Abstract: Based on the mathematic formularization of PVcurve,it's shown that PV curve is linear whenpressure p=0.and nonlinear when p>0.At the same time,the new analysis by computer(Schulter,1988)was introduced and applied to Populus simonii data processing.The results show that at the saturated state leaf osmotic potential is 1.0512MPa,elastic modulus 1.7MPa;and at the turgor loss point,the relative water content(RWC),osmotic potential and elastic modulus are 83.5%, 1.3478MPa and 0.17MPa ,respectively,In the analysis modification,the statistic probability is 0.01 and R2reaches to 0.991. In addition,six kinds of figures of PV curves explain in detail the water relation of this woody plant.
Key words: phosphorous-rich area around Dianchi Lake, phosphate-solubilizing bacteria, chemotaxis, phylogenetic diversity.
