Abstract:: Taking the stem of Populus×euramericanacv.Zhonghuahongye?as explant，the effect of temperature and light condition on explants browning of it were studied.The results showed that low temperature pretreatment combined with simple culture medium culture could decrease browning rate and had a good browning decreasing effect；dark culture decreased browning rate effectively at the first stage and ten days was an optimum；temperature also affected browning rate，within a certain range the higher the temperature was，the more serious the browning was，and low temperature lightened browning；the light intensity in 1 000~3 000 lx could not cause an obvious effect for the browning rate.
