Effect of Organic Media, Indole-3 butyric acid and colour of Polythene Wrappers on success and survival of air layering of acid lime (Citrus Aurantifolia Swingle)

Present field experiment was conducted during 2012–13 at RVSKVV, Department of Fruit Science, College of Horticulture Mandsaur (M.P.). The results revealed that the highest success in rooting percentage (94.75), callus formation (0.42cm), number of primary and secondary roots (28.40 and 100.59) respectively, length of primary and secondary roots (11.16cm and 6.07cm) respectively fresh and dry weight of roots (0.76g. and 0.22g.) respectively were recorded in T-17 (IBA 10000 PPM+sphagnum moss+ black polythene) while the minimum value of these characters were recorded under T-1 (soil + white polythene). The maximum survivability (88.77%) of air layering of Kagzi lime was noted under T-17 followed by 85.92% in T-20 (IBA 10000 PPM + vermicompost + FYM + soil + black polythene) whereas the minimum survivability of air layers (42.36%) were recorded under T-1. Similarly the highest numbers of new sprouts (10.93) were noted under T-17 followed by 10.43, 9.95 and 9.37 under treatments of T-13, T-20 and T-16 respectively. The effect of black polythene was pronounced as compared to white polythene in all characters studied.
