摘　　要：对５个甘蔗基因型的群体叶面积指数、冠层相对光照度和蔗茎产量进行了调查研究。结果表明，在伸长期间，基因型间的群体叶面积指数和冠层相对光照度都存在显著差异；蔗茎产量存在极显著差异；叶面积指数与产量、叶面积指数与光照度之间在伸长末期存在显著相关；蔗茎产量主要受群体叶面积的影响，受光照度的影响较小。sugarcane genetypes were used for the experiment which conducted on the leaf area index (LAI) of crop and studies on the relative illumination intensity(RI) and cane yield(Y).The results indicatted that the LAI and RI during the elongation stage and the Y were significant difference among different genetypes;The LAI and RI, LAI and Y during later-elongation stage were significant correlation; on the other hand, the Y was mostly influenced by LAI,while was less influenced by RI.
