Abstract


Plant endogenous hormones involved in plant pathogen interaction process , has been widespread concern that the tests were cultivated under the two conditions in an indoor pot and field natural beet anti flu the rhizomania varieties as test materials , changes of endogenous hormones research beet yellow vein necrosis virus (BNYVV) infection and its differences in resistant and susceptible varieties rhizomania the to explore of endogenous five hormones beet resistance to rhizomania the relationship . The study results show that both indoor potted or field under natural cultivation BNYVV infection beet , resistant and susceptible varieties endogenous auxin ( IAA ) , abscisic acid ( ABA ) , ethylene (ETH) content disease earth (ground) have improved to varying degrees , cytokinin (CTK ) , gibberellin (GA) content decreased , with anti- susceptible varieties disease index correlation analysis showed that endogenous IAA the increment , iPA relative content (% of disease-free and % ) , - the relative content was negatively correlated with the disease index the ABA, ETH increase the amount of disease index was positively correlated ; seedling age of 35 days is BNYVV invade large period , the period as a critical period detection the beet hormone resistance relationship IAA , iPA in as beet resistance to rhizomania the identification and selection of the physiological indicators . In this study, the role of the hormone in the beet rhizomania from endogenous hormones virus infection elaborate and provide a theoretical basis for the beet resistant mechanism and the breeding of resistant varieties .
