CROSS INOCULATION STUDIES IN Casuarina equisetifolia

Abstract

An experiment was conducted to identify effective Frankia strain that established good nodulation for higher biomass production in Casuarina equisetifolia through cross inoculation of Frankia strains from four different hosts viz, C. junghuhniana, c. cunninghamiana, Alnus nephalensis and Myrica gale. The result of plant biomass production and nodulation assay revealed that the superior performance of C. Junghuhniana source over other sources tested; on the other hand A. nephalensis and M.gale showed nil performance, but C.cunninghamiana source average performance over control.
