| 摘 要： | 以4个不同类型的水稻品种，研究穗分化期间进行不同的光周期处理对源库关系的影响。结果表明，在长日照条件下，库器官发育延缓，抽穗延迟；源器官干物质生产量下降，分配至库器官中的比例减少，大量的非结构碳水化合物滞留在源器官中；库器官发育畸形，库容量下降，库器官充实受阻。不同品种间表现有异。

| Abstract: | 4 different rice varieties were used to study the effects of photoperiods on source-sink relations during panicle initiation stage. It had been revealed that, under long-day treatments, sink organs developped slowly and heading date was delayed; the dry matter production and its partitioning to sink organs decreased; substantial non-structural carbohydrate strained in source organs; sink organs were deformative and sink capacity decreased; the filling of sink organs were retarded. |
