为给生产上选择适宜的授粉品种提供科学依据,我们从1975年开始分批对常见苹果品种进行了杂交授粉试验。试验在昌黎河北农大唐山分校果园进行,树龄为20～25年生长基本一致的23个苹果品种,分三批进行。每个品种均选一株做为杂交母树,花粉从本校果园采集。每个杂交组合做10个花序,每花序3朵花。母本树在花营膨大期进行去雄授粉套袋、挂牌。授粉后10～51天调查座果
In order to provide a scientific basis for the selection of appropriate pollination varieties in production, we conducted batch pollination experiments on common apple varieties in batches in 1975. The experiment was conducted in the orchards of Tangshan branch of Agricultural Science and Technology University in Changli, Changli, China. Twenty-three apple cultivars with the same age of 20-25 years were divided into three batches. Each species are selected as a hybrid parent tree, pollen collected from our orchard. Each hybrid combination of 10 inflorescences, 3 flowers per inflorescence. The female tree in the flower camp swelling period to go male pollination bag, listing. 10 ~ 51 days after pollination survey fruit
