The eco-physiological characteristics of drought endurance of Pinus sylvestris var.mongolica were studied under different climatic regions, soil water and leaf water condition.Furthemore,the response and adaptability of trees to water stress was done.The below showed the results. 1 The parameters of drought endurance of P. sylvestris var. mongolica was measure and studied by PV technology in the subhumid, semiarid and arid regions The results indicated the osmotic potentials at water saturation condition and at the initial loss turgor decreased as the climatic drought degree increased,and related linearly with the climatic moisture index.It was proved that the drought endurance of P. sylvetris var. mongolica was varible and the elevation of the osmotic adjust capability was a main way to the adaptation of trees to the drought climatic environment.

本文研究了樟子松(Pinus sylvestris var.mongolica)的主要耐旱生理生态特征在不同地区、不同土壤水分状况和叶水分状况下的变化,进而研究了樟子松对水分胁迫的反应和适应,结果如下: 1 应用 PV 技术对半湿润区、半干旱区和干旱区樟子松耐旱性指标测定研究指出,水饱和总体渗透势和初始失膨点总体渗透势随着气候干旱程度增加而增加,与气候湿度指标呈直线相关,证明了樟子松属于耐旱性可变的树种,渗透调节能力增加是其对干旱气候适应的主要途径。

以动脉血气分析做为手段,对静松灵、水合氯醛、激光三种麻醉方法进行评价,激光麻醉对实验马血气及酸碱值没有显著影响;静松灵(1mg/kg体重,im)和水合氯醛(128/100kg体重,iv)都能使PO_2、Sat·O_2、C-O_2等显著下降,但水合氯醛出现较早,在注射后30至60min时最低;而静松灵出现较晚,以注射后60~90min显著,但都未构成低氧血症,更未达呼吸衰竭。

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase(Rf0.57、Rf0.63)(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.
