黄栀子[Gardenia jasminoidesEllis(Gardenia)]是一种重要的中药材和优良食用色素植物,湖南种植面积和产量均居全国第一。近年来普遍发生了褐色云纹斑病(简称褐纹斑病)。据在基点调查,一般株发病率为36％,个别严重地段株发病率达46％,且一旦环境条件适宜,病势蔓延很快,对生长和产量均有影响。文献上黄栀子曾有叶斑病(Pyllos-ticta gerdeuiicola)和轮班病(Pest-alotia theae)的报导,但与此病不同。为了弄清其病原,以便进行有效防治,1982年6月至1983年底,我们以湘潭县鸟石乡槐坪塘黄栀子场为基点,对病害作了调查,并进行了病原的初步鉴定工作。
Gardenia jasminoides Ellis (Gardenia) is an important Chinese herbal medicine and good food pigment plant, Hunan planting area and output rank first in the country. In recent years, widespread brown cloud spot disease (referred to as brown spot disease). According to the survey conducted at the base point, the incidence of the common strain was 36%, and the incidence of individual serious strains reached 46%. Once the environmental conditions were appropriate, the disease spread rapidly and affected the growth and yield. The literature has yellow gardenia leaf spot disease (Pyllos-ticta gerdeuiicola) and shift disorder (Pest-alotia theae) reported, but with the disease is different. In order to clarify its pathogen in order to carry out effective prevention and treatment, from June 1982 to the end of 1983, we investigated the disease based on the Huai Pingtang yellow gardenia field in Bird’s Rock Township, Xiangtan County, and carried out the preliminary identification of the pathogen .
