Drought-tolerance of main tree species in Changbai Mountain

Abstract

Abstract: Global warming may result in the development of drought. To understand the response of maintree species in broadleaf-Korean pine forest at low elevation on Changbai Mountain to the predieted drought, water-related parameters were determined by PVcurve technique to evaluatethe drought-tolerance of these tree species. The species be able to tolerate drouht were put indecreasing order as following: Populus darvidiana, Quercus mongolica, Pinus sylvestris var.mongolica, Pinus koraiensis, Pinus sylvestrisformis, Betula dahurca, Ulmus Propinque,Acer mono, Tilia mandshurica, Tilia amurenses, Picec koraienses, Betula platyphylla, Abier mephrolepis, Fraxinus mandshurica, Juglans,mandshurica, Phellodendron amuremse.

Key words: Global warming, PV curve technique, Drought-tolerance, oxidation resistance, Kobresia pygmaea, K. tibetica, warming, morphology
