Fruit set time had positive correlation with plant yield, the correlation coefficient was 0.5836.

结果期与单株产量呈显著正相关，相关系数为0.5836。

It is a common phenomenon that plum has plenty flowers but low fruit set, that leads to the lower yield.

李在生产上普遍存在开花量大、坐果率低的现象，严重的落花落果影响了产量，是生产中亟需解决的迫切为问题。

The results showed that the fertilization rate and fruit set rate were about 3% when peach used as female parent.

结果表明，以桃为母本，李为父本进行杂交，其受精率和结实率均为3%左右。

First, planting density should be increased and vine number be diminished to enhance fruit set, increase early yield in forcing culture.

在生产中，①早熟栽培可增加种植密度、减少蔓数，以增加果数，提高早期产量；
