Rooting Response of Branch Cuttings of Teak (<I>Tectona grandis</I>) as Influenced by Growth Hormones and position of the Cutting on the Crown

Abstract

The rooting response of branch cuttings of Tectona grandis (Teak) did not show significant difference of the effect of cutting position on the crown in the cuttings taken from cutting and seedling raised trees. Only hormonal treatment showed significant effects in the above case, however, cuttings taken from adult tree gave good response in both the cases (position of the cutting on the crown as well as hormonal treatment). Both IAA (Indole 3-acetic acid) and IBA (Indole 3-butlric acid) treatments promoted good rooting response in all cases. The finding clearly indicate the IDA promotes morc rooting in terms of root number while NAA (Naphthalene aeetic acid) promotes more root length.
