| 摘 要： | 试验以源库类型不同的中籼稻汕优63（库限制型）和中粳稻香粳3017（源限制型）为材料,研究高产水稻茎蘖和叶面积指数组成及其关系结果表明:（1）高产水稻茎蘖组成特点:有效分蘖临界叶龄期和拔节期3叶以上大分蘖多,小分蘖少。（2）高产水稻叶面积指数组成特点:有效分蘖临界叶龄期和拔节期3叶以下小分蘖的叶面积指数占总叶面积指数的比例小,与总叶面积指数相关不密切:4叶以上大分蘖的叶面积指数占总叶面积指数比例大,是群体的主要组成部分。（3）叶面积指数与茎蘖组成关系:有效分蘖临界叶龄期3叶以下分蘖数和4叶以上分蘖数与总叶面积指数关系不密切,而拔节期4叶以上分蘖数与总叶面积指数相关显著。

| Abstract: | The relationship between constitution of stems and tillers and LAI was studied in high-yielding population with Shan you 63 and xiang jing 97-3017,the results indicated:(1)The ratio of number of total tiller of 3 leaf-age and older than 3 leaf-age at N-n and elongating stage was high in high-yielding population.(2)The ratio of LAI of tillers of 4 leaf-age and older than 4 leaf-age at N-n and elongating stage was high in high-yielding population.(3)The number of total tillers of 4 leaf-age and older than 4 leaf-age correlated well with the total LAI at elongating stage. |
