Mycobial contamination of seeds of quinoa Chenopodium quinoa WILLD during storage with special reference to presence of aflatoxins

Abstract

The seasonal occurrence of fungi were varied in different seasons. Seasonal variation affect growth and yield a crop, primarily by changing its phenological development process. The fungi bring about the chemical changes in seed, increase respiration rate of seed after contamination. Seed quality play an important role in establishment of health crop stands. The aim of the study was investigate the mycoflora associated with quinoa (Chenopodium quinoa Willd.) seeds collected from different seasons (winter, summer and rainy). Quinoa seeds collected from 5 different places (Agra, Mathura, Noida, Ghaziabad, Aligarh) of U.P. region were studied of occurrence fungi during 3 seasons i.e. winter, summer and rainy. In all 25 fungi were isolated by using ISTA techniques. The maximum occurrence of mycoflora was obtained during rainy season but more decreased during winter and summer season. newline
