| 摘 要： | 以玉米为材料,通过观察不同光强下玉米幼苗叶片的显微结构,探讨光强和叶位变化对玉米叶片花环结构的影响。结果表明:在同一光强下,不同叶位的花环结构发育程度不同,在不同光强下,同一叶位的花环结构发育程度也不同。总体上,同一光强下,叶片的花环结构从1-5叶位逐步完善;而同一叶位的花环结构从200、1 300、1 000μmol/(m2.s)到600μmol/(m2.s)光强下逐步完善。

| Abstract: | The effect of light density and leaf position on the kranz structure of leaves was studied by observing the microstructure of different-position leaves of maize seedling under different light density.The result showed that the development degree of kranz structure was different under different light densities and in different leaf positions.As a whole,the kranz structure of leaves improved step by step from first to fifth leaf,and under the light densities from 200 μmol/(m2·s) to 1 300 μmol/(m2·s) to 1 000 μmol/(m2·s) to 600 μmol/(m2·s). |
