植物病害新鲜标本保鲜条件初探

为了探索延长植物病害新鲜标本保鲜期的最佳环境条件,选取最常见的6种代表性植物病害标本,通过对霉(粉、锈)层指数增长率、腐烂指数及杂菌率的调查,研究温度、湿度和光照对病害新鲜标本保鲜效果的影响。结果表明,延长新鲜标本保鲜期最佳的温度是2℃,最佳湿度(RH)接近100%,最佳光照条件为3000 lx以下的光强度,在此条件下,成熟度及霉层指数较适中的标本,保鲜期比常温常规条件延长5.20~11.50倍。

Primary Study on Preservation Conditions of Fresh Plant Disease Samples

To study the optimum preservation conditions of plant disease samples,six typical plant disease samples were stored in different temperature,humidity and light,and mildew exponential growth rate,corruption exponent and germ rate were observed.The optimum temperature was between 2℃,the optimum humidity was 100%,and the optimum light was under 3000lx.For plant disease samples,the best preservation condition was under 2℃,100%RH and 3000lx,which prolonged 5.20 to 11.50 times preservation time than preservation at normal atmospheric temperature.
