研究了春小麦和冬小麦切除叶的持水力.当叶片水分含量减少11-30%时,品种间的差异是容易区别的.冬季与夏季相比,叶片水分含量降低,切除叶的持水力增加.耐早植株表现出较高的持水力.评估了三个冬小麦杂交组合后代切除叶的持水力,后代分布频率呈典型的数量模式.小麦切除叶的持水力似乎是由多基因控制的数量性状.
The water holding capacity of the excised leaves of spring wheat and winter wheat was studied, and the differences among the cultivars were easily distinguished when the water content of leaves was reduced by 11-30% .The water content of leaves was decreased and the water holding capacity of cut leaves increased in winter compared with summer. The early plants showed high water holding capacity, and the water cut of the leaves of three winter wheat hybrids was evaluated.The frequency of progeny distribution was a typical quantitative pattern.The water holding capacity of wheat cut leaves seems to be a quantitative trait controlled by polygenes.
