采用培养皿种子发芽法,对10个不同白皮小麦品种进行种子活力各项指标及淀粉酶活性测定,结果表明,不同品种间种子活力及淀粉酶活性均存在差异。高活力种子α-淀粉酶活性大。相关分析还显示,α-淀粉酶活性与种子发芽率、发芽指数成高度正相关,致使种子发芽快;小麦收获期遇阴雨潮湿环境易穗上发芽。
The seed germination method of Petri dish was used to measure the seed vigor and amylase activity of 10 different white wheat cultivars. The results showed that there were differences in seed vigor and amylase activity among different varieties. High-activity seed α-amylase activity. Correlation analysis also showed that α-amylase activity and seed germination rate, germination index into a highly positive correlation, resulting in rapid germination of the seed; wheat harvest rainy wet environment prone to spike germination.
