Isolasi cendawan endofit pada tanaman padi serta potensinya sebagai pemacu pertumbuhan tanaman

Abstract

Studies on endophytic fungi have been increasing recently due to its potency to promote plant growth and induce plant tolerance to pests and diseases. The research was undergone to isolation and evaluation of endophytic fungi from rice in Bali. Isolation of endophytic fungi was based-on a surface-sterilized method using alcohol and NaOCl on PDA media. More than 15 isolates were successfully isolated and the selected isolates were subjected to in vitro assay for their ability to produce antibiotics and promote plant growth. The result showed 3 isolates from midrib, 3 isolates from stem, and 1 isolate from leaves of nonpathogenic endophytic fungi had plantgrowth activities. The result of endophytic fungi identification, showed isolates from midrib and stem rice namely Phoma sp., isolates from leaves namely Acremonium sp.. This indicated that some of the nonpathogenic endophytic fungi have the potency as an inducer of plant growth
