| 摘 要： | 微粉数量在不同不育系之间、不同播期之间、不同开花时期之间存在显著或极显著差异。随着播期推迟,不育系的微粉下降速率不同,以华油1087的微粉下降速度最快。秦油2号和郑杂4号的微粉量较多,与开花前0℃以上的积温之间存在极显著的正相关。

| Abstract: | There are great or remarkable differences in the number of trace pollen among sterile lines,different sowing times and different florenscences.The decline speed of trace pollen of sterile line was various with the different sowing times and the most quick decline speed was Huayou 1087.Qinyou 2 and Zhengza 4 contained more trace pollen,which were related with the accumulated temperature above 0?℃ before blooming. |
