Abstract
The present investigation was conducted at Fruit Nursery, Department of Horticulture, College of Agriculture, Gwalior during the year 2015-16 on guava cv. Gwalior-27. The treatment combinations comprised with four concentration of IBA viz., 0ppm (I0), 7500ppm (I1), 10000ppm (I2) and 15000ppm (I3) and four concentration of NAA viz., 0ppm (B0), 50ppm (N1), 100ppm (N2) and 150ppm (N3). Results revealed that higher concentration of IBA (15000 ppm) and NAA (150 ppm) gave significantly highest results on callusing, number of primary and secondary roots, root weight per air layer, rooting and survival percentage over other lower concentrations while, combined application of higher concentration of both the growth regulators (I3N3) also gave higher results for all the parameters however, it was statistically at par with application of IBA @ 15000 ppm + NAA @ 100 ppm (I3N2) for all the parameters except survival percentage.
