剪穗

剪叶、断根减源还使茎叶鞘贮存物质残留率和穗位叶中叶绿素含量降低，剪穗减库使茎叶鞘贮存物质残留率和穗位叶中叶绿素含量增加。

Reducing source through cutting leaf and cutting root can decrease the residual ratio in stem-sheath and the chlorophyll content of leaf , on the contrary reducing sink through cutting spike can increase the residual ratio in stem-sheath and the chlorophyll content of leaf .

剪叶后多穗型品种豫麦49剩余叶片的光合速率增加较多，粒重降低更为明显；

After leaf-cutting , the photosynthetic rate of remnant leaves of multi-spike cultivar " YM49 " increase a lot and its grain weight fall down even more obviously .

除剪去旗叶穗粒重与对照基本相当外，其余去叶处理穗粒重均低于对照，以去1／2旗叶穗粒重下降幅度最大。

The weight per spike with the treatment of removing leaves was lower than that of CK except the treatment of removing flag leaves , the weight per spike with which was similar to that of CK .
