Pathogenicity test of sengon (Falcataria moluccana) seed-borne endophytic fungus

Abstract

The sengon (Falcataria moluccana) is one of the high-economic and highly cultivated industrial plants in Indonesia. Attacks by pests and diseases can affect quality and quantity and thus require effective control. One of the rare sengon plant fungus explorations has been developed. This study aims to find out the pathogenicity of 13 seed-borne endophytic fungi from sengon seeds. The result shows that seven endophytic fungi were pathogenic (Daldinia sp, Curvularia lunata, Sardiomycetes sp. Eremothecium ashbyi, Annulohypoxylon stygium. Arthrinium malaysianum, Annulohypoxylon nitens) and six non-pathogenic (Onchroconis humicola, Cladophialophora boppii, Aspergillus ruber, Aspergillus chevalieri, Ascotricha sp., and not identified fungi). Thus the isolated endophytic fungi mainly were potentially pathogenic. Among the six species of non-pathogenic endophytic fungi, O. humicola is better able to increase the increase of plumules, radicals, cotyledons, and leaves higher than six other isolates.
