The study researched the 3～4 a trials after engrafting,the results were as follows:(1) The results of variance anaylsis indicated that there were highly significant differences in yield per plant and yield per crown projection area among clones,and the height,stem diameter and crown side were highly significant in some test sites.
在高州市大坡镇、古丁镇以及茂名市八一林场三个试点开展橄榄优良品系嫁接扩大试验,嫁接后第3,4年的结实及生长结果如下:(1)无性系间单株产果量、单位树冠投影面积产果量均达极显著差异水平,树高、径粗和冠幅在有的试点达极显著差异、有的试点无显著差异,表明无性系间结实存在着遗传差异,通过无性系测定选择的高产无性系有效。
