运用细胞离析法对水、旱条件下种植的水、早稻不同叶位叶片的叶肉细胞形态作了观察。结果发现:无论水稻、旱稻其叶片叶肉细胞均表现为具有多个不同方向分枝的分枝状细胞以及少量的环状细胞;随叶位上升,无论水稻、旱稻,不论水种还是旱种都表现出细胞的平均分枝数逐渐上升的趋势。同时还发现:不论水、旱稻凡旱种条件下其各叶位叶片叶肉细胞的平均分枝数除水稻品种合江20的上部几叶外,其它品种均多于水种条件下的相应叶片。可以认为:上述叶肉细胞的变化一方面应与叶片光合功能的增强有关,另外也反映了栽培环境改变后叶片叶肉细胞结构在生态适应方面的变化。
The morphology of mesophyll cells in leaves of different leaf positions of early rice and rice planted under water and drought conditions was observed by cell isolation method. The results showed that the leaf mesophyll cells of rice and upland rice showed branched cells with many branches and a few of annular cells. With the increase of the leaf position, both mesophyll and upland rice The average number of cells showed a gradual upward trend. It was also found that the average number of branches of leaf mesophyll cells of all leaves except for water and paddy rice was higher than that of the upper leaves of Hejiang 20, the other varieties were more than the corresponding leaves under water conditions. It can be considered that the change of mesophyll cells mentioned above should be related to the enhancement of photosynthetic function of leaves and the change of ecological adaptation of leaf mesophyll cell structure after the cultivation environment is changed.
