一、概述又冠果是由野生纳入栽培不久的经济价值较高的木本油料树种,多用种子繁殖。因为文冠果是异花授粉植物,后代变异很大。由于种子供不应求,往往出现“见种就采,有种就播”的现象,形成了群体类型混杂,单株产量差异悬殊,单位面积产量低的状况。为建立优良品系和实现良种化,我们曾对扦插和嫁接方法进行了研究,但是由于文冠果扦 First, an overview of Crown fruit is the wild into the cultivation of high economic value of the woody oilseed species, the use of seed multiplication. Because the paper is a cross-pollination of fruit trees, offspring of great variation. Due to the short supply of seeds, there is often a phenomenon of “seeing and planting on the ground and planting on the ground”, forming a situation in which the group types are mixed and the yield per plant varies greatly and the yield per unit area is low. In order to establish good lines and achieve seed quality, we have conducted a study of cutting and grafting methods, but because of the results
