| Abstract: | A study on ecophysiological characteristics of Populus albavar.pyramidalis, P.nigra var.thevestina, P. euphratica and P. pruinosa has been made in this paper.It has concluded some results with many methods of measurement,such as P-V curves and comparison of water holding ability.According to the parametes of P-V curves and the values of water holding ability,the ability of drought resistance of P.alba var.pyramidalis and P. nigra var.thevestina (introduced species)is weaker than that of P.euphratica and P.pruinosa(native species).This is the result that P.euphratica and P. pruinos adjust the native environment for a long time. This result is more helpful and more meaningful to choose the best tree forming the oasis shelter forest and to improve the system of oasis shelter forest. |
