| 摘 要： | 以叶色倒置小麦为材料,通过对叶色倒置小麦中倒置茎和正置茎上一些重要的形态、生理和产量等指标的测定及比较.进一步研究小麦叶片非顺序衰老的生物学特性,探讨其理论意义和实践价值.结果表明,倒置茎上旗叶先于倒二叶衰老,与此相呼应,在结实后期旗叶的绿叶面积比<倒二叶绿叶面积比,旗叶叶绿素含量<倒二叶叶绿素含量,伴随这种生理变化下...

| Abstract: | Leaf-color inverted wheat are used as material to survey and compare the important indexes of morph,physiology and production of the wheat so as to study the laws of inverted senescing sequence of wheat leaves and to reveal its significances in theory and practice.The results show that the flag leaf of the inverted sequence stem ages before the second leaf and consequently the flag leaf area and chlorophyll content are smaller than those of the second leaf in the latter period of its maturity.The physiologi... |
