摘要

"我们在此介绍对从印度不同来源收集的 19 种马陆香(Madhuca indica)种质的种子形态特征和萌发能力进行深入分析的结果"。该研究包括对种子形态特征、萌发参数和生长特性的探索。所调查的性状表现出显著的变异性。值得注意的是,100 粒种子的重量从 346 克到 800 克不等,种子长度从 4 厘米到 2.5 厘米不等,种子直径从 1.92 厘米到 1.41 厘米不等。发芽率在 73.6% 到 46% 之间,成活率在 88.6% 到 71% 之间。关于生长参数,研究记录了幼苗高度和幼苗基部直径。幼苗高度在 12.25 厘米到 12 厘米之间,幼苗基部直径在 5.12 厘米到 2.3 厘米之间。所有评估特征都表现出明显的遗传性,其中成活率的遗传性最高,为 89.54%,种子直径的遗传性最低,为 67.74%。此外,还观察到很大的表型变异系数,表明所研究的种质具有很大的多样性。这种变异性为细致筛选和选择最佳种源提供了宝贵的机会。本研究的发现有助于全面了解马华种质及其潜在应用。

Variability in Seed Morphology, Germination, and Seedling Growth of Madhuca indica: Implications for Seed Source Selection

“We present here the results of an in-depth analysis of the morphometric traits and germination capacity of the seeds of 19 Mahua (Madhuca indica) germplasm collected from diverse sources in India.” The study encompasses an exploration of seed morphometric traits, germination parameters, and growth characteristics. The investigated traits exhibited notable variability. Noteworthy variations were observed in the weight of 100 seeds, ranging from 346 to 800 g, seed length spanning 4–2.5 cm, and seed diameter varying between 1.92 and 1.41 cm. Germination percentages ranged from 73.6 to 46%, while survival percentages showed a range of 88.6–71%. Regarding growth parameters, the study documented seedling height and seedling basal diameter. Seedling height ranged from 12.25 to 12 cm, while seedling basal diameter varied from 5.12 to 2.3 cm. All evaluated characteristics exhibited significant heritability, with survival percentage demonstrating the highest heritability at 89.54%, and seed diameters displaying the lowest at 67.74%. Furthermore, substantial phenotypic coefficient of variability was observed, indicating substantial diversity within the studied germplasms. This variability underscores a valuable opportunities for meticulous screening and selection of optimal seed sources. The findings of this study contribute to comprehensive understanding of Mahua germplasms and their potential applications.
