甜菜各器官同化产物的分配,以及叶丛、块根增长和糖分积累在时间上有一定顺序性,又有一定连贯性。由于块根增长和糖分积累均依赖于叶片的光合产物,因此在栽培上首先要促进叶片生长,保持和延长它的最大功能,并协调根、叶同化产物的分配。甜菜各器官间的双糖含量有一定的浓度陡度;叶柄维管束中双糖含量与块根双糖含量呈显著相关r=0.84,这是叶片积极制造糖分,叶柄积极向下运输和块根积极积累糖分的结果。
The distribution of assimilation products in various organs of sugar beet, as well as the order of leaf bundle, root growth and sugar accumulation in time, and a certain consistency. As tuberous root growth and sugar accumulation depend on leaf photosynthetic products, the first step is to promote leaf growth, maintain and extend its maximum function, and coordinate the distribution of root and leaf assimilation products. The content of disaccharides in the vascular bundles of petiole was significantly correlated with the content of disaccharide in root (r = 0.84), which was the positive factor for the manufacture of sugar, the positive transport of petioles and the positive accumulation of tuberous roots The result of sugar.
