摘要
本文采用玉米种子标准发芽试验,比较研究了不同玉米品种及不同大小的玉米种子活力差异。结果表明:比较不同品种的玉米种子活力高低决定于计算种子活力指数的方式,即依靠某一种种子活力指数并不能完全判断不同玉米品种的种子活力高低;同一玉米品种,体积较大或千粒重较高的种子,其活力较高,不同玉米品种间体积大小和千粒重的高低与其种子活力大小之间并无明显的关系。
This study mainly used the seed standard germination test to study the seed vigor of different maize variety and different sizes seeds of maize. The results showed that: the different variety maize seed vigor was determined by the computation way of the seed vigor. Namely, we should not completely depend upon one computation way of seed vigor to judge the maize seed vigor of different maize variety;To the same maize variety, the volume bigger and the weight of a thousand seeds higher, the seed vigor higher,To the different maize variety, there was not obvious relations between maize seed vigor and volume size or weight of a thousand seeds weight.
