不同栽培方式对大麦叶片性状的影响

以云南省新育成的大麦新品种为试验材料,研究了云南大麦生产中的主要栽培方式,即田、地2种方式对大麦叶片性状的影响。结果表明,栽培方式对大麦叶片数量的影响极显著,地麦栽培方式下叶片数明显减少;对旗叶的叶长、叶宽影响不显著,但对叶面积影响极显著;对倒二叶叶长、叶宽、叶面积影响极显著,地麦栽培方式下倒二叶3个性状都极显著的低于田麦栽培方式。叶片叶绿素含量在地麦栽培方式下,在分蘖期、抽穗期、灌浆期3个时期都极显著的高于田麦栽培方式。而不同的品种对栽培方式的反应也存在极显著的差异。因而从叶片性状来看,培育适于旱地栽培的大麦新品种是有可能的。

Effect of Different Cultivation Model on Barley Leaf Characteristics

The barley in Yunnan province mostly was planted in the rain-fed area,accounting for 75 %,while,other 25 % in the irrigated area.In this paper,the barley varieties newly bred in Yunnan were used to investigate the effect of rain-fed and irrigated cultivation model on the leaf characteristics.The results showed that the leaf numbers of barley was significantly reduced on the rain-fed model;the flag leaf length and width was not affected,while the flag leaf area were affected significantly;the effect on the s...
