Selection of endophytic fungi from Sinjai local red rice as producer of IAA (Indole Acetad Acid) hormone

Abstract

South Sulawesi, specifically Sinjai area, is an aromatic rice development area that has the potential to be developed. The applied cultivation was still traditional and based on local wisdom which was without the use of fertilizers, pesticides and other chemical drugs, so it was expected that there was a high diversity of microorganism biodiversity in plant tissues, especially endophytic fungi could produce Indole Acetic Acid (IAA) hormone. The purpose of this study was studying the potential of fungi isolates as producer of IAA hormone from Sinjai local red rice. Stages of research included macroscopic and microscopic observations of endophytic fungi and IAA hormone analysis. The fungus which had the potential to produce the highest IAA hormone was P31 BMB 16E isolate (15.17 ppm).

Endophytic Fungi in Rice Plants and Their Prospective Uses

“…The results showed that 167 isolates were IAA producers [45]. Many endophytic fungi isolated from rice and upland rice can promote the production of indoleacetic acid substances to stimulate plant growth and increase the stem length, fresh weight of stem and root, antioxidant capacity, proline, and soluble sugar content of rice plants [60,102,103] (Table 1). Note: * Antagonistic activity.…”
