Rainfall event on a tree can be partitioned into through-
fall, interception loss and stemflow. In this study,stemflow was measured for 39 rainfall events in 5year-old plantations of 3 trees each, belonging toMorus alba and Grewia optiva in Dehradun, India. Diameter
of selected Morus and Grewiatrees varies from 7 to 9.3 and 8.12 to 10 cm respectively, whereas height
varies from 4 to 4.5 and 5.5 to 6.5 m respectively. Theminimum and maximum rainfall events recorded during the study period were 1.01 and 121.70mm per day respectively.
When the rainfall magnitude was lessthan or equal to 50 mm and more than 50 mm, stemflow
volume from Morus was approximately 2.72 and1.85 fold higher respectively, compared to Grewia.Maximum stemflow volume recorded for Morus andGrewia was 48,065 and 30,633 ml with respect to rainfall magnitude of 109.58 and 121.70 mm respectively.The generation of higher stemflow volume in case of Morus is due to concave orientation of branches andleaves. Results showed that a significant amountof nutrients leached from Grewia and Morus throughstemflow process.
