Abstract:
This study was conducted to identify the pathogen of apricot gummosis disease in Luntai,Xinjiang.Occurrence period and incidence rate of the disease were investigated on thespot，and symptoms of the disease were observed and described．A total of 22 infested samples at different test field were randomly collected．Pathogen isolation and purification from the samples were conducted on PDA medium using normal tissue isolation method，and the pathogen was ensured by Koch′s postulates.The pathogen was identified by morphological method and ITS sequence alignment.That was identified for the purpose of controlling and further studying the disease.The results showed that，trunks were mainly injuried by gummosis,this disease originated in middle of May，and most seriously in the latter half of the June.Apricot gummosis were physiological gummosis and infectious gummosis in Luntai.The isolated strain L9 was pathogen,the symptoms of artificial inoculation were the same as natural symptoms.The identification of Alternaria alternata was the pathogen causing the infectious gum disease of apricot in Luntai.For the prevention and treatment of infectious gummosis that should strengthen field management，and enhance trees vigor.
