Effect of IAA and NAA on the Vegetative Propagation of Aeschybanthus Sikkimensis (Clark) Stapf

Abstract

Aechynanthus sikkimensis (Clark) Stapf, an endemic epiphytic shrub of Sikkim Himalaya   with bright and long lasting flower is a potential ornamental plant. However, its habit and changes in the composition of host species have brought it to a precarious condition calling for attention towards it. Therefore, vegetative propagation with the aid of various concentrations of growth regulators like IAA and NAA were studied. Optimum concentration of both growth hormones showed a healthy result in sprouting of shoot as well as formation of root of the cuttings. Concentrations above the optimum level of both hormones proved inhibitory and brought about a reduction in all the characters under the present study.
