油橄榄(Olea europaea)引入我国后的栽培历史较短,在生产上需要解决的问题甚多。试种区一般表现开花数量多,但能正常受精结实的很少,常有90％以上的花败育不结实,对发展生产极为不利。因而如何采取有效措施,提高结实率,增加产量,是当前油橄榄生产上急待解决的一个实际问题。据报道外源激素在促进植物正常发育过程中,在一定程度上可代替正常的受精作用。据此,我们作了赤霉素和6-苄基腺嘌呤(6-BA)对油橄榄结实影响的试验,结果如下。
Olhao (Olea europaea) introduced into our country after the cultivation of a relatively short history, there are many problems to be solved in the production. The test area generally shows a large number of flowering, but can be fertilized and seldom normal, often more than 90% of flowers abortion is not strong, the development of production is extremely unfavorable. Therefore, how to take effective measures to improve the seed-setting rate and increase the output is an urgent problem to be solved urgently in the production of olive. It has been reported that exogenous hormones can promote the normal plant growth process, to a certain extent, can replace the normal fertilization. Accordingly, we made gibberellin and 6-benzyl adenine (6-BA) test on the olive fruit firm, the results are as follows.
