| 摘 要： | 通过剪穗、剪叶处理,人为改变源库比,研究源库比改变对冷型小麦陕229和暖型小麦NR9405籽粒干物质、可溶性糖、淀粉和总蛋白含量的影响。结果表明,剪去旗叶处理明显降低籽粒干物质积累量,加快花后10~20 d籽粒可溶性糖含量的下降速度,降低花后20~35 d籽粒可溶性糖含量,轻微降低籽粒淀粉含量,但对籽粒蛋白质含量无明显影响。剪去50%小穗处理,明显地增加籽粒干物质积累量,减慢花后10~20 d籽粒可溶性糖含量的下降速度,增加花后20~35 d籽粒的可溶性糖含量,提高籽粒的淀粉含量和蛋白质含量。剪穗、剪叶处理对冷、暖型小麦籽粒物质积累的影响程度不同。

| Abstract: | By means of leaf-cutting and spikelet-removing to change the source-sink ratio,the research studied the effect of changing the source-sink ratio on grain dry weight,soluble sugar content,starch content and total protein content of cold-type wheat Shaan 229 and warm-type wheat NR9405.The results showed that in the treatment of flag leaf-cutting,the grain dry weight accumulation reduced significantly,the decline rate of grain soluble sugar content sped up during 10-20 days after flowering and the soluble suga... |
