Variation in Rooting Response in Fourteen Clones of <I>Gmelina arborea</I> Roxb.

Abstract

The rooting response in fourteen indigenous clones of Gmelina arborea, under intermittent mist conditions was studied. Leafless cuttings of 1-15 cm diameter and 15-20 cm length were prepared with one of two nodes. The cuttings were treated with 0.1% bavistin for 10 minutes. The treated cuttings were given quick dip in root initiating hormone, i.e., Indole 3-Butyric Acid at 1000ppm concentration in talc base. Clone 136 showed highest percentage of rooting (85), while clone No. 130 showed the least performance (40). Significant differences were observed in rooting response among the different clones.
