本文研究了大豆不同叶肉组织中光合产物淀粉的积累和动用,结果表明淀粉在不同叶肉组织中的积累和动用有一种较严格的区隔化(Compartmentation)、日间变化及季节性和随叶龄变化的趋势:第一层栅栏组织细胞在整个生育期都呈“昼积夜出”的变化;第二层栅栏组织及海绵组织在鼓粒期以前基本处于长期积累而很少动用的状态,只是到了鼓粒期以后才被动用;淀粉积累和动用的严格区隔化作用只有在长成叶中表现才最明显,在具有三层以上栅栏细胞的叶片中其多出的一或两层细胞的淀粉积累动用情况与其原母细胞的相同。
In this paper, the accumulation and utilization of photosynthetic starch in different mesophyll tissues of soybean was studied. The results showed that there was a stricter Compartmentation of starch accumulation and utilization in different mesophyll tissues. The changes of daytime and seasonality with leaf age The trend of change: the first layer of palisade tissue cells showed “daytime nocturnal” throughout the growth period; the second layer of palisade tissue and sponge tissue in the drum before the basic accumulation in the long-term and rarely used state, but It was only used after the druing period; the strict compartmentalization of starch accumulation and utilization was most pronounced only in the growing leaves, with more than one or two layers of cells in leaves with more than three palisade cells Starch accumulation and utilization of its original cells the same.
