摘要
为甘蓝型无花瓣优质油菜的选育及杂种优势利用提供参考,对甘蓝型无花瓣与有花瓣油菜在盛花期的田间生态环境进行了比较研究。结果显示:有花瓣油菜群体内的温度随层高的降低而下降明显,无花瓣油菜则下降较缓慢。相对湿度有花瓣油菜随群体层高的下降而升高显著,无花瓣油菜群体随层高的下降,相对湿度的上升则比较缓慢。有花瓣油菜随群体层高的下降,相对光强下降显著,无花瓣油菜群体随层高的下降,相对光强的下降则比较缓慢。表明,无花瓣油菜群体在揭开黄色花瓣层后其群体内的小生境得到了很好的改善。
The field eco-environment of apetalous and petal rape varieties in Brassica nupus were compared to provide a reference for breeding and heterosis of quality apetalous rape varieties. The results showed that the temperature and relative light intensity in the petal rape population reduced significantly with drop of the layer height, that in the apetalous rape population reduced slowly, the relative humidity in the petal rape population rose significantly with drop of the layer height and that in the apetalous rape population rose slowly, which indicates the micro-habitat in the apetalous rape population was improved effectively.
