摘要

本文对2010年和2011年连续两年在各苗圃和植物园例行调查中发现的一种芦荟叶斑病进行了研究。症状表现为叶片背面呈圆形至椭圆形，棕色至黑色，凹陷点。调查期间仅在1 ~ 2月观察到该病。PDA上的菌落天鹅绒般柔软，深橄榄色到绿黑色。病原鉴定是利用疾病症状和显微特征进行表型鉴定的。经进一步鉴定为Cladosporium sphaerospermum Penzig，并在印度新德里IARI的印度类型文化收藏(ITCC)中得到证实。据文献报道，这是第一次报道球形枝孢霉是印度芦荟叶斑病的病原。

First report of Cladosporium sphaerospermum causing leaf spot disease of Aloe vera in India

This paper deals with the study of a leaf spot disease observed on Aloe vera leaves in various nurseries and botanical gardens during the routine surveys of two consecutive years of 2010 and 2011. The symptoms appeared in the form of circular to oval, brown to black, sunken spots on abaxial surface of leaves. The disease was observed only in January to February during the survey. Colonies on PDA were velvety, dark olivaceous to greenish black in colour. The identification of the pathogen was done phenotypically using disease symptoms and microscopic characteristics. Further investigation identified it as Cladosporium sphaerospermum Penzig which was also confirmed at Indian Type Culture Collection (ITCC), IARI, New Delhi, India. According to the literature, this is the first report of Cladosporium sphaerospermum as causal agent of leaf spot disease on A. vera from India.
