Abstract
In this paper,effect of high temperature stress on leaf chlorophyll of Populus tomentosa seedlings was studied.The results showed that,at 30℃ and 35℃ processing,chlorophyll content in leaves of Populus tomentosa seedlings had little change.At 40 ℃,total chlorophyll decreased,in the 24～36 h,chlorophyll content appeared small increasing,then,sharp declined.
