An investigation was carried out to study the effect of rice fungal endophytes on the seed germination and seedling growth of rice at the department of Plant Pathology, SASRD, Medziphema campus, Nagaland. Culture filtrate of fourteen fungal endophytes viz. Cladosporium cladosporioides, Penicillium citrinum, Fusarium moniliforme, Trichoderma asperellum, Penicillium pinophilum, Aspergillus niger, Aspergillus flavus, Drechslera specifera, Penicillium oxalicum, Geotrichum candidum, Curvularia lunata, Aspergillus amstelodami, Talaromyces sp., and Chaetomium ochraceum were tested at different concentration (25, 50 and 100%) at different dipping periods (15, 30 and 60 minutes). The culture filtrates of the endophytes were prepared by growing the endophytes in Potato Dextrose Broth. Blotter method was used for testing the germination of seeds. The maximum per cent germination of rice seeds was recorded with the endophyte P. citrinum (96.65) when dipped for 15 and 60 minutes at 50 and 25% concentration respectively. The maximum shoot length was recorded with seeds treated with C. cladosporioides (13.74 mm) when dipped for 30 minutes at 100% concentration as compared to 6.74 mm shoot length recorded in control experiments. The maximum root length was recorded with seeds treated with A. amstelodami (42.59 mm) when dipped for 60 minutes at 100% concentration of culture filtrate as compared to control (41.19 mm).
