The in vitro propagation techniques are currently a commercial alternative for the production of plants with good quality in several plant species, including the olive tree (Olea europaea L.). Somatic embryogenesis is the process practically used for the application of several biotechnological tools of improvement and in vitro plant regeneration via the germination of somatic embryos. Our work aims to evaluate the effect of the chemical and hormonal composition of the culture medium on the germination of olive somatic embryos (cv. Chemlal) as well as the micropropagation of the obtained plantlets before their acclimatization to natural conditions. The results indicated that the production of olive plants by somatic embryogenesis depends strongly on the genotype of the somatic embryos (cell line) and more on the culture conditions, particularly the presence of growth regulators. Indeed, a solid OM medium supplemented with hormones (BA and IBA) permitted an advanced root emergence and germination allowing the production of well-developed plants with several leaves. In addition, an OM medium supplemented with Zeatin and IBA allowed better reactivity of micro-cuttings producing well-developed shoots with several emitted roots which facilitates their further acclimatization to natural conditions.
目前,体外繁殖技术已成为包括橄榄树(Olea europaea L.)在内的几种植物中生产优质植物的商业替代技术。体细胞胚胎发生是通过体细胞胚胎的萌发,实际应用于几种生物技术手段的改良和离体植株再生的过程。我们的工作旨在评价培养基的化学和激素组成对橄榄体细胞胚萌发的影响。以及在获得的植株适应自然条件之前进行微繁殖。结果表明,橄榄植株的体细胞胚发生主要取决于体细胞胚(细胞系)的基因型,而主要取决于培养条件,尤其是生长调节剂的存在。事实上,添加了激素(BA和IBA)的固体OM培养基可以促进根的萌发和发芽,从而产生发育良好的有几片叶子的植株。此外,在添加玉米素和IBA的OM培养基中,微插条的反应性更好,产生发育良好的芽和几个根,有利于它们进一步适应自然条件。

postharvest applications of Calcium and gibberellic acid have proved to maintain optimal fruit quality and control decay during cold storage. This study evaluated the effect of calcium and gibberellic acid dipping application on pineapple quality and internal browning. The experiment implemented two factors. The first factor concerning two dipping times (five and ten minutes) and the second factor related to four treatments, A (gibberellic acid), B (calcium), C (calcium + gibberellic), and control (D) - (no calcium or gibberellic acid applied). Total soluble solids (TSS), total acidity (TA), TSS/TA ratio, sugar, citric and ascorbic acid content, together with browning severity and incidence, were determined. Treatment B, essentially using a dipping time of five minutes, delivered the best performance having the lowest severity and incidence of browning (4.44 and 22.22 %, respectively), the highest citric acid (0.61 %), ascorbic acid content (405.18 mg kg-1) and TSS/TA ratio (25.53). Meanwhile, the other treatments were considered less satisfactory, due to their highest browning severity and incidence, without remarkable impact on the citric acid and ascorbic acid content, especially with a dipping time of ten minutes. In conclusion, dipping applications of calcium and gibberellic in postharvest enhanced pineapple quality and reduced the internal browning.
采后施用钙和赤霉素酸已被证明可以保持最佳的果实品质,并在冷藏过程中控制腐烂。本研究评价了钙和赤霉素酸浸施对菠萝品质和内部褐变的影响。该实验实现了两个因素。第一个因素涉及两次浸渍时间(5分钟和10分钟),第二个因素涉及四种处理,A(赤霉素),B(钙),C(钙+赤霉素)和对照(D) -(不施用钙或赤霉素)。测定了总可溶性固形物(TSS)、总酸度(TA)、TSS/TA比、糖、柠檬酸和抗坏血酸含量以及褐变严重程度和发生率。浸渍时间为5分钟的处理B表现最佳,褐变的严重程度和发生率最低(分别为4.44%和22.22%),柠檬酸和抗坏血酸含量最高(0.61%),TSS/TA含量最高(405.18 mg kg-1), TSS/TA比值最高(25.53)。同时,其他处理的褐变程度和发生率最高,对柠檬酸和抗坏血酸含量没有显著影响,特别是浸渍时间为10分钟时。综上所述,采后浸施钙和赤霉素可提高菠萝品质,减少菠萝内部褐变。

The Endemic Juniper of Maymars (Juniperus sabina) is one of the most valuable plants in forested areas. The objectives of this experiment were: I) to determine the best conditions for stem cutting propagation of this species, and II) to examine changes in some of the secondary metabolites during the four months (the first of each season): January, April, July, and October, after rooting of cuttings. The research was done with the treatment of five levels of Indole Butyric Acid, including: 0, 1000, 2000, 4000, and 8000 ppm in four rooting substrates, including perlite, perlite-cocopeat (1:1), pumice, and a mixed rooting substrate (sand, perlite, cocopeat, vermicompost, and potash; 1:1:1:1:1) in the four seasons of the year, with stem cuttings having an average length of 15 cm. The best treatment with more than 50% rooting was seen in April at levels of 4000 and 1000 ppm, and the best substrate was perlite cocopeat. Using lower levels of IBA led to a reduction in total phenol content in the cuttings during the rooting period. The flavonoid content of the cuttings varied across different seasons. Based on these results, we recommend this way of propagation for Juniperus sabina production. This propagation method takes less time in comparison with sexual propagation from seed.
Maymars特有的桧(Juniperus sabina)是森林地区最有价值的植物之一。本试验的目的是:1)确定该树种扦插繁殖的最佳条件;2)考察扦插生根后1月、4月、7月和10月四个月(每个季节的第一个月)一些次生代谢物的变化。在珍珠岩、珍珠岩-鸡粪(1:1)、浮石和混合生根基质(砂、珍珠岩、鸡粪、蚯蚓堆肥和钾肥)中,分别以0、1000、2000、4000和8000ppm的吲哚丁酸水平处理4种生根基质;(1:1:1:1:1)一年四季生长,茎枝平均长度为15厘米。在4月份,4000和1000ppm的处理生根率达到50%以上的效果最好,基质为珍珠岩椰泥。使用较低水平的IBA导致生根期插条中总酚含量降低。不同季节插条中黄酮类化合物含量不同。根据这些结果,我们推荐这种繁殖方式用于桧的生产。与种子有性繁殖相比,这种繁殖方法所需的时间更短。

Parthenocarpy, the ability of some plants to undergo fruit growth in absence of fertilization, is an important question of basic science and the subject of much interest due to its possible agricultural benefits. In the context of our cellular biology studies on a halophyte of interest, Cakile maritima, we generated calli, pluripotent cell masses, that unexpectedly allowed the appearance of parthenocarpic fruits without any floral tissues. These observations raise the hope to develop an in vitro model to study parthenocarpic fruit development.
单性生殖是一些植物在没有受精的情况下进行果实生长的能力,是一个重要的基础科学问题,由于其可能的农业效益而备受关注。在我们对一种感兴趣的盐生植物——海芽草(Cakile marima)的细胞生物学研究中,我们产生了愈伤组织,这是一种多能细胞团,出乎意料地允许出现没有任何花组织的单性果实。这些观察结果为建立研究孤雌果实发育的体外模型带来了希望。

Indonesia is one of the major countries which contributes the world’s guava production. Guava var. Getas Merah is commonly found in Indonesia. Guava has a short shelf-life as it rapidly goes under postharvest ripening. This leads to a faster deterioration of physicochemical and sensorial properties of guava. A generally used method to extends shelf-life is by edible coating. In this study, a combination of alginate and Cyclea barbata leaves powder (CBLP) was investigated as a potential edible coating. The analysis of firmness, total soluble solids, total reducing sugar, total titratable acidity and organoleptic tests were conducted to evaluate the quality of guava fruits stored for 20 d at 14°C. A split plot design study was used and four different treatments with different CBLP concentrations were applied. The samples treated with 2% alginate and 0.8% CBLP showed the lowest total dissolved solids, total reducing sugar, and total titratable acidity. Moreover, the samples were reported with the highest score on color, taste, and texture parameters. The firmness test showed that samples treated with 2% alginate and 0.2% CBLP had the lowest firmness loss and highest score for aroma. In summary longer quality retention of guava fruits was found after the addition of CBLP in alginate-based edible coating.
印度尼西亚是世界番石榴产量的主要贡献国之一。番石榴在印度尼西亚很常见。番石榴的保质期很短,因为它在采后迅速成熟。这导致番石榴的物理化学和感官特性更快地恶化。延长保质期的一种常用方法是通过食用涂层。在本研究中,海藻酸盐和倒钩环孢叶粉(CBLP)的组合被研究为一种潜在的可食用涂层。通过硬度、总可溶性固形物、总还原糖、总可滴定酸度的分析和感官测试来评估在14°C下储存20天的番石榴果实的质量。采用分块设计研究,采用四种不同浓度CBLP的不同处理。用2%藻酸盐和0.8%CBLP处理的样品显示出最低的总溶解固体、总还原糖和总可滴定酸度。此外,据报道,这些样品在颜色、味道和质地参数方面得分最高。硬度测试表明,用2%藻酸盐和0.2%CBLP处理的样品的硬度损失最低,香气得分最高。总之,在海藻酸盐基可食用涂层中添加CBLP后,番石榴果实的质量保持期更长。

Although the effect of salinity stress on some species of Salvia has been studied, so far no research has been done on S. lavandulifolia species. Therefore, a greenhouse pot experiment was carried out to investigate the impacts of salt stress on vegetative parameters, chlorophyll content, and antioxidants activity in Salvia lavandulifolia Vahl. Treatments included different irrigation water salinity levels (S0=1.3, S1=3.3, S2=5.3, S3=7.3, S4=9.3, S5=11.3, and S6=13.3 dS m-1) which were arranged in a completely randomized design. The results showed that salinity treatments significantly affected the plant growth attributes. The lowest plant height, leaf number, leaf length, and shoot dry weight was recorded in the S6 treated plants with 62%, 41%, 44%, and 82% decrease compared to the control, respectively. Treatment of S. lavandulifolia plants with the highest salinity level (S6) decreased the content of chlorophyll a, chlorophyll b, and total chlorophyll by 57%, 53%, and 54% compared to the control, respectively. Salt stress at all levels increased the total phenolic content, and the highest value was obtained in the S6 treated plants. Free radical scavenging capacity was significantly increased by all the levels of salinity stress, and the highest (85.14%) value was obtained in the S6 treated plants. In general, S. lavandulifolia can be classified as a species-sensitive plant.
虽然盐度胁迫对一些鼠尾草品种的影响已经被研究过,但到目前为止还没有对lavandulifolia品种的研究。为此,通过温室盆栽试验,研究了盐胁迫对鼠尾草营养参数、叶绿素含量和抗氧化活性的影响。不同灌溉水盐度水平(S0=1.3, S1=3.3, S2=5.3, S3=7.3, S4=9.3, S5=11.3, S6=13.3 dS -1)采用完全随机设计。结果表明,盐渍化处理对植株生长性状有显著影响。S6处理植株株高、叶数、叶长和地上部干重最低,分别比对照降低62%、41%、44%和82%。最高盐度(S6)处理的薰衣草叶片叶绿素a、叶绿素b和总叶绿素含量分别比对照降低57%、53%和54%。各级盐胁迫均使总酚含量增加,以S6处理植株最高。各盐度胁迫水平均显著提高了植株的自由基清除能力,其中S6处理植株的清除能力最高,达到85.14%。一般来说,薰衣草属属物种敏感植物。

Tomatoes, being highly perishable, experience extreme post-harvest losses due to improper packaging materials. Experimentation was done to investigate the effect of different packaging materials on shelf life and quality traits of tomato var. Srijana at the horticulture laboratory of the Institute of Agriculture and Animal Science, Lamjung Campus under a completely randomized design. Seven treatments viz. no packaging (control), unperforated low-density polyethylene (LDPE) bag, perforated (4 holes of 2 mm) LDPE bag, unperforated high-density polyethylene (HDPE) bag, perforated HDPE bag, unperforated non-woven fabric bag, and perforated non-woven fabric bag with 3 replications were used. Tomatoes were evaluated for weight loss, color development, total soluble solids, titratable acidity, pH, and shelf life. Among the treatments, the lowest percentage of weight loss (0.66%) was observed on tomatoes packed in an unperforated HDPE bag, however, it had a higher fungus attack. No packaging group showed rapid shriveling of fruits with the highest percentage of weight loss (14.70%). Although packaging in a non-woven fabric bag was better than control, it showed a higher percentage of weight loss than plastic packaging due to its high permeability to gases and water vapor. The TSS and pH values were found to be higher and TA to be lower in no packaging compared to other packagings. The longest shelf life of tomatoes was observed in perforated LDPE (24 days), followed by HDPE (23 days) whereas the lowest was observed in control (16 days). Overall, the perforated plastic packaging was found best among all treatments with no significant variation among perforated HDPE and perforated LDPE for maintaining qualities of tomatoes and longer shelf life.
西红柿极易腐烂,由于包装材料不当,收获后损失极大。采用完全随机设计,研究了不同包装材料对Srijana番茄品种保质期和品质性状的影响。采用无包装(对照)、无穿孔低密度聚乙烯(LDPE)袋、穿孔(4孔2mm) LDPE袋、无穿孔高密度聚乙烯(HDPE)袋、穿孔HDPE袋、无穿孔无纺布袋、穿孔无纺布袋7个处理,共3个重复。评估番茄的失重、显色、总可溶性固形物、可滴定酸度、pH值和保质期。在所有处理中,未穿孔HDPE袋装番茄的减重率最低(0.66%),但真菌侵染率较高。无包装组水果迅速萎缩,失重率最高(14.70%)。尽管无纺布袋的包装效果好于对照,但由于无纺布袋对气体和水蒸气的渗透性高,因此其减重率高于塑料包装。与其他包装相比,未包装的TSS和pH值较高,TA较低。穿孔LDPE贮藏期最长(24 d), HDPE次之(23 d),对照贮藏期最短(16 d)。总体而言,在所有处理中,穿孔塑料包装的效果最好,在保持番茄品质和延长保质期方面,穿孔HDPE和穿孔LDPE之间没有显著差异。

Experimentation was done to investigate the effect of different packaging materials on shelf life and quality traits of tomato var. Srijana at the horticulture laboratory of the Institute of Agriculture and Animal Science, Lamjung Campus under a completely randomized design. Seven treatments viz. no packaging (control), unperforated low-density polyethylene (LDPE) bag, perforated (4 holes of 2 mm) LDPE bag, unperforated high-density polyethylene (HDPE) bag, perforated HDPE bag, unperforated non-woven fabric bag, and perforated non-woven fabric bag with 3 replications were used. Tomatoes were evaluated for weight loss, color development, total soluble solids, titratable acidity, pH, and shelf life. Among the treatments, the lowest percentage of weight loss (0.66%) was observed on tomatoes packed in an unperforated HDPE bag, however, it had a higher fungus attack. No packaging group showed rapid shriveling of fruits with the highest percentage of weight loss (14.70%). Although packaging in a non-woven fabric bag was better than control, it showed a higher percentage of weight loss than plastic packaging due to its high permeability to gases and water vapor. The TSS and pH values were found to be higher and TA to be lower in no packaging compared to other packagings. The longest shelf life of tomatoes was observed in perforated LDPE (24 days), followed by HDPE (23 days) whereas the lowest was observed in control (16 days). Overall, the perforated plastic packaging was found best among all treatments with no significant variation among perforated HDPE and perforated LDPE for maintaining qualities of tomatoes and longer shelf life.","PeriodicalId":7339,"journal":{"name":"Advances in horticultural science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45257447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intercropping and biofertilizers application are the most important agricultural methods for moving towards minimizing the risks of agricultural production and increasing production efficiency. Consequently, this experiment was conducted at one year and in 2019. A factorial set of treatments was arranged within randomized complete block design (RCBD) with three replications to investigate the effect of different planting ratios with safflower and soybean (sole cropping, 30:100 soybean to safflower ratio, 60:100 soybean to safflower ratio and 90:100 soybean to safflower ratio) and nutrient levels (100% urea fertilizer, 100% biofertilizer and the combined application of urea and biofertilizer) on growth and yield of these crops. The results of this study indicated that intercropping patterns had the highest plant height, number of grains per plant, biological and grain yields. In addition, the means of the number of heads per plant and the number of grains per head in safflower and the weight of 1000 grains in soybean were increased as intercrops were grown. Maximum of grain number per plant in safflower, leaf number per plan in soybean and biological and grain yields in both crops were attained in urea + biofertilizer. In all of intercropping patterns the values of LER (land equivalent ratio), RVT (relative value total) and RCC (relative crowding coefficient) was more than one, indicating an advantage from intercropping over sole crops.
间作和施用生物肥料是减少农业生产风险和提高生产效率的最重要的农业方法。因此,该实验在1年和2019年进行。采用随机完全区组设计(RCBD),设计3个重复,研究红花与大豆不同种植比例(单作、30:100大豆与红花、60:100大豆与红花和90:100大豆与红花)和养分水平(100%尿素肥、100%生物肥和尿素与生物肥配施)对这些作物生长和产量的影响。结果表明,间作模式具有最高的株高、单株粒数、生物产量和粮食产量。此外,随着间作的增加,红花的单株穗数、单株粒数均值和大豆的千粒重均有所增加。在尿素+生物肥处理下,红花单株粒数、大豆单株叶数以及两种作物的生物产量和粮食产量均达到最大。在所有间作模式中,土地等效比(LER)、相对总价值(RVT)和相对拥挤系数(RCC)均大于1,表明间作优于单一作物。

Information on gene action controlling quantitative traits is important for effective selection. A five-parent diallel cross, which generated 10 F1 hybrids of okra (Abelmoscus esculentus) were evaluated during the early and late planting seasons of 2019 in Ibadan, Nigeria. Data obtained were subjected to diallel analysis and genotype by yield-trait (GYT) biplot analysis to estimate combining ability effects and identify stable hybrids for measured traits respectively. Genotype mean squares were significant (p≤0.01) for all most measured traits. Furthermore, General Combining Ability (GCA) and Specific Combining Ability (SCA) mean squares were significant (p≤0.05/0.01) for most measured traits, indicating the influence of additive and non-additive gene actions in expression of these traits. Preponderance of non-additive gene effects shows the high influence of the environment on most of the considered traits in this study. Iwo Nla had the most desirable GCA estimates of -0.98 and 1.14, for days to 50% flowering (DTF), number of fruits per plant (NoF) respectively while IK11 had the most desirable GCA values for mature-fruit width (0.21) and 1000-seed weight (5.71). SCA estimates were most desirable for NH47-4 × LD88, NH47-4 × Iwo Nla, with values of -4.21 and 4.32 for DTF and NoF respectively. Hybrids NH47-4 × Iwo Nla and IK11 × Clemson associated with higher NoF x trait might be useful for improvement of number of fruits per plant in this population.
控制数量性状的基因作用信息对于有效选择是重要的。在2019年尼日利亚伊巴丹的早、晚种植季节,对一个产生10个秋葵F1杂交种(Abelmoscus esculentus)的五亲本双列杂交进行了评估。对所获得的数据进行双列杂交分析和产量性状基因型(GYT)双位点分析,以估计配合力效应,并分别为所测性状鉴定稳定的杂交种。基因型均方对于所有大多数测量的性状都是显著的(p≤0.01)。此外,一般配合力(GCA)和特异配合力(SCA)均方在大多数测定性状中均显著(p≤0.05/0.01),表明加性和非加性基因作用对这些性状表达的影响。非加性基因效应的优势表明,环境对本研究中考虑的大多数性状都有很大的影响。Iwo-Nla在50%开花天数(DTF)和单株果实数(NoF)方面的GCA估计值分别为-0.98和1.14,而IK11在成熟果实宽度(0.21)和1000粒种子重量(5.71)方面的GC A估计值最理想。NH47-4×Iwo-Nla和IK11×Clemson与较高的NOFx性状相关的杂交种可能有助于提高该群体的单株果实数。

Pomegranate fruit is very popular due to its high commercial importance and health benefits. This experiment aimed to evaluate the sensory quality, color, and biochemical properties (TSS, TA, TSS/TA, anthocyanin content and total antioxidant capacity) of pomegranate fruit under post-harvest treatments, included ethanol (EtOH), sodium bicarbonate (SBC), and different packaging. Experimental treatments included: 10% (v/v) EtOH, 1% (w/v) SBC, and the type of packaging (passive-MAP and vacuum). Fruit were then stored at 5±1°C and 90% relative humidity for ten weeks. The peel and aril color evaluations indicate that EtOH treatment and vacuum packaging (VP) improved the quality of pomegranate color by increasing a* and decreasing L*. These treatments made the skin color and aril color lighter and redder in pomegranate. In addition, the treatments reduced decay and maintained total soluble solids (TSS), and titratable acidity (TA). Interestingly, EtOH treatment improved fruit nutritional quality as it increased total antioxidant capacity and anthocyanin content by 20% and 50%, respectively, compared to the control. The sensory analysis indicated that treated fruit with EtOH and VP scored higher in taste, color, texture, and appearance, and showed the best acceptability from the panelists’ viewpoint. In conclusion, EtOH and VP significantly improved pomegranate fruit quality during cold storage since preserved sensorial quality and bioactive compounds and reduced decay.
石榴因其高度的商业重要性和健康益处而广受欢迎。本实验旨在评估石榴果实在收获后处理(包括乙醇(EtOH)、碳酸氢钠(SBC)和不同包装)下的感官品质、颜色和生化特性(TSS、TA、TSS/TA、花青素含量和总抗氧化能力)。实验处理包括:10%(v/v)EtOH、1%(w/v)SBC和包装类型(被动MAP和真空)。然后将水果在5±1°C和90%相对湿度下储存10周。果皮和假种皮的颜色评价表明,EtOH处理和真空包装(VP)通过增加a*和减少L*来改善石榴的颜色质量。这些处理使石榴的肤色和假种皮颜色越来越浅、越来越红。此外,这些处理减少了腐烂,并保持了总可溶性固体(TSS)和可滴定酸度(TA)。有趣的是,与对照相比,EtOH处理提高了水果的营养质量,使其总抗氧化能力和花青素含量分别提高了20%和50%。感官分析表明,用EtOH和VP处理的水果在味道、颜色、质地和外观上得分更高,从小组成员的角度来看,表现出最佳的可接受性。总之,EtOH和VP在冷藏期间显著改善了石榴果实的品质,因为它们保留了感官品质和生物活性化合物,并减少了腐烂。
