Abstracts |
To study the response of coffee seedlings to vesicular arbuscular mycorrhiza (VAM), different strains were isolated from the rhizosphere of various agroclimatic zones of Karnataka, India, where coffee is grown. Selected areas of the cities, Hassan, Chikmagalur, Mudigere and Koppa, were studied. Among 56 isolates collected, six were found predominant and they were maintained using Rhodes grass as the host plant in 1:1 sterile sand soil mixture and were screened on coffee seedlings of arabica coffee. Native VAM cultures were inoculated at the rate of 12 500 IP/plant while transplanting the seedlings into the polybags. All the 6 isolates were found to be better symbionts for coffee. However, among these native isolates, Glomus radiatum and Acaulospora myriocarpa have resulted in augmenting the plant growth. The growth parameters recorded are plant height; number of leaves; leaf area; total biomass; P uptake; acid phosphatase enzyme activity and percent root colonization. The observations indicated that Glomus radiatum has shown significant difference in increasing the biomass and also enhanced the vigour of coffee seedlings compared to uninoculated control plants. However, all the isolates have performed better than the uninoculated control plants. |
