茶树上由病毒引起的病害,印度Sharma,D.C.(1972),斯里兰卡Arulpragasam,P.A(1981)等已作报道,国内未有记录。而由类菌原体引起的茶的病害,目前国内外均未见正式报道。 1980年7月我们在海南岛定安县发现三株丛枝病株,1982年6月在华南农业大学茶园三年生茶树上见到四株同样症状的植株,当时未能找到病原。1985年起在本校茶园对8株茶芽簇生、萎缩的病株分别标记,观察其症状与病情,在各轮茶期取样进行荧光镜检测与电镜观察。此外,还赴省内各地茶场进行了病情调查。
Diseases caused by viruses in the tea tree are reported in Sharma, D.C. (1972) in Sri Lanka, Arulpragasam, P.A. (1981) in Sri Lanka, etc. and have not been reported in the country. However, the disease caused by the mycoplasma is no official report at home and abroad. In July 1980, we found three brooms in Ding’an County, Hainan Island. In June 1982, four plants with the same symptoms were seen on the perennial tea tree in the tea plantation of South China Agricultural University. At that time, the pathogen was not found. From 1985 onwards, tea plantation of eight tea buds were clustered and atrophied in the tea garden, respectively. The symptoms and the disease were observed. Samples were taken at every turn of tea for fluoroscopy and electron microscopy. In addition, went to the tea farms in the province conducted a disease survey.
