摘　　要：The white rust,caused by Puccinia horiana was one of the most important epidemic diseases on Chrysanthemum,and also was a quarantine action pest in the world.Trials determined the teliospores germinating biology of P.horiana : the teliospores were germinated between 4 ℃ and 32 ℃,while the optimum temperature range was 15 ℃ to 24 ℃,especially between 18 ℃ and 21 ℃.Water was necessary for the teliospores germination.Without free water,it couldn’t germinate in 24 h,even with 100 % R.H.The propriety of pH for germination was pH 4 to 6.5, while pH 6 was the most favorite.2 % glucose solution promoted the germination of the teliospores evidently,whereas the fresh juice of chrysanthemum foliages restrained it prominently.Light didn’t influence on the germination.The white rust , caused by Puccinia horiana was one of the most important epidemic diseases on Chrysanthemum, and also was a quarantine action pest in the world.

Water was necessary for the teliospores germination. Without free water , it couldnt germinate in 24 h,even with 100 % R. H. The propriety of pH for germination was pH 4 to 6.5, while pH 6 was the most favorite. 2 % glucose solution promoted the germination of the mum feliages restrained it prominently. Light didn＇t influence teliospores evidently, whereas the fresh juice of chrysanthemum feliages restrained it prominently.Light didn＇t influence on the germination.
