Effect of IBA concentrations on growth and rooting of Citrus limon cv. Pant Lemon cuttings

An investigation was undertaken to study the effect of different concentrations of IBA on growth and rooting of Citrus limon cuttings under Garhwal region. The hardwood cut tings of Citrus limon cv. Pant Lemon were collected from healthy vigorous shoots of 3-5 year old plants. The cuttings were planted in one kg capacity polythene bags containing soil, sand and FYM mixture in 1:1:1 (v/v) ratio. The stem cuttings of Citrus limon were treated with IBA solutions of different concentrations i.e. 1000, 1500, 2000 ppm and control (tap water only) by quick dip method. The experiment was replicated thrice with 10 cut tings in each treatment. Among all the treatments, the number of sprouted cuttings (6.29), length and diameter of sprout (23.77cm and 1.52 cm, respectively), number of sprouts, number of leaves and number of roots/cutting (17.77 and 23.00 and 52.42, respectively), and average maximum length and diameter of roots (26.33 cm and 1.33 cm, respectively) were noticed maximum in treatment with 2000 ppm concentration of IBA.
