PURPOSE: To promote fertilization in producing hybrid rice by application of gibberellin A 4 in its flowering period. n CONSTITUTION: A hybrid rice can be produced with male sterile rice as female and another rice as male. In the flowering period, gibberellin A 4 is applied in the concentration of 1-100ppm in the form of an aqueous solution. Preferably, combined application of 10 -4 -10 -1 ppm brassinoride will improve the effect. The action of gibberellin A 4 promotes the fertilization, improving the yield of the hybrid rice. n COPYRIGHT: (C)1989,JPO&Japio |
