The results of comprehensive evaluation showed that six tree species were in the first class. They were in the sequence of Liriodendron chinense>Manjglietia yuyuanensis>Michelia fujianensis>Altingia gracilipes>Castanopsis carlesii>Tsoongiodendron odorum. These six tree species were practicable tree species for popularization in south China.展开更多
