An attempt was made on the propagation of Guava cv. Lucknow-49 during the period of 2022-23 from apical cuttings under mist chamber conditions was undertaken. The apical cuttings were collected from shoot tips measuring about 10 to15 cm treated with different hormones of concentrations viz., IAA @ 2000, 3000 and 4000 ppm; NAA @ 2000, 3000 and 4000 ppm along with IBA @ 3000, 4000 and 5000 ppm and these were compared with control, the treated apical cuttings were planted in 40 cavity protrays and kept till 30 days for root induction under mist conditions. The different growth hormonal applications and its varied concentrations excerted a significant effect on root development in cuttings. Apical cuttings treated with IBA @ 5000 ppm was found better for rooting percentage (69.90 %), survival percentage (67.50 %), time taken to root (23.75 days), number of roots per cutting (15.15, 16.25, 17.53 and 24.64) and root length (7.33, 9.78, 13.85 and 18.33 cm) respectively at 30, 60, 90 and 120 DAP, fresh root weight (3.93 and 10.15 g), dry root weight (1.13 and 2.18 g) at 60 and 120 DAP, respectively. The rooting hormone IBA performed better in formation of rooting in apical cuttings when compared to IAA, NAA and untreated control. It can be revealed from the current study that propagation of guava through apical cuttings when treated with IBA @ 5000 ppm was proved as a better propagation method for rooting of cuttings.
