转基因玉米株高、ASI和穗部性状与抗旱性的关系研究
Relationship between Plant Height, ASI and Ear Traits and Drought Resistance of Transgenic Corn
摘要
Abstract
[ Objective ] Drought is one of major factors to restrict China's corn production, and the application of transgenic technology can effectively improve the efficiency of corn drought breeding. [Method] Through the drought stress in period of flowering, and taking identification and evaluation of drought resistance on 61 transgenic corn materials, this paper studied the relationship between transgenic corn ASI, plant height, the yield and drought resistance, the change of these ratio on the kernel weight and ear weight, cob diameter and ear diameter, 100 - kernel volume and 100 - kernel weight affected by drought, and die effect of improving the drought resistance of corn by transgenosis on the basis of its receptor. [ Result] The experiments'results showed that in normal irrigation conditions, the yield was higher, but when affected by the drought later, die plant height was decreased, and normally the small transgenic corn ASI have a strong drought resistance. [Conclusion] The drought resistance of transgenic corn can be improved by 25% -53% on the basis of its receptor. The proportional relation between ear weight and seeds might be a key approach to raise its yield to a high degree.关键词
