Comparison of the water potentials of leaf, sheath and culm has done.

对春小麦叶鞘、叶片和茎水势的变化情况进行了比较。

The result shows that the unit weight of culm changes along with the age of culm.

结果表明，竹杆容重随年龄的变化反映了毛竹个体独特的生长分化特点。

But as concentration of brown rice has most positively correlation to that of culm.

穗茎节砷含量与糙米砷含量之间呈极显著正相关。

In vitro, leaf number per culm became more; and the lower node was, the more increase was.

离体条件下单苗叶片数有所增加，且节位越低增加越多。

The higher content of that in culm and sheath was a character of active carbohydrate metabolism.

茎鞘中高含量的可溶性糖是茎鞘碳水化合物代谢活跃的特征；
