The aim of this study is to explore the relationship between soil nutrients and berry quality for the wine grape Vitis vinifera cv. Cabernet Franc in the eastern foothills of the Helan Mountains, and subsequently to optimize soil nutrient conditions for optimal berry quality, thus providing guidance for vineyard soil management. Based on the basic data on soil nutrients and berry quality indicators, a partial least squares regression method was used to screen for major soil nutrient factors affecting the grape quality index. Then, the selected soil nutrient factors were taken as independent variables and the corresponding grape quality indicators were taken as dependent variables and a multilinear regression equation was formulated by the method of multivariate linear regression. Finally, the optimal solution for fruit quality and soil nutrients was solved using linear programming equations. The results showed that there was a lack of total nitrogen, organic matter, nitrate nitrogen, ammonium nitrogen, and available phosphorus in the soil nutrients, and an alkaline soil. There is a significant positive correlation between some soil nutrient indices, and there is also a multivariate linearity problem. Among all berry quality indices, titratable acid, tannin, and anthocyanin were negatively correlated with eleven and ten soil indices, respectively, while other berry quality indices were positively correlated with most soil nutrient indices. The optimal parameters for grape quality were determined using the method of linear programming equations, and the corresponding soil nutrient indicators content were defined.

Pleurotus cornucopiae cap color is an important commercial trait. The roles of non-coding RNA molecules (ncRNAs) in fungal fruiting body color formation are unclear. Whole-transcriptome analyses were performed, identifying messenger RNA (mRNA) and ncRNA (including long stranded non-coding RNA (lncRNA), micro RNA-like (milRNA), and circular RNA (circRNA)) molecules in three P. cornucopiae strains with different cap colors (grayish-black, grayish-white, and white), to investigate their roles in cap color formation. Differentially expressed mRNAs (n = 3604), lncRNAs (n = 520), milRNAs (n = 56), and circRNAs (n = 20) were identified among the three different color strains. Differentially expressed mRNAs and ncRNAs target genes were mainly involved in tyrosine, arachidonic acid, and histidine metabolism, plus other pathways potentially important in color formation. A competitive endogenous RNA (ceRNA) network and three mRNA and ncRNA co-expression networks were constructed, revealing relationships contributing to cap color formation, involving genes with roles in protein phosphorylation, and phenylalanine, tyrosine, and tryptophan biosynthesis. qRT-PCR analysis confirmed that mRNA and ncRNA levels were related to P. cornucopiae color. These regulatory networks may be crucial in P. cornucopiae color formation. Our data provide a new perspective to support further study of the mechanisms underlying P. cornucopiae color formation.

Fifteen transgenic shoot clones (TS A-TS O) regenerated from Hypericum perforatum hairy roots were evaluated for growth characteristics, phenylpropanoid, and naphthodianthrone production, as well as non-enzymatic and enzymatic antioxidant status. Transgenic shoots displayed higher biomass production and non-altered phenotypes compared to control shoots. Phenylpropanoid production in TS was not related to phenylalanine ammonia lyase activity indicating that alternative enzymes could be involved in the regulation of phenylpropanoid/flavonoid biosynthesis. The positive correlation between phenylpropanoids (phenolic acids, flavonoids, flavan-3-ols, tannins) and non-enzymatic antioxidant assays suggested that these compounds are the main contributors to the redox state and radical scavenging properties of TS clones. More importantly, enhanced naphthodianthrone production (hypericin, pseudohypericin and protopseudohypericin) in TS was associated with the number of leaf dark glands. Concerning the enzymatic antioxidant status of TS, guaiacol peroxidase was shown as the main enzyme that turns down H2O2 levels, while the upregulation of superoxide dismutase coincided with decreased O2•− production. The efficiency of antioxidant enzymes for O2•− and H2O2 neutralization decreased the level of MDA and consequently delayed lipid peroxidation in TS clones. Altogether, H. perforatum transgenic shoots could be proposed as a prospective biotechnological system for scale-up production of naphthodianthrones and phenylpropanoids with antioxidant properties.

The development and improvement of molecular biology methods have led to the creation of new technologies that make it possible to modify plant genomes by transferring and integrating into the genomes’ heterologous genes from various expression systems (genetic engineering), as well as inducing knockouts of one or more target genes of interest (genomic editing). The development of genome-editing methods is a new milestone in the development of modern breeding methods and certainly relies on the knowledge and technologies developed for transgenesis. This review will discuss issues related to the advantages and disadvantages of both technologies for improving the economically valuable traits of important crops.

Posidonia oceanica, a Mediterranean Sea seagrass, generates significant litter debris in coastal regions, adversely affecting tourism. To manage this debris, we explored two strategies: (i) promoting in situ decomposition by introducing ligninolytic microbes from forest microbiomes and (ii) utilizing P. oceanica debris as a substrate for ornamental and horticultural species. To achieve this goal, we conducted a one-year experiment using litter bags in mesocosms that simulate in situ conditions, evaluating the second strategy with different application rates (10%, 30%, 50%, and 100%) of fresh and decomposed P. oceanica debris mixed with peat or soil, with or without mineral fertilizer. The results revealed the resistance of P. oceanica necromass to decomposition; in fact, the introduction of forest microbiomes led to a major decomposition rate, albeit with constrained practical applicability. Utilizing P. oceanica debris as a substrate without fertilizer resulted in a modest growth response relative to the application rate, particularly accentuated in horticultural species compared to ornamental ones. Mineral fertilizer alleviated adverse effects at lower application rates; however, a notable decline in growth was observed at the 100% application rate. At application rates of 10% and 30%, certain crops demonstrated improved growth compared to the control. In summary, our study suggests the potential use of raw P. oceanica debris as a growth substrate within the 10% to 50% dosage range.

This paper aims to analyze comprehensively the climate exposure, sensitivity, perception, adaptive capacity, vulnerability, and resilience of the Hungarian agricultural sector, particularly focusing on fruit, vegetable, and grape producers. Four distinct Hungarian case studies were examined, representing different regions with diverse environmental and socioeconomic conditions. The research combined quantitative and qualitative methods, including statistical and GIS analysis of climate, agricultural, and socioeconomic data, as well as field research and semi-structured interviews. The study investigated exposure, sensitivity, perception, and adaptation, leading to the identification of key components and influencing factors. Qualitative research revealed that farms operating in geographically close proximity, in the same regulatory and support environment, can have different adaptive capacities. In the current state of the adaptation process, the extent to which farmers can rely on supportive professional networks and seek out and adopt new practices is crucial. Field experience suggests that without a strong and supportive producer organization (extension network), farmers may prefer to resort to extensification (afforestation) to mitigate production risks. From a development policy perspective, it is worthwhile to present good practices and provide information on possible adaptation techniques through existing local sectoral organizations.

Foliar fertilizing is very important to supply apple plants with calcium and micronutrients. The most cost-effective approach to this is the application of the fertilizers in tank mixtures with plant protection chemicals. Plasma-activated water (PAW) has great potential for the use in the agriculture. We used two type of PAWs, PAW1 (made using underwater electrical discharge in an aqueous KNO3 solution and includes reactive nitrogen species and platinum nanoparticles) and PAW2 (made using a plasma torch with nitrogen gas makeup and contains reactive nitrogen species but not metals). We studied the impact of two PAW types on the contents of Ca, B, Mn, Fe, and Co in leaves and Ca, Mn, Fe, Zn, and Mo in fruits sprayed with tank mixtures containing the fertilizers. We also tested the efficiency of PAW in the control of apple scab when applied as tank mixtures with plant protection chemicals. The application of the PAWs significantly increased foliar Ca when the PAW was mixed with Ca-containing formulations (spraying PAW1 containing Ca increased leaf Ca by up to 21%, and PAW2 up by to 9% compared to Ca spraying without PAW). The largest fruit Ca increase was in the variant treated with PAW1 with a micronutrient spraying program (up to 143%). The PAW treatments enhanced the baseline mineral contents of the plants even when they were not sprayed with the nutrients. PAW1 mainly increased the nutrient contents of the apple fruits. PAWs have proven to be efficient for the control of apple scab, thereby reducing the demand for fungicides. The scab damage to the leaves and fruits was similar in plants treated with PAWs without fungicides (1.7–1.9% on the leaves and 1.6–1.8% on the fruits) compared to the conventional chemical scab control (0.9% leaves and 0.6% fruits) and was significantly lower than in the untreated control (9.3% on leaves and 11.9 on fruits).
叶面施肥对于为苹果植株提供钙和微量元素非常重要。最经济有效的方法是将肥料与植物保护化学品混合施用。等离子活化水（PAW）在农业中的应用潜力巨大。我们使用了两种等离子活化水，一种是等离子活化水 1（在 KNO3 水溶液中使用水下放电法制成，含有活性氮物种和纳米铂颗粒），另一种是等离子活化水 2（使用等离子炬和氮气制成，含有活性氮物种，但不含金属）。我们研究了两种 PAW 对叶片中 Ca、B、Mn、Fe 和 Co 含量的影响，以及对喷洒含有这些肥料的混合液的果实中 Ca、Mn、Fe、Zn 和 Mo 含量的影响。我们还测试了 PAW 与植物保护化学品混合施用时对苹果疮痂病的防治效果。当 PAW 与含 Ca 的制剂混合施用时，PAW 能显著提高叶片 Ca 含量（与喷洒不含 PAW 的 Ca 相比，喷洒含 Ca 的 PAW1 能使叶片 Ca 含量提高 21%，喷洒 PAW2 能使叶片 Ca 含量提高 9%）。果实钙含量增加最多的是用 PAW1 和微量营养元素喷洒程序处理的变体（达 143%）。即使未喷洒营养素，PAW 处理也能提高植物的基准矿物质含量。PAW1 主要提高了苹果果实的养分含量。事实证明，PAW 能有效控制苹果疮痂病，从而减少对杀菌剂的需求。与传统的疮痂病化学防治（叶片和果实分别为 0.9% 和 0.6%）相比，未使用杀菌剂而使用 PAW 处理的植株叶片和果实受到的疮痂病危害（叶片为 1.7-1.9%，果实为 1.6-1.8%）相似，并且明显低于未处理的对照（叶片为 9.3%，果实为 11.9%）。

Citrus fruits have a distinctive flavor and can convey health benefits because of their unique phytochemicals. Phytochemical profiles are influenced by many factors, including variety and environmental growing conditions; however, the effect of the cultivation methods on the phytochemical profile of Satsuma mandarin (Citrus unshiu) has received little attention. In this study, we examined the relationships between the cultivation conditions, sensory quality, and phytochemical profiles of C. unshiu cultivated using four methods: open field, greenhouse, film mulching, and tunnel farming. The soil water content differed significantly between the cultivation methods and showed a strong positive correlation with sourness, bitterness, and astringency and a strong negative correlation with sweetness. The metabolites of C. unshiu were not associated with the soil water content but with the soil mineral content, including nitrogen (N+), phosphorus (P+), and potassium (K+). The soil P+ and K+ content was positively correlated with most secondary metabolites. The relative abundance of sugars did not differ significantly between the cultivation methods; however, the sweetness was higher under film mulching than under the other cultivation methods because of the suppression of sweetness by bitter compounds. We did not investigate the effect of other growing conditions, such as sunlight; however, the results improve our understanding of the effect of cultivation methods on the quality of C. unshiu and may inform crucial decisions concerning citrus cultivation.

We did not investigate the effect of other growing conditions, such as sunlight; however, the results improve our understanding of the effect of cultivation methods on the quality of C. unshiu and may inform crucial decisions concerning citrus cultivation.","PeriodicalId":13034,"journal":{"name":"Horticulturae","volume":"8 3","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139381122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Eastern Europe, the traditional marketing of cyclamen is in the period from the middle of February to the middle of March. The poor light of winter months and the higher number of plants (because of the reduction in heating costs) often result in elongated plants. To avoid this, it is recommended to use plant growth retardants. At the same time, another problem is that flowers do not rise from the level of rosette due to the unfavorable cultivation conditions. This can be solved with growth stimulants. In the experiment, we tested the effect of growth regulators on the growth of a frequently used variety of cyclamen. We used daminozide and paclobutrazol plant growth retardants for height control and gibberellic acid (GA) and benzyladenine (BAP) as growth promoters for increasing the number of flowers and the length of stems. The results show that daminozide and paclobutrazol are both effective for height control in cyclamen production.

Purple tea, renowned for its anthocyanin content and distinctive purple hue, has gained prominence. The anthocyanin content in purple tea can exceed three times that of traditional green-leaf tea. Purple tea harbors various anthocyanins, implicating intricate pathways of biosynthesis and transcriptional regulation. Concurrently, owing to its distinctive chemical composition, the processing of purple tea may be constrained, potentially influencing the sensory attributes and flavor profile of the tea. The richness of anthocyanins in purple tea has yielded potential health benefits, including antioxidative and anti-cancer properties, rendering purple tea a sought-after commodity in the tea market. However, current research on purple tea remains incomplete, including indistinct networks of anthocyanin biosynthesis and regulatory mechanisms, incomplete chemical characterization, and a need for comprehensive investigations into its biological activities. The limited research foundation has greatly reduced the popularity and consumption of purple tea. This paper aims to provide an overview of recent advancements in the biosynthesis and regulation of anthocyanins, as well as the chemical compositions, processing, and health benefits of purple tea. This review will provide the groundwork for future efforts in the selection and innovation of purple tea germplasm, purple tea processing, and the expansion of the market for purple tea consumption.
