Abstract

Abstract: The patterns of rosin secretion from Pinus densata at Zhamu region of Tibet are studied under different air temperature and humidity.Regression analysis shows that under appropriate air temperature,relative air humidity is the main factor affecting the daily output of rosin from P.densata.Water supply is of importance to the rosin output.

Key words: Regression analysis, Pinus densata, Rosin output, Temperature, Relative humidity
