Abstract
ABSTRACT Spathoglottis plicata attracts many people as an ornamental plant for parks, offices and housing complexes in urban areas. The most production constrain on Ground Orchid (Spathoglottis plicata Bl.) plantation recently has been caused by fusarium wilt caused by Fusarium oxysporum and until now still can not be solved effectively. In general, Indonesian farmers cope with fusarium wilt disease by using pesticides that often cause environmental pollution, while orchids are always physically close to the fans. Therefore, it should be an effective and environmentally friendly alternative. One of the most secure and efficient alternative diseases control for environment is by using resistant varieties. Ground orchid plantlets that are resistant to Fo have been selected by in vitro selection on Vacin & Went (VW) medium containing fusaric acid (FA) at different concentrations. The objectives of this research was to determine: Resistance criteria of S. plicata plantlet that was induced by fusaric acid on F. oxysporum infection through in vitro selection. This research was conducted at In Vitro Laboratory of Dept. of Biology, Faculty of Mathematics and Natural of Science, University of Lampung, Bandar Lampung, Indonesia. The research was compiled by using Completely Randomized Design (CRD) with one factor that is FA consisting of 5 levels: 0 ppm, 10 ppm, 20 ppm, 30 ppm, and 40 ppm on WV medium. Data analysis used ANOVA (analysis of varian) at significance level 5% and a further test with LSD (Least Significant Difference) at the significance level 5%. The result showed that: The resistance criteria of S. plicata plantlet on day 28 (0 ppm) was control and 10 ppm was susceptible. At 20 ppm and 30 ppm, its resistance criteria were moderate. At concentration of 40 ppm, its resistance criteria was resistant. Keywords: Spathoglottis plicata, Fusarium oxysporum, Induced Resistance, Fusarium wilt, Fusaric Acid
