Growth and propagation aspects of some medicinally important trees in Chandigarh, India: a review

Abstract

Seed germination improves with scarification, gibberellic acid treatments and seasonal variations in tree species viz. Aegle marmelos, Madhuca indica, Michelia champaca and Terminalia chebula. Seed scarification with hot water and conc. H2SO4 and, pre-sowing GA3 treatment significantly increase percentage germination. The Success of adventitious rooting of stem cuttings depends upon the physiological status of mother stock plant, its nutrient status and general growth conditions; type of cutting, pre-planting treatments and environmental conditions including season. Easy-to-root species have a higher concentration of promoters while difficult-to-root have more inhibitors. Strong and deep plant root system of the parent plant is essential to establish air layers in a sound condition supplying enough nutrients and required moisture.
