查询词典 stem blight

Phytophthora capsici is an important fungal pathogen that causes seed rot, seedling damping-off, root and crown rot, leaf spots, stem lesions, foliar blight, and fruit rot in many solanaceous crops and cucurbits (cantaloupe, cucumber, summer squash, pumpkin, watermelon). Rottingof seedlings prior to emergence (preemergence damping-off) and blighting of recently emerged seedlings (postemergence damping-off) can occur.

3用常规PCR和实时荧光PCR两种方法对温室接种的小麦白粉病进行了检测，并在时间上与自然显症的观察进行了比较，结果表明：在温室条件下，小麦白粉病菌在接种后第5d时开始出现小麦白粉病病斑，而利用常规PCR引物XBFF/R可在接种第3d检测到小麦白粉病菌，比自然显症观察能够提前了2d检测到白粉病菌；实时荧光PCR法可在接种后1d即能检测到小麦白粉病菌，比自然显症观察能够提前了4d检测到白粉病菌，这可为白粉菌的预测或预警检测提供依据，更可为白粉病在流行前制定防治决策赢得宝贵时间。4。
