YNOUE, Cíntia Kuwahara; ONO, Elizabeth Orika and MARCHI, Lia de Oliveira Santos. THE EFFECT OF GIBBERELLIC ACID ON KIWI (Actinidia chinensis Pl.) SEED GERMINATION. Sci. agric. [online]. 1999, vol.56, n.1, pp. 9-12. ISSN 1678-992X. http://dx.doi.org/10.1590/S0103-90161999000100002.
To evaluate the effect of gibberellic acid on seed germination of Actinidia chinensis Pl, kiwi seeds were removed from ripe fruits, washed and dried in the shade. The following treatments were imposed: T1 - stratification (5oC for 2 weeks); T2 - control; T3 - 50 mg.L-1 of GA3; T4 - 100 mg.L-1 of GA3 and T5 - 150 mg.L-1 of GA3. During the first week, the substrate in treatments T3, T4 and T5 was moistened with GA3. The most effective treatment to increase the percentage of germination and reduce the average medium time of germination was 150 mg.L-1 GA3.
