摘  要:
以来凤县漫水乡油桐基地的油桐地方品种和全国推广油桐品种贵桐2号的单株为观测对象,对其表型性状及立体因子进行了观测。结果表明,大米桐、小米桐和五爪桐是来凤县普遍栽培的当家品种,主要分布于海拔500m以下的区域。试验筛选出了的5棵树龄超过22年、生长势旺盛的地方品种金丝油桐单株,这些单株具有良好的遗传性状和适应性,是开发油桐地方品种的首选材料。与金丝油桐单株相比,贵桐2号单株分枝角度小,较适合密植;加大贵桐2号初植密度,可以使油桐产量得以提高。

摘  要:
The phenotypes and locality factors of the tung tree varieties Guitung No.2 and local traditional cultivated tung trees were investigated.The results showed that "Dami","Xiaomi" and "Wuzhua" were the main cultivated tung tree varieties,and mainly distributed the area below 500m in elevation.Five plants aged above 22 years of the local cultivated tung tree variety "Jinsiyoutong" were selected,which were the preferred variety for developing tung tree resources.Compaired with the variety of "Jinsiyoutong",the variety of Guitong No.2 was suited for close planting and planted in high population in order to obtain high output.
