Abstract

Ground orchid (Spathoglottis plicata Blume) is an ornamental plant widely loved by the public because it has a beautiful shape, color and flower arrangement. Triggers S. plicata production decline one of them is caused by fusarium wilt caused by the fungus Fusarium oxysporum (Fo) and until now still can not be effectively addressed.Using cultivar of S. plicata which is resistance to Fo expected to be alternative in controling disease. Research of influence of resistance ground orchids are resistance to Fo had been carried out in vitro in solid medium Vacin & Went (VW), addition by fusaric acid at a concentration of 10 ppm, 20 ppm, 30 ppm and 40 ppm were compared to control (0 ppm). Spathoglottis plicata Orchid result of Fusaric acid selection subsequently inoculated wit Fo. This research has aims to determine the thickness of lignin in xylem tissue and stomata on the leaf of Spathoglottis plicata planlets results induce resistance to Fo. The research was conducted at Tissue Culture Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung. The study used a complete random design. Data of variance was analysis by ANOVA and if result diferent significanly it can be continued to LSD test 5% significant level. The results showed that increasing the concentration of fusaric acid, it also rises the thickness of the lignin and stomatal index on ground orchid plantlets resistant Fo. At the concentration of 40 ppm, the higest thickness of lignin and stomatal index were 10.33 ± 4.44 μm and 13.4 ± 1.63
