Effects of environmental factors on sap flow in Acacia mangium
马占相思树干液流特征及其与环境因子的关系

Acacia mangium is one of the pioneer tree species of re-vegetation in degraded hilly lands in South China. Whole-tree sap flow in an A. mangium forest was measured continuously on 14 trees using Granier's thermal dissipation probe method over a period of four months. Environmental factors including air temperature, air relative humidity, soil relative humidity, photosynthetically active radiation (PAR) and global radiation were measured simultaneously with sap flow. Sapwood depth was highly correlated with ...
