In vitro screening of endophytic fungi associated with mangroveas biofertilizer on the growth of black rice (Oryza sativa L. "Cempo Ireng")

Abstract

Microorganisms play an important role in maintaining soil fertility and plant health. They can act as biofertilizers and increase the resistance to biotic and abiotic stress. This study focused on the isolation and selection of endophytic fungi associated with mangrove that have ability to promote the growth of Orizasativa L. Cempoireng. Assessing the growth of plant was study in vitro test by using PDA as a media. A total of 17 fungi were found in leaf, stem and root of mangrove and classified into 6 morphotypes according to colonies characteristics and form of mycelium. The best isolate (the endophytic fungi with characteristic of white fungus colonies mycelium septa and non-septa revealed the high ability to promote the germination seed and growth of CempoIreng. Overall, the study indicated that the endophytic fungicontributed the positive effect on the growth of Oryza sativa L. “Cempo Ireng”.
