The effects of narciclasine isolated from Narcissus tazetta bulb on the growth of two model microorganisms, E.coli and Ceteuisiae fermentum, were studied in this paper. The results revealed that the growth of Ceteuisiae fermentum was obviously inhibited by 20μ.g/mL NCS. The inhibition was about 51%. However, the inhibition of NCS to E.coli growth was hardly observed.

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.
选取内蒙古磴口县境内具有绵刺群落的草原化荒漠区为研究样区,于2002~2003年每年8月1~5日采集未劈裂、正在劈裂和已劈裂植株,运用PV技术对不同劈裂生长状态绵刺的多种水分关系参数φ(下标 s、φ、ROWC、RWC、△、ε进行了测定,从绵刺保持膨压的能力和途径两方面进行了深入探讨;同时结合同一项目研究中绵刺劈裂生长过程中抗氧化酶系统和内源激素方面的研究成果,综合分析并探讨了绵刺劈裂生长的发生机理及其环境适应性。

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。

The feeding regimes, including optimum feeding frequency, diel feeding rhythm, and optimum feeding rate, were established for gibel carp . The optimum feeding frequency for gibel carp was determined through 8week growth trial at five frequencies (2, 3, 4, 12 and 24 meals/d). Diel feeding rhythm of gibel carp was investigated by 24-hour trials at two body sizes (mean body weight: 20.5g and 76. 3g). The optimum feeding rate for gibel carp was estimated by the bioenergetics modelling and the validation trial was carried out based on the the feeding regimes of gibel carp.
