摘要：

摘要：本试验以南洋红、SC124、GR911、巴西种及GR891为试验材料，分析各木薯品种光合产物蔗糖和淀粉在不同部位的分配。试验结果表明：叶片同化产物蔗糖，直接通过韧皮部的运输到达块根，在块根中通过淀粉合成酶，转化成淀粉，随着块根淀粉含量的增大，叶片、块根中蔗糖含量也有增大的趋势，随着木薯块根淀粉积累的速度增加，叶片、叶柄中淀粉含量呈逐步减少的趋势。

Abstract: Taking five cassava varieties, SC124, GR911, Baxizhong, GR891 and Nanyanghong as a test material, analyze the distribution of photosynthetic product starch and sucrose content in different position of cassava, the results showed that sucrose of assimilation product of leaves is transported to earthnut through phloem, then sucrose transform into starch with the starch synthase. With earthnut starch content of cassava adding ,the sucrose content in leaves and earthnut have increasing trend, the starch content in leaves and leaves stalks have descending trend.
