Influence of IBA and NAA on Regeneration of Stem Cuttings of Sweet Lime (Citrus Limettioides Tanaka)

The present experiment entitled “Influence of IBA and NAA on regeneration of stem cuttings of Sweet Lime (Citrus limettioides Tanaka)” was undertaken in the nursery, Department of Fruit Science, College of Horticulture, C. S. Azad University of Agriculture and Technology, Kanpur during the year 2022-23. The experiment was laid down in C.R.D. and incorporated nine treatments, each being replicated thrice. Two sets of PGRs viz., Indole-3-butyric acid (IBA), 1-Naphaleneacetic acid (NAA), each of four levels (500, 1000, 1500 and 2000 ppm) including a control were tested against the regeneration potential of stem cuttings of sweet lime. The results of the experiment signify that IBA @ 2000 ppm was influential in invigorating the shoot and root traits of sweet lime cuttings and resulted in the earliest sprouting (23.13 days) with maximum number of sprouts (7.67), percentage of sprouted cuttings (70.87%), length of sprout (10.98 cm), diameter of sprout (4.44 mm), number of leaves (20.93), length of leaves (6.35 cm), width of leaves (4.11 cm), fresh weight of shoots (24.17 g), dry weight of shoots (4.81 g), number of roots (26.27), length of roots (14.76 cm), diameter of roots (4.00 mm), percentage of rooted cuttings (70.88%), survival percentage (62.85%), fresh weight of roots (5.22 g) and dry weight of roots (1.31 g).
