STUDY ON CREATION OF IN VITRO ROOTS AND TREES IN Turnera ulmifolia PLANTS

Abstract

“Yellow alder” (Turnera ulmifolia L.) is well- known for a popular medical plant in the Americas with the uses to enhance reproductive health, treat premature ejaculation and impotence in men. Arbutin in it has an effect on whitening our skin naturally due to the ability to inhibit enzymes, which produce melanin without harm side- effects, prevent anti-aging and free radicals, tighten and smoothen skin. The extracted solution from leaves stimulates the activity of antioxidant enzymes (glutathione peroxidase, superoxide dismutase and catalase). This paper presents the results of studying on sterilizing plant materials and effects of auxin on root formation of T.ulmifolia from Americas in order to find a multiplication process to develop this plant in Vietnam. The optimum medium fomula for the root formation of T.ulmifolia is the basal MS medium supplemented with 0.7mg/l IBA. The suitable medium for them to develope at the nursery stage before growing in the mass- production is medium soil: sand: microbiological fertilizer with the ratio of 2: 1: 1.
