Effect of NAA and IAA on the Rooting of Chrysanthemum morifolium Propagated by Tip Cuttings

Chrysanthemum is the important genus of family Asteraceae.It is native to China.Globally, Chrysanthemum is a very famous flowering crop.It is valued as landscape plant as well as potted plant (Oladipupo et al., 2014).In many countries it is cultivated as a cut flower crop for commercial purposes (Baskaran et al., 2016).Now a day it is very famous in Abstract | Chrysanthemum morifolium L. cultivators in Pakistan have frequently detected that poor root cuttings of chrysanthemum caused poor anchorage of roots that results in shipping losses of these pot plants.Optimum concentration of appropriate auxins is used to promote effective rooting.Completely randomized design (CRD) is adopted and it consisted of five treatments including control and different concentration of both auxins viz.1-Naphthalene acetic acid (50 mg/L,100 mg/L) and Indole-3-acetic acid (100 mg/L, 200 mg/L) on tip cuttings of chrysanthemum.In this experiment, 15 pots of 9-inch diameter were used which were filled with silt, leaf mould and well rotten farmyard manure (1:1:1).Three cuttings in each pot and a total of 45 cuttings were planted.Cuttings of each treatment were dipped for 3 minutes in respective solution before planting.Uprooting was done after 60 days of plantation the cuttings.NAA with 100 mg/L proved best treatments that produced maximum root length, number of roots, dry and fresh weights of roots, number of sprouted buds, number of leaves, leaves fresh weight and dry leaves weight as compared to other treatments and control.This data suggested that NAA can be successfully used to increase root and shoot parameters in chrysanthemum propagated by means of tip cuttings.
