Variation in Rooting Response of Different Clones of Casuarina equisetifolia

The ischolar_maining response of 20 different clones of Casuarina equisetifolia under different concentrations of Indole Butyric Acid (IBA) was studied in a factorial RBD experiment. Significant variations in ischolar_maining per cent and number of ischolar_mains were recorded among the different clones, treatments and their interactions. The variations observed in ischolar_main length were significant among the clones only and non-significant among treatments and clone-treatment interaction. The treatment IBA 4000 ppm performcd the best for all the parameters studied. The treatment increased ischolar_maining by 88.38% and number of ischolar_mains per cladode by 73.33% over control. The findings indicate the importance of including ischolar_maining ability of a clone (genotype) as an important criterion for its selection and evaluation.
