%X In accordance with the global climate changes, abnormal high temperature has occurred in recent years in some regions in China and the influences of such high temperature stress on tree growth have increasingly drawn attention of foresters. In this paper, provenance variation of heat tolerance in a subtropical valuable tree species, Betula alnoides, was studied. A total of 12 provenances seedlings cultivated from seeds, which were collected from Guangxi and Yunnan Provinces in China, were employed. F...
