| 摘 要： | 以中籼稻汕优63(库限制型)和中粳稻广陵香粳(源限制型)为材料,研究高产水稻生育前期的叶面积指数和茎蘖组成特点及其关系.结果表明:(1)高产水稻叶面积指数组成特点为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.(2)高产水稻茎蘖组成特点为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.(3)叶面积指数与茎蘖组成关系为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 composition of stems and tillers and LAI was studied in high-yielding population (Shanyou 63 and Guangling Xiangjing).The results indicated that:(1)The ratio of LAI of tillers of 4 leaf-age and over 4 leaf-age at N-n and elongating stage was high in high-yielding population.(2)The ratio of number of total tiller of 3 leaf-age and 3 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 over 4 leaf-age correlated significantly with the total LAI at elongating stage. |
