甲醇老化可使花生种子活力下降,30％甲醇处理量甲醇老化的临界浓度。甲醇老化降低萌发花生种子乙烯的释放量,改变乙烯的释放模式。甲醇老化使细胞透性急剧增加,渗出率比人工老化种子高,而呼吸强度则比人工老化种子低。PEG渗调对低浓度甲醇(10％)老化种子有提高活力的作用,对20％或以上的浓度则有加速种子老化的作用。表明甲醇老化与人工老化对花生种子活力的影响有明显的不同。
Methanol aging can reduce the vitality of peanut seeds, 30% of the methanol treatment capacity of the critical concentration of methanol aging. Methanol aging reduces the release of ethylene from germinated peanut seeds and alters the release pattern of ethylene. Methanol aging cell permeability increased dramatically, exudation rate higher than the artificial aging seeds, while the respiratory intensity is lower than artificial aging seeds. PEG osmosis has the effect of promoting vigor on the low concentration of methanol (10%) aged seeds, and accelerates the aging of the seeds at the concentration of 20% or more. Methanol aging and artificial aging showed significant differences in the vitality of peanut seeds.
