  摘要：

  聚（Ñ δ -4- nitrobenzoyl-大号鸟氨酸）与均分子量8.0×10获得的4由单体之间反应Ñ -carboxyanhydride和氢化钠。将材料从二甲基乙酰胺溶液浸涂到铂上，并通过循环伏安法在乙腈中检查涂层的行为。通过浸入0.6-0.07％的溶液（对应于20到2层紧密堆积的α螺旋），可得到13.8至1.4 mmol cm –2范围内的4-硝基苯甲酰残基的表面覆盖率。涂覆的电极显示出i pc与扫描速率成正比。他们不表明与聚（相关反复循环伏安严重的老化现象ň Iμ -4- nitrobenzoyl-大号赖氨酸）。通过在这些多层薄膜中引入还原和氧化物质的活度系数，可以开发出模拟伏安图的表达式。

  Toxic culture filtrates produced byCalonectria ilicicola, causal agent of red crown rot of soybean

  摘要：

  Eleven soybean cultivars with different levels of susceptibility to virulent isolate SG915 of Calonectria ilicicola were examined for reaction to metabolites produced by the isolate, When the culture filtrate from isolate SG915 was applied to trifoliates from 11 cultivars, cvs, 'Cajun' and 'Asgrow 7986' exhibited reduced wilting severity. However, there was no correlation between sensitivity to culture filtrate and susceptibility to the fungal isolate. Wilting severity on cv. 'Riverside 699' was greatest when trifoliates were treated with culture filtrates from isolates SG915 (highly virulent) and C31 (less virulent). The dilution end-point for culture filtrates of virulent isolate SG915 was determined to be 1:8. Nonautoclaved culture filtrates caused complete wilt of soybean trifoliates after 36 h, but autoclaved culture filtrates demonstrated a reduced ability to wilt leaves. Electrolyte leakage from treated leaf tissues increased over time regardless of the concentrations of culture filtrate tested, The greatest electrolyte losses were observed during the initial 30 min incubation of leaf tissues. The highest concentration of culture filtrate (50%, v/v) induced more electrolyte loss than the low concentration (10%, v/v) ol control. These results suggest that toxic metabolites of C. ilicicola may be involved in disease development with leaf symptom expression.
