摘要
建立红松无性系种子园和实生种子园的实践证明:嫁接母树的结实株数、结实率、公顷产种量、种子千粒重等9项种实性状均优于实生母树,关键种实性状指标结实率、公顷产种量、出种率、种子千粒重、出仁率分别是实生母树的3.67倍、2.74倍、1.16倍、1.02倍和1.12倍。
Data collected from the grafting-plants seed orchard and seedling plant orchard showed the seed characteristics of Pinus koraiensis,the grafting-plants were better than those from seedling plants.The seed setting,seed production,seed purity,thousand seed weight and kernel purity from grafting-plants were 3.67,2.74,1.16,1.02 and 1.12 times higher than those from seedling-plants.
