摘要： 一株麦苗的主茎和各分蘖的心叶(-1叶)和它里边的一片叶(-2叶)的长度比率,称为-1/-2叶差距。以叶差距为指标反映分蘖、蘖群和植株的生长势,即叶差距小,表示当时和进一步的生长趋势是增强;叶差距大,则表示减弱。一个蘖群中各个分蘖的生长势,在分蘖期,一般表现为子蘖优势,但也有的蘖群和植株表现为亲蘖优势,这一差异可以考虑用于
Abstract: The length ratio between the newly emerging young leaf(-1)and theyounger one (-2) is used as an index (LLR-1/-2) for the reflection ofthe growth potential of tillers,tiller groups and whole plants.The lowervalue of LLR indicates the stronger growth potential.During the tillering period,in general,th
