烟草赤星病菌孢子萌发和侵染条件的研究

用烟草赤星病菌两个菌株进行测定,孢子在烟草叶面萌发能力最强;其次是在1％的葡萄糖溶液中;在蒸馏水中萌发最弱。在侵染试验中,用丙酮和70％酒精清洗的幼苗叶片发病加重;露天放置的烟苗较生长在温室内的烟苗发病重。在3种接种方法中,以孢子悬滴法效果最好。侵染和接种方法中的幼苗,其叶面微生物在种类和数量上均以处理的不同而有差别。

Role of Mg on Structure and Mechanical Properties in Alloy 718

The role of Mg in alloy/718 has been systematically investigated. Mg raises not only high temperature tensile and stress-rupture ductilities but also increases considerably smooth and notch stress-rupture life. Mg containing alloy 718M is free of stress-rupture notch sensitivity. Mg improves creep and fatigue interaction properties (LCF or cyclic stress rupture) at any grain size. The basic role of Mg is equilibrium segregation at grain boundaries which helps to change continuous grain beundary (5-Ni3Nb morphology to discrete globular form which has a retardation effect on intergranular fracture. Mg promotes the change from intergranular to transgranular fracture mode.

Characterization and adsorption behavior of a novel triolein-embedded activated carbon composite adsorbent

A novel triolein-embedded activated carbon composite adsorbent was developed. Experiments were carried out in areas such as the preparation method, the characterization of physicochemicai properties, and the adsorption behavior of the composite adsorbent in removing dieldrin from aqueous solution. Results suggested that the novel composite adsorbent was composed of the supporting activated carbon and the surrounding triolein-embedded cellulose acetate membrane. The adsorbent was stable in water, for no triolein leakage was detected after soaking the adsorbent for five weeks. The adsorbent had good adsorption capability to dieldrin, which was indicated by a residual dieldrin concentration of 0.204μg·L^-1. The removal efficiency of the composite adsorbent was higher than the traditional activated carbon adsorbent.

赤星菌毒素对烟草幼苗致病特性的研究

文章首先测验了3种培养液对烟苗生长的影响和赤星病菌在培养液中产生毒素的能力,据此选出查彼培养液用于产生毒素的培养。病菌在查彼培养液中生长28天后,表现出最高的毒素活性,毒素活性临界值(TWE50)为32。然后用毒素粗提液处理幼苗,以幼苗悬滴接种法为对比。烟苗在12小时内可见对毒素发生明显反应,表现为根部变褐和须根脱落,对悬滴接种的反应要到72小时后才可鉴别。毒素处理后36小时内烟苗进而萎蔫,21个品种的萎蔫程度与12小时内的根部反应趋势一致,根部反应和萎蔫的程度又同时与品种对悬滴接种的反应趋势相一致,3种反应间的吻合度平均近80％。
