摘要

木霉属包含许多种类,由于它们具有抑制病原体和增强其对土壤传播病原体的生物防治能力而具有重要的经济意义。为了充分利用木霉在特定应用中的全部潜力,精确的鉴定和表征是至关重要的。分子标记的应用促进了对不同生物制剂分离株间准确变异的分析。本研究旨在评估木霉商业产品的形态多样性。由不同公司生产并可供销售的以木霉为基础的商业产品是从阿科拉和那格浦尔市场收集的。采用TSM法从滑石粉载体样品中分离到8株菌株。通过菌落特征和形态特征对木霉分离株进行了区分。所有分离株的生长方式、菌落颜色、菌落类型、色素沉着、分生孢子大小和形状等形态特征均不同。

Morphological variations observed in Trichoderma asperellum isolated from commercial products
Genus Trichoderma contains many species that are of great economic importance because of their ability to suppress pathogens and enhance their biocontrol capabilities against soil borne pathogens. In order to utilize the full potential of Trichoderma species in specific applications, precise identification and characterization are vital. The use of molecular markers has given a boost to the analysis of the accurate variation among various isolates of bio-agents. The present study was carried out to estimate the morphological diversity among commercial products of Trichoderma. Trichoderma based commercial products produced by different firms and made available for sales were collected from Akola and Nagpur markets. A total of eight isolates were isolated from talc powder carrier based samples on TSM. The Trichoderma isolates were differentiated by colony characters and morphological features. All isolates showed different growth patterns, colony colour, colony type, pigmentation and morphological characters like phialides, conidial size and shape.
