| 摘 要： | 对在室温下贮藏不同时间的17个牧草品种,用常规发芽方法进行了萌发及休眠特性的测定。结果表明:禾本科牧草种子在2个月内基本解除休眠,但不耐贮藏,贮藏5年具有发芽能力的种子只有羽茅;豆科牧草种子休眠期比禾本科长,且耐贮藏,贮藏10年的种子多数仍具有一定发芽能力;其它科种子发芽率随贮藏时间的不同没有相应变化规律。

| Abstract: | The germination characteristics of 17 forage species seeds stored in ordinary storehouse for different time were studied through general methods.The results showed that grass species could break dormancy in 2 month and did not stand storage.Only Achmathenm beauv had germination ability after stored for 5 years.Leguminous species seeds had a long dormancy time and could stand storage.Most of Leguminous species seeds had germination ability after 10_year storage.The germination percentage of other seeds had not relative change regularity. |
