将从马铃薯上分离获得的Ａｌｔｅｒｎａｌｉａ ｓｏｌａｎｉ菌株用０．５％的灭菌葡萄糖液配成浓度为１．０×１０５个孢子／毫升的孢悬液，用悬滴法诱导接种温室内８～９叶期ＮＣ８９烟草植株的第４、５片叶，１２天后用烟草赤星病菌对第２、３、６、７片叶进行挑战接种，结果表明，Ａｌｔｅｒｎａｌｉａ ｓｏｌａｎｉ在一定条件下可诱导烟草植株对赤星病产生系统抗性，抗性诱导效应达８６％．此外，分离自白菜、油菜、葱和丁香上的４个Ａｌｔｅｒｎａｌｉａ ｓｐｐ．菌株也可或多或少地诱导烟草植株对赤星病产生抗性．
The Alternalia solani strain isolated from potato was spiked with a 0.5% sterile glucose solution to a spore suspension having a concentration of 1.0 × 10 5 spores / ml and inoculated with 8 to 9 leaves The fourth and fifth leaves of NC89 tobacco plants were challenged with the second, third, sixth and sixth leaves after 12 days. The results showed that under certain conditions, Alternalia solani could induce tobacco plants to produce brown spot Systemic resistance, resistance-induced effects of up to 86%. In addition, four Alternalia spp isolated from cabbage, canola, onions and cloves. Strain may also induce tobacco plants more or less resistant to brown spot disease.
