Abstract: GA4/7GA3NAA and ABA were applied to 6_year_old masson pine (Pinus massoniana Lamb.) in seedling and grafted masson pine seed orchard. The application methods were main_stem binding lanolin combined with girdling and main_stem injection. The results indicated that GA4/7 and ABA significantly promoted the formation of male strobil and GA3 also promoted it to some extent. It also showed that being combined with Girdling played a positive role.
