摘要：Four kinds of strawberry (Benihoppe, Akihime, Tuscany and Qianmei) seeds were taken as the materials, to study the effects of gibberellin in different concentrations and ultrasonic treatment on seed germination. The results showed that thousand kernel weights of seeds from different strawberry varieties had significant difference, and the sequence was Benihoppe=Akihime>Qianmei>Tuscany. Gibberellin treatment could improve germination rate of strawberry seed, and the optimal gibberellin concentrations for Benihoppe, Tuscany, Qianmei and Akihime were 5, 5, 5 and 10 mol/L. Gibberellin treatment could improve germination potential of Tuscany and Qianmei, and germination potential rose with gibberellin concentration increased within certain range, while ultrasonic treatment obviously inhibited germination of strawberry seed.
