摘要

Brassica rapa subsp.Chinensis,俗称大白菜,是一种营养丰富的蔬菜,含有大量抗氧化剂。因此,本研究旨在评估自来水催芽和使用三明治堆肥沥滤液进行生物营养催芽对 280 个来自绿鹰公司的矮小变种大白菜种子的发芽、SPAD 读数和干物质积累的影响。实验过程包括用自来水浇灌、使用 0.2% 的三明治堆肥沥滤液进行生物营养浇灌,以及在土壤中栽培而不浇灌的对照组。采用三次重复的完全随机化设计(CRD)评估了种子发芽性能、SPAD、根和芽干物质以及根芽比。虽然发芽率(88.35±1.13%)没有明显差异,但整个催芽种子的发芽高峰期为 2 天,而未催芽种子的发芽高峰期为 3 天。生物营养素催芽种子的中位数和平均发芽时间更快,这是因为营养素吸收能力增强。它们还显示出较高的 SPAD 读数,表明缺乏有毒化合物。所有处理过的大白菜的干物质产量相似,因为施用的处理方法不会干扰植物的生长和发育。因此,使用三明治堆肥沥滤液进行生物营养催芽对种子发芽性能有积极影响,值得推荐作为种子催芽解决方案。

Effect of Priming on Brassica rapa subsp. chinensis (Bok Choy) Seeds Germination
Brassica rapa subsp. Chinensis, commonly known as Bok Choy, is a nutrient-rich vegetable with substantial antioxidant content. Therefore, this study aimed to evaluate the effect of hydropriming and bio-nutri-priming using Sandwich compost leachate on seed germination, SPAD reading, and dry matter accumulation in 280 dwarf variants of Bok Choy seeds sourced from Green Eagle. The experimental process involved hydropriming with tap water, bio-nutri-priming using 0.2% Sandwich compost leachate, and a control group cultivated in soil without priming. A complete randomization design (CRD) with three replications assessed seed germination performance, SPAD, root and shoot dry matter, and root-to-shoot ratio. While there was no significant difference in the germination percentage (88.35±1.13%), the entire priming seeds exhibited a 2-day peak germination period, compared to 3 days for the non-priming counterparts. Bio-nutri-priming seeds showed faster median and mean germination times due to enhanced nutrient uptake. They further displayed high SPAD readings, suggesting a lack of toxic compounds. The dry matter production of all treated Bok Choy was similar because administered treatments did not interfere with plant growth and development. Therefore, applying bio-nutri-priming using Sandwich compost leachate positively affected seed germination performance, warranting its recommendation as a seeds priming solution.
