朱顶兰红斑病的研究 (Ⅱ)寄主范围及危害状

On the Red Spot of Amaryllis vittata (Ⅱ): Host Range and Disaster Symptom

朱顶兰红斑病病菌为Stagonospora curtisii(Berk.)Sacc.经接种试验和调查表明,此菌除危害朱顶兰外,还危害君子兰属的君子兰,文殊兰属的文殊兰,蜘蛛兰属的水鬼蕉,石蒜属的忽地笑、长筒石蒜、换锦花、夏水仙、中国石蒜、红蓝石蒜、石蒜、麦杆石蒜以及水仙属的水仙,总计危害6个属13种植物(包括孤挺花属的朱顶兰)。S.curtisii病菌在不同的寄主植物上呈现的症状有所不同,作者将其归纳为两类:一类呈现红斑,如朱顶兰、君子兰、水鬼蕉被害呈现圆形或纺缍形的红斑;另一类呈现褐斑,如文殊兰、忽地笑、水仙被害呈现褐斑或褐色条斑。

The fungus of the red spot is Stagbnospbra courtisii (Berk.) Sacc. The inoculation test and investigation showed that it parasitized plants of 6 genera, 13 species, which were Amaryllis vittata, Clivia miniata, Crinum asiaticum, L.var. sinicum, Hymenocallis americana, Lycoris aurea, L. chinensis, L. haywardii, L. longitubr, L, radiata, L. sprengeri, L. squamigera, L. stram-inea and Narcissus tazetta. The fungus attacked Amaryllis, Clivia and Hymenocallis, on which it could cause a red spot. The same fungus attacked Crinum, Lycoris and Narcissus too, on which the disaster symptom was brown spots.
