| dc.description.abstract | Pyrenacantha volubilis is an undomesticated plant from family Icacinaceae. It has been recently brought to limelight as rich sources of camptothecine an anti-cancer drug. Even is a potential species with a huge industrial demand for future domestication and also management for highest production technology, no attempts have been made to develop technology till date. Keeping these beneficial advantages preliminary studies on morphological characterization, pre-sowing treatments and nutrient management experiment was carried out in the College of Forestry, Sirsi during 2016-17 in Completely Randomised Design. The plant is a liana, dioecious, spiral alternative phyllotaxy, green colour inflorescence. Fruit is infructescence (1-5 fruit), drupe, ovoid shape, orange colour and dimension is 15.16 × 11.02 mm. Di-cotyledon seeds with minute pores in endocarp shows papillae structures in seed coat (tegmen) it holds the seed firmly. Variations in fruits and seed parameters were also documented. Fresh and six months stored seeds showed 100 and 50 per cent viability respectively in Tetrazolium test. Among seven pre-sowing treatments GA3 100 ppm enhanced the germination (77.30%) and vigour index (2189) over control (12% and 198). 15 fertilizers treatments were taken among them application of FYM 20 g with bio-fertilizers 5 g/plant with potting mixture (2:1:0) recorded highest plant height (119 cm), dry biomass (6.45 g/plant) and camptothecine content (31%) over the control. But application of DAP 0.5 g with organic 20 g and bio-fertilizers 5 g/plant showed highest leaves (24.17), leaf area (248.04 cm2), collar diameter (3.18 mm) and root length (38.30 cm). GA3 is the best dormancy breaking treatment, combination of farmyard manure with bio-fertilizers are the best to improve the growth, biomass and camptothecine. | en_US |
