为评价抗草铵膦转基因杂交油菜对草铵膦的抗性,以转bar基因抗草铵膦杂交油菜“7748”为材料,在2个密度水平和4种除草剂下,以油菜单株鲜重、株高、单株叶面积、净光合速率、SPAD值、全株角果数、每角粒数、千粒重等为指标,研究了草铵膦及其对照药剂对抗草铵膦转基因杂交油菜生长、产量及产量构成、品质的影响.结果表明,草铵膦处理后4d之内油菜叶绿素相对含量、净光合速率极显著低于对照,15d左右内油菜单株鲜重、单株叶面积极显著低于对照,20 d左右内油菜株高极显著低于对照,但药后1个月左右均超过对照.密度间、密度与除草剂交互作用差异显著,密度间以高密度的平均产量最高,除草剂间以草铵膦处理的...

In order to evaluate the resistance of glufosinate - resistance transgenic hybrid rape to glufosinate, effects of herbicide application and plant density on growth and yield and its components of transgenic hybrid rape were studied with bar - transgenic hybrid rapeseed line ＂7748＂ as material under two densities and four herbicides. The results showed that the net photosynthetic rate and SPAD of the transgenic rapeseed were very significantly lower than control within 4 days af- ter treatment with glufosinate, the fresh weight and leaf area w...
