Fig. 1. Leaf hydraulic vulnerability curves for eight tree species in Guandi Mountain and Heicha Mountain. A, Populus cathayana. B, Quercus mongolica. C, Ulmus pumila. D, Armeniaca sibirica. E, Populus davidiana. F, Larix gmelinii. G, Pinus tabuliformis. H, Picea asperata. The vertical lines in each graph indicate the water potential (P50) when the water transport rate is at 50% of the maximum hydraulic conductivity (Kmax). G, trees in Guandi Mountain; H, trees in Heicha Mountain.
