| 摘 要： | 以授粉后不同时间收获的玉米单交种郑单958为试验材料,研究了不同收获时间对种子发芽率、百粒重以及种子萌发过程中可溶性糖、淀粉含量和贮藏物质运转的影响.结果表明,授粉后40d收获的玉米种子其发芽率最低,未达到国家玉米良种发芽率85％的标准,而授粉后55 d收获的玉米种子其发芽率最高,为97.3％.授粉后60d收获的玉米种...

| Abstract: | Using single-cross Zhengdan958 hybrid maize harvested at different time after pollination as experimental material,studied how different harvest time affected germination rate of maize seeds,100-seed weight and soluble sugar content during seed germination,starch content and reserve transportation.The results showed that maize seeds harvested after 40 d of pollination,with had the lowest germination rate failed to meet the national standard rate,which was 85%;and seeds harvested after 55 d had the highest g... |
