Preliminary Study

Hypodematium crenatum (Forssk.) Kuhn and Anogramma leptophylla (L.) Link are threatened fern species from Western Ghats.  The present paper endorses the preliminary study on mycoflora associated with these ferns.  Eighteen fungal species have been isolated from rhizosphere and non-rhizosphere soils of selected ferns.  More diversity of fungi was observed in non-rhizosphere as compared to rhizosphere soils of both the ferns.  Aspergillus was found to be the most dominant genus among the population followed by Penicillium.  Higher percentage of fungal species is shown by H. crenatum, i.e., 44.5% in non-rhizosphere and 27.77% in rhizosphere; while a lower percentage of fungal species was found in A. leptophylla, i.e., 38.88% in non-rhizosphere and 16.66% in rhizosphere.  Number of colony forming units per gram soil was more in non-rhizosphere of A. leptophylla while it was less in non-rhizosphere of H. crenatum.  Inhibitory rhizosphere effect was exerted by A. leptophylla while H. crenatum has stimulatory effect on soil fungi.

A study was made of the occurrence of nematode-trapping fungi in the rhizosphere and on the root surface of different plants. Arthrobotrys oligospora was the predominant predaceous fungus isolated. It was almost completely absent from plant roots but occurred in varying frequency in rhizosphere soil and in root-free soil. The incidence of this fungus was consistently greater in the soybean rhizosphere and lower in the wheat rhizosphere than in corresponding soil devoid of roots, whereas for other plants, red clover, flax, etc., there was no obvious rhizosphere effect. Spore germination tests and growth of A. oligospora in root extracts of soybeans and wheat failed to account for the differences observed. However, bacterial isolates from the wheat rhizosphere were, on the whole, more antagonistic to this fungus than those from the soybean rhizosphere, whereas isolates from the latter appeared to exert a favorable effect.
