摘  要:
对3个棉花矮秆品系的干物质积累动态进行了对比研究。结果表明:从开花期到吐絮期是3个棉花品系干物质积累的关键时期。除了茎枝干物质积累没有一致性外,3个棉花品系在叶面积、叶重、生殖器官干重和地上部干物质总量的增长动态上都表现出一致性。品系2、3的地上部干物质总量大于品系1,这也体现在了籽棉产量上。品系2、品系3的生殖器官干物质分配高峰在吐絮期,均占到地上部生物学总量的50%左右;而品系1的生殖器官干物质分配高峰在收获期,占到43.8%。

摘  要:
The dry matter accumulation in three dwarf varieties of cotton was compared and analyzed in this study.The results indicated that the stage from blooming to maturation was critical to the dry matter accumulation in reproductive organ.The leaves area,leaves weight,dry matter weight of reproductive organ and total dry matter weight of aerial part were increased with similar trend.The peak distribution of the dry matter in reproductive organ was in maturation period of variety 2 and variety 3,and it all occupied about 50% of the total biological yield of aerial part.However,the highest distribution of the dry matter in reproductive organ was in harvest period of variety 1,and it occupied 43.8% of the total biological yield of aerial part.
