Abstract

The present investigation was conducted at the Agricultural College and Research Institute, Vazhavachanur, Tiruvannamalai to study the effect of Indole-3-Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) on the rooting of terminal cuttings of chrysanthemum. An application of growth regulators (IBA and NAA) had a positive effect on the rooting of chrysanthemum terminal cuttings. The result of the experiment revealed that the treatment of IBA @ 400ppm significantly increased rooting percentage (89%), length of roots (5.67 cm), root spread (39.18 cm), number of roots (22.67), fresh weight of roots (4.94 g), plantlet weight (1.17 g), and plant height (8.87 cm) followed by NAA @ 400 ppm (79.33%), while minimum rooting percentage (47) was observed in control. It can be concluded that the treatment of IBA @ 400ppm significantly increased rooting percentage, roots length, number of roots, plantlet weight and plant height has greater survival percentage in the terminal cuttings of chrysanthemum (Dendranthema grandiflora).
