8.7 g plant−1), FYM (8.5 and 7.2 g plant−1), and the control (7.7 and 6.0 g plant−1). The DMY was related to the N provided by the different treatments, assessed by the N and nitrate concentrations in tissues, N uptake, and apparent N recovery (ANR). Sewage sludge, due to its high N concentration and low carbon (C)/N ratio, mineralized rapidly, providing a significant amount of N to plants, as well as other nutrients, such as phosphorus (P) and boron (B). FYM, with a higher C/N ratio, provided less N to plants, also due to the short duration of the lettuce growing cycle. Alkalized sewage sludge increased soil pH and calcium (Ca) availability for plants. Fertilizer treatments minimally influenced cationic micronutrients. Heavy metals in the initial sewage sludge were below the threshold values established in international legislation, and the levels in soil and lettuce tissues were generally not higher than those in other treatments. Both of the sewage sludges used in this study showed high fertilizing value and very reactive behavior, making nutrients available much more quickly than FYM. This information is relevant to consider in defining their agricultural use.
只要确保不会造成环境污染或危害公众健康,污水污泥就可以用作有机添加剂。在这项研究中,使用了来自两家污水处理厂的经过两种消毒和稳定化处理[40%(质量/质量)、氧化钙和氢氧化钙]的污水污泥及其各自未经处理的污水污泥。此外,还添加了三种对照处理:常规农家肥(FYM)、氮(N)矿物肥料(硝酸铵,氮含量为 34.5%),施肥量为 50 千克/公顷(N50)(与所有有机添加剂的施肥量相同),以及未施肥对照(N0),共计九种处理。生菜(Lactuca sativa L.)在花盆中栽培了两个生长周期。N50 处理的干物质产量(DMY)较高(第一和第二个生长周期分别为 13.5 和 10.6 g plant-1),其次是污水污泥(10.8 至 12.4 和 8.4 至 8.7 g plant-1)、生石灰(8.5 和 7.2 g plant-1)以及对照(7.7 和 6.0 g plant-1)。DMY 与不同处理提供的氮有关,通过组织中的氮和硝酸盐浓度、氮吸收量和表观氮回收率(ANR)进行评估。污水污泥的氮浓度高,碳(C)/氮比率低,因此矿化速度快,为植物提供了大量的氮以及磷(P)和硼(B)等其他养分。C/N比值较高的堆肥为植物提供的氮较少,这也是由于莴苣的生长周期较短。碱化的污水污泥提高了土壤的 pH 值和植物对钙(Ca)的利用率。肥料处理对阳离子微量营养元素的影响很小。初始污水污泥中的重金属含量低于国际法规规定的阈值,土壤和莴苣组织中的重金属含量一般不高于其他处理方法。本研究中使用的两种污水污泥都具有很高的肥料价值和很强的反应性,使养分的利用速度远高于 FYM。在确定它们的农业用途时,需要考虑这些信息。

Climate change is currently the greatest threat to the environment as we know it today. The present study aimed to highlight the changes in the main climatic elements during the last five decades (1971–2020) in northeastern Romania (Copou-Iaşi wine-growing center) and their impact on grape quality, as part of precision viticulture strategies and efficient management of grapevine plantations. Data analysis revealed a constant and significant increase in the average air temperature in the last 50 years (+1.70 °C), more pronounced in the last 10 years (+0.61 °C), with a number of days with extreme temperatures (>30 °C) of over 3.5-fold higher, in parallel with a fluctuating precipitation regime. The increase in average temperatures in the last 40 years was highly correlated with the advancement of the grape harvest date (up to 12 days), a significant increase in Vitis vinifera L. white grape sugar concentration (+15–25 g/L), and a drastic decrease in total acidity (−2.0–3.5 g/L tartaric acid). The significant increase in the values of the bioclimatic indices require the reclassification of the wine-growing area in higher classes of favorability, raising the opportunity to grow cultivars that are more suited to warmer climates, ensuring the efficiency of the plantation, and meeting current consumer expectations.
气候变化是当今环境面临的最大威胁。本研究旨在强调罗马尼亚东北部(科普伊亚希葡萄种植中心)过去五十年(1971-2020 年)主要气候要素的变化及其对葡萄质量的影响,作为精准葡萄栽培战略和葡萄种植园高效管理的一部分。数据分析显示,在过去的 50 年中,平均气温持续显著上升(+1.70 °C),在过去的 10 年中更为明显(+0.61 °C),极端气温(>30 °C)的天数增加了 3.5 倍以上,与此同时,降水量也在波动。过去 40 年平均气温的升高与葡萄采摘期的提前(最多 12 天)、葡萄白糖浓度的显著增加(+15-25 克/升)和总酸度的急剧下降(-2.0-3.5 克/升酒石酸)高度相关。生物气候指数值的大幅上升要求将葡萄种植区重新划分为更高的有利等级,从而有机会种植更适合温暖气候的品种,确保种植园的效率,满足当前消费者的期望。
