摘要

禾谷类作物(Vigna radiata L. Wilczek)通常被称为绿豆或 Vigna radiata,是一种重要的豆类作物。脉动作物产量低的主要原因是使用劣质种子、作物管理不当以及在贫瘠土壤中种植。可以通过创造低成本、适宜的种子生产技术来提高产量。研究表明,海藻提取物可以改善作物生长发育,增加作物在困难和典型环境下的养分吸收。通过降低真菌和昆虫侵袭的频率,海藻提取物的使用在作物产量、养分吸收、抗冻和抗压能力以及种子发芽方面都取得了令人鼓舞的成果。根据上述观点,我们开展了一项研究,以了解海藻提取物在辐射木葡萄无菌条件下对种子质量性状的影响。该实验室实验旨在评估海藻提取物(即 Kappaphycus alvarezii 和 Gracilaria)对绿禾品种 VBN 2 的发芽、生长和种子质量性状的影响。VBN 2。该实验于 2022 年在安纳马拉伊大学遗传学和植物育种系进行。第一步是将种子在双蒸馏水中浸泡六小时。经过初步预浸泡后,种子在室温下晾干。然后,将预先浸泡过的种子浸入不同浓度的海藻提取物中。Kappaphycus alvarezii 的浓度分别为 1.5%、2.5%、3%、1% 和 2%,Gracilaria 的浓度分别为 2.5%、5% 和 10%。将不同量的海藻提取物浸泡种子六小时。用纸巾将处理过的种子播种,以收集数据并进一步观察幼苗。结果表明,与其他处理相比,用浓度为 2.5% 的海藻提取物浸泡的种子在各种种子质量指标上表现出最高值,即发芽率(81)、根长(16.57)、芽长(19.64)、鲜重(38.58)、干重(34.76)、干物质产量(197.53)、幼苗活力指数(3452)和四唑试验(80)。用石蒜浸泡的种子在不同浓度的石蒜处理中没有显示出任何差异,而在对照中观察到的成活率最低。

Influence of seaweed extract on seed quality traits under in-vitro conditions in green gram (Vigna radiata L.) cv. VBN 2
Green gram (Vigna radiata L. Wilczek), commonly referred to as mung bean or Vigna radiata, is an important pulse crop. The main causes of low pulse productivity were identified as the use of inferior seed, inappropriate crop management, and cultivation in marginal soils. It could be improved by creating low-cost seed production technology that is appropriate. It has been shown that seaweed extracts can improve crop development and increase nutrient uptake in both difficult and typical environmental situations. By reducing the frequency of fungal and insect attack, the use of seaweed extracts has led to encouraging gains in crop output, nutrient uptake, resilience to frost and stress, and seed germination. By keeping the aforesaid point of view, a study was conducted to know the effectiveness of seaweed extract on seed quality traits under invitro condition of Vigna radiata. The laboratory experiment aimed to evaluate the effect of seaweed extracts viz., Kappaphycus alvarezii and Gracilaria on the germination, growth and seed quality traits of green gram variety cv. VBN 2. The experiment was carried out in Department of Genetics and Plant Breeding, Annamalai University during the year 2022. The first step involved steeping the seeds in double-distilled water for six hours. Following their initial pre-soaking, the seeds were left to air dry at room temperature. Then, submerged the pre-soaked seeds in varying quantities of seaweed extract. Concentrations of 1.5%, 2.5%, 3%, 1% and 2% were utilized for Kappaphycus alvarezii and 2.5%, 5% and 10% were used for Gracilaria. For six hours, the various amounts of seaweed extract were soaked into the seeds. Paper towels were used to sow the treated seeds in order to collect data and observe the seedlings further. The results revealed that seeds soaked with Kappaphycus alvarezii at a concentration of 2.5% exhibited highest value for various seed quality parameters viz., germination percentage (81), root length (16.57), shoot length (19.64), fresh weight (38.58), dry weight (34.76), dry matter production (197.53), seedling vigour index (3452) and tetrazolium Test (80), compared to other treatments. Seeds soaked with Gracilaria didn’t show any variation among the different concentration treatments of Gracilaria, while minimum viability percentage was observed in control.
