摘要： 本文对成龄油棕不同叶序的长、宽以及含水量进行了测定，并对其变化规律作了分析与研究。结果表明成龄油棕树种8-26叶长度呈现较为一致的变化规律，而小叶宽则呈无规则变化，各油棕树第16叶的小叶长最为接近，且各油棕树第18叶的小叶宽最为接近。叶长与宽比值无规律，变化范围在17.6-33.5之间；油棕不同叶序的叶片含水量呈现比较一致的变化趋势，均以16和18叶含水量最高，可达59.4%-64.6%，而且嫩叶总体比老叶含水量高。

Abstract: This study had measured the length, width and content of water of different leaf arrangement of oil palm, and analyzed the change rules of them. The results showed that the change rule of length of NO. 8 leaf to NO.26 leaf was accordant, while their width had not change rules. The length of NO.16 leaf and the width of NO.18 leaf were adjacent among the three oil palm tree. But the ratio of leaf length to width had not ruler, changed among 17.6 to 33.5. The change of leaf water content was consistent in different oil palm leaves. And the water content of NO.16 to NO.18 leaf was the highest, which were from 59.4% to 64.6%. And the water content of young leaves was higher than the old leaves’.
