宁夏甘草锈病发生规律初步研究
Preliminary Research on Epidemic Regularity of Liquorice Rust in Ningxia
摘要
Abstract
Objective:Rust was one of the main diseases of artificial planting licorice in Ningxia,The research is aimed to explore the on licorice rust epidemic regularity that was not clear for a long time.Methods:Licorice rust epidemic dynamics was nvestigated by field monitoring,urediospore infection process was studied by dyeing observation,Overwintering stage was deduced by symptoms and spore germination conditions, disease transmission patterns tested by even method.Results:There were two peak period in a growing season, in the middle of June and early of September respectively.Urediospore produced appressorium after germination beside or above the pores,infected from the stomatal directly,others that not produced appressorium infected from the gland of licorice.Urediospore of Uromyces glycyrrhizae Magn.complete the infection need 68 hours at 15℃,but incubation period spend 24 days.Winter spore or mycelium that by overwintering were primary infection source of disease,urediospore spread by airflow was further infection source,disease spread in center,belongs to the multicycle diseases.Conclusion:Growth and decline regularity,disseminated cycle regularity and infection process were made clear,The result provides theoretical support for control licorice rust scientifically and effectively.关键词
