摘要
对大麦叶色转换突变系的研究结果表明：大麦叶色转换突变系的叶色转换特性是受遗传与环境因素共同控制的，植株转色的表现要有适宜外界环境条件的诱导，否则与其它间类型的大麦无异；植株转色的根本原因是叶根素合成代谢变化的结果，突变系转色期间叶绿素的合成过程受阻，且受阻部位在ＡＬＡ形成之后；突变系叶色转换特性的表现是由隐性、单核基因控制的．
The experiment was conducted with four types of leaf colour conversion mutant lines of barley and their CK on the characteristics of leaf colour conversion and its heredity.It was shown that the leaf colour conversion was controlled by its heredity and environment factors (mainly temperature) and that its expression would be reduced by certain experimental factors (low temperature). There was less chlorophyll content in the leaves of the mutant lines compared with CK during the colour conversion; period,and accumulationj of ALA was found in the same period as well. This explains that the decrease of chlorophyll content was possibly caused by its bio-inhibition, which caused the expression of the leaf colour conversion; The heredity of the characteristics of leaf colour conversion was controlled by the single recessive gene.
