摘　　要：对外源GA4/7在百山祖冷杉开花促进中的应用和异花授粉实生子代遗传活力恢复效果进行了研究,结果表明,采用喷施法处理,250-500 mg/L GA4/7对15年生百山祖冷杉异砧嫁接树雌、雄球果的形成促进效果突出;GA4/7不同喷施季节对雌球果的形成未表现出显著的差异,但对雄球果的形成,GA4/7处理季节间差异极其显著,7-9月处理产生的雄球果数高出5-7月约2.5倍;依靠现有的遗传资源控制异花授粉对百山祖冷杉实生子代遗传活力恢复效果明显。Experiment on promotion of cone production by gibberelline A4/7 and filial generation hereditary vitality of Abies beshanzuensis showed that spraying 250 - 500 mg/l of GA4/7 to 15-year grafted A. beshanzuensis could evidently promote male and female cone production. Different spraying seasons had no notable influence on female cone production, but evident on male one. Treated branches during July-September produced 2.5 times cones of that during May-July. Cross pollination could restore filial generation hereditary vitality ofA. beshanzuensis.
