Abstract:
The experiment was carried out to “Effect of different concentrations of NAA (foliar spray) and different colour poly wrappers on air-layering of guava (<em>Psidium guajava </em>L.) cv. Gwalior 27” during the season of<em> Kharif </em>2016-17 at the Horticulture nursery, Department of Horticulture, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, (M.P.). Results revealed that significantly maximum rooting such as callus formation (0.44cm), number of primary roots per layer (7.46) and secondary roots per layer (9.55) and rooting percentage (61.12%), survival percentage (47.31%) and growth studies i.e. number of shoots per layer (2.17), number of leaves per layer (4.13) and length of air layer (5.49 cm)<strong> </strong>in air layers of guava was recorded with the application of 125 ppm NAA (N<sub>4</sub>). Black poly wrapper (W<sub>2</sub>) exhibited significantly maximum callus formation (0.39cm), number of primary roots per layer (6.57) and secondary roots per layer (9.21) and rooting percentage (54.79%), survival percentage (43.75%) number of shoots per layer (2.04), number of leaves per layer (4.19) and length of air layer (6.31 cm) at 60 days after layering. These parameter was also significantly maximum under the treatment combination of N<sub>4</sub>W<sub>2</sub> (NAA @ 125 ppm + Black poly wrapper) over the N<sub>1</sub>W<sub>1</sub> (NAA @ 50 ppm + White poly wrapper).
