STUDIES ON CERTAIN ASPECTS OF ROOT SURFACE FUNGI. I
The present study deals with the succession of fungi on the root regions of living Pennisetum typhoides (Burm f.) Stapf. et Hubb. from July to November of 1970 and 1971. A clear succession of fungi from nonrhizosphere - rhizosphere - cortical portion of rhizoplane - steler portion of rhizosplane has been observed. The fungal population and number of species in the crown, middle and distal regions of roots in above mentioned four regions also exhibited a definite pattern. The presence and amount of amino acids and sugars in root exudates (July to October) and root extracts (July to November) have been studied. The amount of cellulose, hemicellulose and lignin components, the pH and moisture content of nonrhizosphere soils from corresponding vertical zones have been determined and the effect of root exudates of different age on 15 rhizosphere fungi has been studied.
