| Abstract: | With fresh onions and pearl meadowsweet powdery mildew asexual spores as test materials,influence of different carbon and nitrogen source,pH,temperature and light on the spore germination were studied.The results showed that the nitrogen source suited for spore germination was alanine,carbon source were sucrose and glucose.The best temperature suited for spore germination was 23℃;The best pH value suited for spore germination was 6~7;fucl expossare was best suitable for spore gemination.. |
