Abstract

Potted seedling plants (SP) and micro-propagated potted plants (MP) of swallow root (Decalepis hamiltonii) were inoculated with mycorrhizal fungi (Glomus mosseae, Glomus fasciculatum and Glomus monosporum) to find out their influence on quality of tubers and their flavour content. Respective arbuscular mycorrhizal fungi (AMF) treatment in general supported better growth of SP and MP plants in terms of increased plant height, number of nodes, number of leaves, number of tubers, and fresh weight of tubers at harvesting stage. A maximum of 82.23% root specific flavour metabolite 2-hydroxy-4-methoxy benzaldehyde (2H4MB) improvement (4.5 mg g-100) was found in tubers when MP plant of D. hamiltonii was given 50 g of G. mosseae treatment, followed by 71.43 and 20% improvement of 2H4MB for G. fasciculatum and G. monosporum respectively. The novelty of the present invention is that it provides for the first time an efficient method for improvement of growth and yield of flavour enhanced tubers of D. hamiltonii by using AMF. The symbiosis of mycorrhizal fungi and swallow root would be of benefit for qualitative and quantitative improvement of this endangered and endemic medicinally important climber.
