油橄榄开花很多,但结实率不高,这种现象不仅与气候、土壤等自然因素密切相关,而且也取决于它本身的生物学特性。一般地说,完全花的比例越高应该是结果越多,但实际上并非如此。例如,有些完全花比例相当高的品种,在没有异种授粉的情况下结实率很低(见 Olive bloom a lot, but the seed rate is not high, this phenomenon not only with climate, soil and other natural factors are closely related, but also depends on its own biological characteristics. Generally speaking, the higher the proportion of complete flowers should be the more results, but in fact it is not. For example, some cultivars that are quite fully flower-tolerant and have low seed setting rates without cross-pollination (see
