In Vitro Impact of Temperature on the Radial Growth of Pathogenic Fungi

Benkee Thiyam, G. D. Sharma

Abstract :

Environmental factors play an important role in the development of post harvest diseases associated with fruits. Fruits rotting fungi grow best at optimum temperature and related moisture content. The extremely high and very low temperature decreases the growth of fungi. To determine the growth rate of fungi, fungal isolates were grown in in vitro on agar. Among the various isolates, studies were conducted on the growth of most dominant five isolates Apergillus niger, Penicillium, Fusarium oxysporum, A.fumigatus and A. flavus fungi by incubating at different temperature 10,15,20,25,30,35 and 40?C for six days. This study indicated that isolated fungi were able to grown in large temperature range. However, a temperature below 10?C and above 35?C presented inhibitory effects on mycelial growth. Results revealed that optimum temperature for maximum growth, range from 25?C to 30?C.The findings suggest that storage of fruits at low temperature reduces spoilage of fruits. Controlling the storage conditions can play a significant role in reducing the growth of fruit rotting fungi.
