Abstract:
Effect of various concentrations of IBA and semi hard wood cuttings on the performance of rooting in acid lime (Citrus aurantifolia Swingle) cv. PKM1 under mist was studied in the Horticulture College and Research Institute, Tamil Nadu Agricultural University, Periyakulam. The treatments of five IBA concentrations (500, 1000, 1500, 2000 and 2500 ppm) along with a control were prepared and treated with semi hardwood cuttings as quick dip method. The study was laid out in a Completely Randomized Block Design (CRD) with six treatments and five replications. The results revealed that cuttings treated with IBA of 2000 ppm (T5) recorded the highest values of all the traits viz., success per cent (80.72%), least number of days for sprouting (6.85 days), number of sprouts per cuttings (4.30), plant height (47.76 cm), shoot length (23.65 cm), number of leaves (43.52), root length (26.15 cm), fresh root weight (4.50 g) and dry root weight (1.80 g) followed by T4 (1500 ppm of IBA). Control (T1) (without IBA treatment) observed the lowest values of the traits like success per cent of cuttings (26.14%), longest days for sprouting (13.50 days), number of sprouts per cuttings (1.50), plant height (25.48 cm), shoot length (13.00 cm), number of leaves (22.15), root length (15.80 cm), fresh root weight (1.95 g) and dry root weight (0.85 g). It is suggested that semi-hardwood cutting treated with 2000 ppm (T5) concentration of IBA gives the overall best performance for mass multiplication of acid lime.
