ABSTRACT

Endophytic fungi are generally recognized as one of the important sources of novel bioactive compounds and secondary metabolites for various biological purposes. The present investigation was undertaken to document the diversity of endophytic fungi of Parkia timoriana. A total of 58 isolates belonging to 16 fungal taxa were isolated from different plant parts of Parkia timoriana. The result revealed the dominance of Aspergillus sp. in the plant parts of P.timoriana. Maximum number of endophytic fungal species was isolated from seed (6 fungal spp.) while minimum was recorded from root segment (2 fungal spp.). Total number of fungal isolates obtained was maximum in leaf and bark with 14 each and lowest in the stem and seed (6 each). Maximum infection rate(93.33%) was recorded in leaf, followed by bark (80%) and lowest in both seed and stem with 40% infection rate. Further studies on P. timorana could lead to isolation of novel bioactive compounds responsible for remedy to piles and other health problems known and used traditionally by people of north east India.

KEYWORDS: Parkia timoriana, edible legume, fungal endophyte, Aspergillus, North East India.
