Abstract
Present study deals with the isolation of endophytic fungi from leaf and root explants of Ananus comosus var queen from three growing conditions i.e. wild, cultivated as monoculture and cultivated as mixed cropping system with rubber plants. A total of twenty-nine endophytic fungal strains along with two nonsporulating forms were isolated from the host plant from three experimental plots. The maximum numbers of fungal strains were found belong to family Aspergillaceae and order Eurotiales. The highest rates of colonization and isolation (p<0.05) of endophytic fungi have been reported in wild foliar explants (95.53±0.53) and monoculture (1.02±0.01), respectively. The highest relative frequency was observed among isolated fungal strains in the case of Lasiodiplodia theobromae isolated from the leaf and root of wild (26.22%) and monoculture (29.62%) explants. In L. theobromae and Aspergillus flavus, isolated from the leaf and roots of wild (21.66%) and monoculture (14.66%) explants showed the highest colonization frequency. Current findings showed that the distribution of fungal endophytes and their relative frequency in host plants vary in three different growing conditions.
