Analysis of Phenol, Reducing Sugar, and Chlorophyll of Dendrobium sp. plantlet after induction of fusaric acid In Vitro

Orchids are ornamental plants with varied and beautiful flower colors much favored by the public. Orchid have a higher economic value when compared to other plants, both as cut flowers potted flowers. In process of growth, orchid disturbed, namely Fusarium wilt disease caused Genus which can produce toxin compound, fusaric acid is widely used in vitro selection plants. Plant resistance be formed through induction compounds. Induced an alternative way obtain disease-resistant because able create natural mechanisms. The purpose this study was determine concentration tolerant select Dendrobium plantlets optimal growth specific expression characters based on phenol content, reducing sugar total chlorophyll b. results indicated that there increase b along addition concentration.
