低氮胁迫对玉米染色体片段导入系产量和苗期性状的影响
Effects of Low Nitrogen Stress on the Yield and Seedling Traits of Maize Chromosome Fragment Introgression Line in Maize
摘要
Abstract
[Objective] The aim was to study the growth reaction of maize chromosome fragment introgression line under N stress. [ Method ] The changes of yield factor and seedling traits were studied by using maize chromosome fragment introgression line under the normal nitrogen fertilization (N + ) and low nitrogen stress (N - ) conditions. [Result] The Ye478 with five introgression line yield and seedling characters had obvious difference. The yield and seedling biomass were more higher over the 3 treatment stages under N + than N- condition, among them L58 and L28 with little increasing rates were a high nitrogen using efficiency introgression line under nitrogen stress, while L8 with more increasing rates was a low nitrogen using efficiency introgression line under nitrogen stress. [ Conclusion ] The research provides theoretical ba sis for breeding maize varieties with a resistance to low nitrogen.关键词
