Abstract:
We detect the effect of soil drought stress on part physiological activities of Masson pine of different family.The dark respiration rate of Masson pine will decrease with different range of the decrease of leaf water potential.The photosynthesis rate will increase with the descendant leaf potential and soil potential,which demonstrates that Masson pine has much higher productivity of drought stress.Meanwhile,the relative plasma membrane permeability plasma will be enlarged and the membrane will be hurt more deeply when Masson pine meets with higher drought stress.The relationship between relative plasma membrane permeability and leaf potential shows significant linear correlation.
