摘要
持续高温抑制病菌的侵入和病斑扩展。其病害发生程度顺序为２５℃＞３０℃＞３５℃＞４０℃。温度升高，持续时间延长，ＰＯ酶活性降低，ＰＡＬ酶活性升高，表明高温增强了稻株的抗病性。
Research shows that sustained high temperature could restrain pathogenic infection and lesion spreading. The sequence of the disease occurrence was 25℃>30℃>35℃>40℃. When temperature was increasing with a longer time of exposure, Peroxides (PO) activity decreased while Phenylalanine Ammonnial Lyase (PAL) increased. The conclusion was that high temperature had reised rice's disease resistance.
