Variation in Rooting Response in ten Provenances of Azadirachta indica A. Juss

The ischolar_maining response of ten indigenous provenances of Azadirachta indica under the effect of different treatments viz., IAA, IBA and Thiamine was studied in a factorial RBD experiment. Signifiant variations in almost all parameters were recorded among the different provenances, treatments and their interactions. The treatment IBA 1000 ppm performed the best for all the parameters studied. The treatment increased ischolar_maining by 85.5%, number of ischolar_mains per cuttings by 240.8%, maximum ischolar_main length by 68% and ischolar_main dry wt. by 218.7% over control. The provenance Mandore, Rajasthan (P₉) showed overall best ischolar_maining response with 64.17% ischolar_maining, 9.64 number of ischolar_mains per cutting, 6.15 em maximum ischolar_main length and 0.075% gmIcutting ischolar_main dry wt. The interaction of provenance Midnapur, West Bengal (P₅) with treatment IBA 1000 ppm (T₃) gave best results in respect of number of ischolar_mains per cutting (17.67), maximum ischolar_main length (7.61 cm) and ischolar_main dry weight (0.163 gm/cutting). However, the provenance Dodaballapur, Karnataka (P₁₀) with treatment IBA 1000 ppm (T₃) gave the maximum ischolar_maining (96.67%). The findings indicate that it is desirable to include ischolar_maining ability of a provenance as an important criterion for its selection and evaluation.
