- Abstract
Root endophytic fungi are found in natural ecosystems, but little is known about their impact on plant growth. This study reports the impact of the three isolates of dark septate endophytic fungi isolated from Pulau Dua Sanctuary, Banten on its potential activity in Chinese cabbage growth. In vitro assay was performed to analyze the contribution of those isolates on the growth promotion of Chinese cabbage. The results indicate that Chinese cabbage seedlings inoculated with the Humicola sp. isolate compared to those inoculated with Aureobasidium sp. and Basipetospora sp, showed better response in plant growth and the increased biomass was two times higher. The analysis regarding the effect of pH on the growth of the plants showed a significant influence of Humicola sp.treatment on acidic-neutral but not alkaline conditions. The Humicola sp. isolate could utilize Val, Leu and Phe, but Leu was the most effectively used amino acid. The results suggest the occurrence of fungal utilization of the amino acids by the fungus and subsequent transfer of N to the host plant. In addition, three isolates of Humicola sp, Aureobasidium sp. and Basipetospora sp, can produce auxin-like compound in the liquid culture in the presence of tryptophan.
