| 摘 要： | 对罗汉松属(Podocarpus)竹柏(P.nagi)、长叶竹柏(P.fleuryi)、罗汉松(P.macrophyllus)和大理罗汉松(P.forrestii)4种植物茎水力结构特征参数进行了测定。结果显示,4种植物平均叶面积和茎端总叶面积均差异明显;4种植物的胡伯尔值(Hv)、边材密度、导水率(Kh)、比导率(Ks)、叶比导率(LSC)没有显著差异,与其平均叶面积也没有显著的相关性,可能是由于4种植物的茎端总叶面积没有显著差异引起的。

| Abstract: | The Hydraulic properties of four Podocarpus plant,P.nagi,P.fleuryi,P.macrophyllus and P.forrestii were studied.The results showed that there were significant differences among the average leaf area of four species.However,there was no significant difference among the total leaf areas,Huber value,sapwood density,hydraulic conductivity,specific conductivity,leaf specific conductivity and the leaf area of four species;and also no significant correlation between these five parameters and their average leaf area. |
