Abstract

Phalaeonopsis amabilis is one type of orchid that is famous for its beauty. In its growth P. amabilis experienced problems such as the emergence of fungal pathogens. Fusarium oxysporum (Fo) is a fungus that can cause fusarium wilt in P. amabilis. Control to prevent fungal infections one of them with the mechanism of impact or induced resistance.Fusarium wilt selection can be done using Fusaric Acid (FA). This study aims to determine the effective concentration of AF to induce fusarium wilt in P. amabilis planlets and analyze the resistance of P. amabilis planlets to Fo in vitro. This study uses a Completely Randomized Design (CRD) with one factor, namely FA concentration consisting of 4 levels, namely 0 ppm (control), 20 ppm, 40 ppm and 60 ppm, each concentration is done 5 times. The results showed that the effective FA concentration to induce fusarium wilt in P. amabilis plantlet was 60 ppm concentration. The resistance of P. amabilis plantlets to Fo in vitro using FA is 60 ppm concentration because it is able to fusarium wilt disease well with resistant criteria.
