Rauvolfia serpentine (Linn.) Benth. ex Kurz (Indian serpentwood), belonging to the family Apocynaceae, and popularly known as India’s wonder drug plant. It is an upright, perennating, evergreen undershrub with tuberous roots. Its dried root is the economical part which contains a number of alkaloids and some important secondary metabolites. The present study was conducted to determine the effect of arbuscular mycorrhizal fungi (Glomus fasciculatum) and some plant growth promoting rhizomicroorganisms (PGPR,s) on Rauvolfia serpentine plants under open pot conditions. Different plant growth parameters viz plant height, number of leaves, fresh weight, dry weight, mycorrhizal parameters were recorded. The results of this experiment clearly indicated that Glomus fasciculatum and plant growth promoting rhizomicroorganisms enhance the growth, biomass production in Rauvolfia serpentina plant. However future studies can be done for standardizing with different combinations of arbuscular mycorrhizae fungi and PGPRs. Key Words: Rauvolfia serpentine, Glomus fasciculatum, PGPR,s, secondary metabolites.
The term mycorrhiza is defined as a symbiotic association of a fungus and the roots of a plant. Frank (1885) defined mycorrhiza as symbiotic associations between fungi and roots that are not pathogenic. These symbiotic plant-fungus associations were required for the nutrition of both partners. Mycorrhiza form mycelium and penetrate it in between cells and inside the cells.
English: Rauvolfia /Indian snake root
Hindi: Chandrabhaga, Sarpagandha
Spicies: Rauvolfia serpentina
Description of the Plant:
Rauwolfia serpentina is a medicinally important herb (Salma et al., 2008). It is commonly known as Sarpagandha, Chandrabagha, Snake root plant, Chotachand, Chandrika and Harkaya etc (Mallick et al., 2012). The plant is growing under varying edaphoclimatic conditions in the humid tropics of India, Nepal, Burma, Thailand, Bangladesh, Indonesia, Cambodia, Philippines and Sri Lanka. In India, it is cultivated in the states of Uttar Pradesh, Bihar, Tamil Nadu, Orissa, Kerala, Assam, West Bengal and Madhya Pradesh (Dutta and Virmani, 1964).
