| 摘 要： | 目的]研究板栗分子标记辅助育种的配套育苗技术，以期节约分子标记辅助育种苗木培育成本、缩短育种年限。方法]按照板栗的横径和纵径，采取1／2、．1／3、1／4等切取比例以及横切、竖切、斜切、双边竖切等切取方法，共计10个处理。测定各处理的发芽率、成活率及苗木形态指标，分析各处理与对照之间的显著性差异。结果]1／3斜切为最佳切取方式，不仅可以保证高发芽率、成活率，且经其处理后的幼苗生长状况与对照的板栗幼苗无明显差异，苗木质量较高。结论]该套育苗技术，不仅可以节约育苗成本，缩短育种年限，还可促进板栗提前发芽，对生产有一定的指导意义。

| Abstract: | Objective] The paper aimed at studying the supporting technology of Castanea mollissima Blume molecular marker-assisted selection to decrease the cost and reduce time for chestnut nursing. Method] To find the best cutting method, 10 kinds of treatments were designed according to transverse diameter and vertical diameter of the chestnut including different cutting ratios in 1/2, 1/3, 1/4 and different directions about cross cutting, vertical cutting, bevel cutting and two side-cutting. The germination rate... |
