摘要
针对不同水分处理对耗水和产量的特性的影响,在田间对冬小麦不同生育时期进行水分处理。试验结果表明:水分处理对不同基因型小麦的产量构成因素以及产量构成因素间的关系有一定的影响,粒数与千粒重呈极显著的负相关,要提高产量,下一步的育种在稳定粒数的基础上,应该主攻千粒重。
A field experiment was carried out to investigate the effects of water disposal in different growth stage on water consumption and yield in winter wheat. Experimental results showed the effects of water disposal to water consumption and yield structure. The kernel number is negatively correlated with kernel weight on 0.01 significant levels. Improving the yield, the next step in breeding is on the base of stabilization of kernel number and then improving the kernel weight.
