Abstract
Xianpoguo and Sijili,Huizhou's two fine kinds of litchi,were planted in differdnt concentrations of added boric acid,urea and auxin-type growth regulators in pollen germination medium at 25℃.Results show that boric acid,urea,NAA,2,4-D and Aiduosu have a catalytic role in promoting different pollen germination and pollen tube growth,and that the promotion effect is closely related to the concentration of the added substance,with Xianpoguo showing greater effect.
