摘要
Abstract
The effects of different treatments on cross compatibility in distant hybridization were studied in 69 cross combinations among 9 cultivars of stone fruits. The results showed that the setting percentage in balloon stage was obviously higher than that in early blooming stage. The differences of fruit set between positive and reverse crosses were significant. Female parent affected cross compatibility more remarkably than male parent in distant hybridization. The appropriate electrostatic field, He-Ne laser combined treatment with 60Co γ -ray and He-Ne laser could improve the pollen germination rate in vitro effectively, the fruit set percentage was higher than control, while 60Co γ -ray treatment reduced the pollen germination rate in vitro, and the fruit set percentage obtained by distant hybridization was lower than control.关键词
