THE GROWTH AND DEVELOPMENT OF FUNGUS PHOMOPSIS HELIANTHI M. ON DIFFERENT NUTRIENT MEDIUM
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2018, Vol 10, Issue 5
Abstract
The aim of the study was to study the effect of nutrient media on the growth and development of the fungus Phomopsis helianthi. The results of studying the effect of nutrient media on the growth and development of the fungus Phomopsis helianthi and the formation of pycnidia are presented. The growth of the pathogen mycelium took place on various media: potato-glucose agar, sunflower agar, oatmeal agar, Czapek's medium, carrot agar, bean agar, and hungry agar. The intensive growth dynamics of Phomopsis helianth fungal colonies is marked on potato-glucose agar, oat agar and sunflower agar. The diameter of the colonies on the 11th day of incubation was, respectively, 80.5, 79.0 and 70.75 mm. The type of nutrient medium used significantly influenced the color of the colony, the culture characteristics and the structure of the fungus. Nutrient medium affects the formation of morphological structures and cultural characteristics of the fungus Phomopsis helianthi, in particular, the formation of pycnidia. The most intense pycnidia of the fungus was formed on carrot agar: an average of 12.3 pieces. / sm2 area of the substrate. Pycnidis did not form on hungry agar.
