Effect of Node Number and Auxin Concentration on Propagation of Ivy gourd (Coccinia cordifolia Cogn) through Stem Cuttings

Field experiment was conducted during 2010-2011 to study the effect of number of nodes per cutting and concentrations of plant growth regulators (IBA and NAA) on regeneration of ivy gourd at Indian Institute of Vegetable Research, Varanasi. Cuttings with four nodes sprouted earliest (8.8 DAP) and enhanced the sprouting per cent, length and diameter of vine, number of branches per shoot, number of leaves per cutting, length and diameter of root and regeneration per cent than one, two and three nodes per cutting. Ivy gourd cuttings treated with 75 ppm IBA took minimum days to sprout and improved sprouting per cent, increased length and diameter of vine, number of branches per shoot, number of leaves per cutting, length and diameter of root and regeneration per cent than 75 ppm NAA and 25, 50, 100, 125 and 150 ppm IBA and NAA.
