本文以甜椒品种同丰17、古巴甜椒、四道筋为试材,对人工加速老化和PEG引发方法及效果进行了试验研究。结果表明,人工老化能有效地降低种子活力和芽期过氧化物酶活性,是模拟自然老化和测定耐贮性的理想方法之一;PEG引发能逆转老化作用,提高种子活力和茅期过氧化物酶活性。从供试材料看,甜椒种子在20℃下,25～30％PEG引发1～2天,均能有效地提高种子活力,其中以25％或30％的PEG引发1天效果最好。 In this paper, the pepper varieties Tongfeng 17, Cuban bell pepper, four tendons as test materials, accelerated aging and PEG-induced artificial methods and effects were studied. The results showed that artificial aging could effectively reduce seed vigor and peroxidase activity at seedling stage, which was one of the ideal methods for simulating natural aging and determining storability. PEG-induced reversal of aging and seed vigor and maize peroxidation Enzyme activity. From the tested materials, the seeds of capsicum can effectively increase the seed vigor at 25 ~ 30% PEG at 20 ℃ for 1 ~ 2 days. Among them, 25% or 30% PEG induced the best effect on the 1st day.
