摘　　要：喷施人工合成的植物诱抗剂葡聚六糖与人工发酵的真菌多糖和果胶多糖的混合物,可诱导黄瓜、番茄抗病性的增加,且混合糖的防效要好于各单剂处理。葡聚六糖与多糖混合诱导间隔期为5d时的防效最好,防效达74.6%,7d时无增效作用。Disease resistance was induced in cucumbers and tomatoes following spray application of a mixture of the synthetic plant disease resistance inducer, glucohexose, and a fungal fermentation of polysaccharide plus pectic polysaccharide. The mixture provided better disease control than either component applied separately. Maximum disease resistance induction was obtained with application intervals of 5 d and provided 74.6% control. Application at 7 d intervals did not improve control.
