Propagation of Dioscorea Floribunda Mart.& Gal. by Air Ground Layering

Abstract

An attempt was made to find out the possibilities of successfully utilizing air and ground layering either with or without the aid of plant growth regulators, as the means of propagation of D. floribunda. The application of NAA in 100 ppm concentration was found to be most effective, in which 90.0% and 80.0% of the treated nodes rooted in case of air and ground layering, respectively. The time taken for the initiation of roots with this treatment was least. The formation of shoots with 100 ppm NAA treatment was 70.0% and 44.0% of the total layers in case of air and layering, respectively.
