摘  要:
对油研10号不同播期从出苗到第1株现蕾、出苗到全现蕾、第1株现蕾到全现蕾所经历的天数与日均温进行相关分析,结果表明:从4月7日到5月27日播种均能现蕾,日均温越低,现蕾速度越快,现蕾所经历的时间越短,春化现蕾所历天数与日均温呈显著正相关;对不同播期从第1株现蕾到第1株开花、现蕾期到初花期、第1株开花到全部开花所经历的天数与日均温进行相关分析,结果表明:从4月7日到5月27日播种均能正常开花,日均温越高,开花速度越快,开花所经历的时间越短,春化现蕾所历天数与日均温呈显著负相关。试验结果表明:夏播油研10号从4月7日到5月27日播种均能正常现蕾开花,通过春化。

摘  要:
The results show that the plants of Youyan 10 sowing from 7, April to 27, May all can be able to emerge buds. The more the daily mean temperature decreases, the more quickly the buds emerge, and there is a significant positive correlation between the needed days of bud emergence and daily mean temperature by analyzing the needed days and daily mean temperature of seedling stage to bud emergence, seedling stage to full bud emergence and bud emergence to full bud emergence. The results show that the plants sowing from 7, April to 27, May can flower normally, and the higher the daily mean temperature is, the more quickly the plants flower, and there is a significant negative correlation between the needed days of bud emergence and daily mean temperature by analyzing the needed days of bud emergence to first flowering, bud emergence stage to early flowering and first flowering to full flowering and daily mean temperature.
