Abstract

In this paper amounts of stem flow for the Quercus castaneifolia C.A.M and Acer velutinum Boiss trees were investigated during the leafy and leafless period in the campus of the faculty of Natural Resources of Tarbiat Modares University, in Mazandaran province Noor city. Stem flow was collected by spiral pipes installed at the breast height and amount of total rainfall was measured using 5 rainfall collectors at the nearest open space. Measurement of rainfall and steam flow for 4 times at leafy period with total of 114 mm and for 7 times at leafless period with total of 119 mm performed. Average amount of stem flow for the OAK and MAPLE trees were 0.64 and 5.7 percent of total rainfall respectively for the leafy period and for the leafless period 0.62 and 7.65 percent of total rainfall measured. The results showed that in both periods and both species, there was a significant positive correlation between the stem flow and the amount of rainfall. Also, according to the results of this study relationship between stem flow over rainfall for the: OAK in leafless period (R2=0.85) is stronger than leafy period (R2=0.35), whereas for the MAPLE both period of leafless (R2=0.67) and leafy (R2=0.92) period relatively strong relationship between the rainfall over stem flow observed. Generally, according to this paper for the: OAK, due to the grooved and rough skin, stem flow share of rainfall averagely 9 times more than MAPLE obtained. Although the study indicated that MAPLE is more than that of OAK produced Stem flow because was found to be highly correlated with higher bark water storage capacity as well as higher bark roughness of the OAK trees.
