摘要
在内蒙古通辽及临河两个不同生态地区,研究了种植密度对甜菜光合产物分配的影响。结果表明:种植密度不仅影响同化物质在叶丛及块根间的分配比例,而且影响在叶片、叶柄间的分配。随着种植密度的增加,分配于叶丛中的干物质的比例逐渐增加,而块根中相应减少,导致生长中心转移的时期推后,其中叶丛中又以叶柄干物质的增加为甚。
Influence of planting density on assimilation products partitioning in sugarbeet was observed in Tongliao and Linhe,Inner Mongolia.The results showed that the plant density influence not only the assimilatory matter partitioning between shoot and root,but also that between leaf and stalk.The ratio of dry matter in foliage increased with the planting density,which resulted in the postpone of conversion for growth center.
