本文对大豆(Glycine max)种子渗出液的pH值与种子发芽之间的相关性作了研究,所用品种“Bragg”来自十九个不同产地。将单个种子置于一盛有3.5ml纯水塑料容器内,在25℃下浸泡20小时,测定每粒种子渗出液的pH值,然后将种子置于纸床发芽,在纸床上作上标记以辩别各粒种子。种子渗出液的pH值与种子发芽之间存在密切相关。pH5.80是有生活力和无生活力种子的分界点。 In this paper, the correlation between the pH value of seed exudates of soybeans (Glycine max) and seed germination was studied. The variety “Bragg” was derived from 19 different habitats. A single seed was placed in a plastic container containing 3.5 ml of pure water and soaked at 25 ° C for 20 hours. The pH of the exudate was measured for each seed, and the seeds were germinated in a paper bed and marked on a paper bed To distinguish each grain seeds. There is a close correlation between the pH of the seed exudates and seed germination. pH 5.80 is the demarcation point for viable and non-viable seeds.
