摘　　要：[目的]筛选适宜成熟度不足或芽率不稳的节瓜种子的浸种方式。[方法]以122和宝玉节瓜种子为试验材料,研究不同浸种处理对节瓜种子发芽势、发芽率、成苗率、主根长度的影响。[结果]未充分成熟或芽率不稳的种子浸种时间以2.0 h为佳;成熟度不足的种子以机械式破口处理、浸种时间为0.5～1.0 h的方式最好,其发芽率高、发芽整齐。催芽时应保持种子表面干爽。[结论]该研究为提高结瓜种子发芽率提供理论依据。[Objective]To screen the proper seed soaking method for chieh-qua(Benincasa hispida Cogn.Var.chiehqua How).[Method]With 122 and Baoyu seeds as the test materials,we researched the effects of different soaking methods on seed germination force,germination rate,main root length and seedling rate of chieh-qua.[Result]Soaking for 2.0 h for the immature seeds or unstable germination seeds was the optimal.And mechanically broken and soaked for 0.5-1.0 h were more suitable for insufficient maturity seeds,which could obtain high germiantion rate and uniform buds.At the same time,pay attention to keep the seeds surface dry while pregermination.[Conclusion]This research provided theoretical foundation for enhancing the germination rate of chieh-qua seeds.
