It is an ancient species in its own genus and well-adapted to drought environments with fissurate growth and summer dormancy. Methods We selected Dengkou as our research site and collected three stages of P. mongolica (before, during and after fissuration) during August 1-5, 2002 and 2003. We used PV technique and measured several water relations parameters (φ,φ, ROWC, RWC,△(subscript φ),ε etc. in different stages of fissurate growth for comparison and analysis of drought tolerance and its mechanisms. Important findings Different stages of P. mongolica had different abilities and pathways to maintain turgor pressure. Fissurate growth decreased the species' drought tolerance and involved multiple adaptations to drought.

The batch seeded isothermal desupersaturation experiments of SPM in aqueous solution were carried out and the overall crystal growth kinetics parameters were determined by the nonlinear optimization techniques. Assuming that the volume diffusion rate at growth is equal to the mass transfer rate at dissolution under the same conditions, the two-step crystal growth rate parameters can be determined. At the fow supersaturation, the surface integration rate is proportional to relative surface supersaturation.

通过测量螺旋霉素均相成核动力学，获得了表面能的值，估算出表面熵因子的值在1.41～1.56之间，从而可以推断出螺旋霉素晶体生长的表面反应速率同表面相对过饱和度成线性关系，这种生长机理同第四章得到的结果是相吻合的；利用估算的表面熵因子的值，把螺旋霉素晶体看作为简单的立方科瑟尔晶体，根据能量最低原理，对螺旋霉素的晶体生长进行了模拟。
