摘要
为了解粤北地区果蔗主产区甘蔗宿根矮化病、赤条病和白条病病害发生和为害,本研究通过PCR技术对粤北果蔗产地植株蔗茎样品进行分子检测。结果表明,果蔗宿根矮化病菌总检出率为41.5%,各采样地块均检测出宿根矮化病病原菌,地块检出率达到100%,不同地块的检出率为10%~82.8%。赤条病和白条病病原菌未检出。粤北地区果蔗细菌性病害以甘蔗宿根矮化病为主。
Ratoon stunting disease(RSD), leaf scald and red stripe are three major bacterial diseases of sugarcane. In order to understand occurring of major bacterial diseases in main fruit-cane producing areas in northern Guangdong province, some local stem samples was detected by PCR. The results showed that total positive detection rate of RSD was 41.5%, and positive detection rate of RSD in plots was 100%, which ranged from 10% to 82.8% among different plots.Pathogens of leaf scald and red stripe were not found by detection, and RSD was the major disease against sugarcane in northern Guangdong province.
