26个油棕新种质苗期主要农艺性状评价

摘要

It was determined, the major agronomic traits, including tree tallness, stretching, new leaves, length, thickness and width of leaves, to 26 oil palm germplasm, named RYL20-RYL40 at seedling stage. And it was assessed on the performance of agronomic traits based on the 13 months' determined data. The results showed that all the oil palms germplasm had good performances and ecological adaptabilities planted in Danzhou, Hainan, comparing on that of in original country. And there is hardly any pests and disease at nursery stage.%对26个油棕新质RYLl4～RYL40幼苗期间的主要农艺性状株高、冠幅、叶片数、叶宽、叶长、叶厚度等进行13个月的连续观测，农艺性状表现评价结果表明：26个油棕新品种在幼苗期、苗圃生长期对我国热带北缘地区具有良好的生态适应性，与国外相比生长表现基本一致，且无明显病虫害。
