The Potency of Endophytic Fungal Isolates Collected from Local Aromatic Rice as Indole Acetic Acid (IAA) Producer

Endophytic fungi are fungi that live in plant tissues without causing disease symptoms and abnormalities in plants. This study aims to obtain endophytic fungal isolates from local aromatic rice and screening of their ability to produce the IAA hormone as a plant growth promoter. Totally 16 endophytic fungal isolates were isolated from aromatic rice tissue of Pulu Mandoti. Ten isolates obtained from stem, three isolates from the root and three isolates from leaf tissue. The ability of endophytic fungal isolates in producing hormones IAA varied from 0.635 to 2.651 mgl-1. Similarly, the ability to dissolve phosphate also varied from 0.005 – 3.719 mgl-1, and there is only 1 isolates that caused abnormal growth in rice seedlings.
