Abstract

The interaction between endophytic fungi and their hosts is specific, both as biological agents controlling plant diseases and plant growth promoting agents. Eight endophytics fungi was isolated from chili plants (Capsicum annum), selected based on pathogenicity tests, and were known to stimulate the growth of chili seedlings would be tested for ability to colonize the roots and stems of chili seedlings. The endophytic fungi suspension was tested with concentration of 2.8 x 106 cfu mL-1 by soaking 100 seeds in 100 mL of each endophytic fungi suspension. The application then repeated by watering 10 mL suspension of endophytic fungi on the roots seedlings area. Isolation of endophytic fungi was carried out for 4 weeks after sowing from the seedlings root and stem. The colonization rate of endophytic fungi was calculated based on the infected part of the plant and the distribution pattern of endophytic fungi on the stem was observed. The results showed that the endophytic fungus that was applied had the ability to colonize chili seeds, not only in the roots (20 - 60%), but also in the stem (20 - 40%) with the distribution pattern of colonization detected up to 3 cm from the soil surface.
