Influence of iba and phb on regeneration of Kagzi lime (<em>Citrus aurantifolia </em>Swingle) through stem cutting

Abstract

Kagzi lime propagated through hardwood cuttings with low percentage of rooting. Investigations on influence of IBA and PHB on regeneration of cuttings were carried out during the year 2017-18 at Horticulture Garden, College of Horticulture, C.S. Azad University of Agriculture and Technology, Kanpur. Minimum days to sprouting (20.64), maximum number of sprouts per cutting (5.88), maximum percentage of cuttings sprouted (17.68%), maximum length of sprouts (14.88 cm), maximum diameter of sprouts (3.28 cm), maximum number of roots per cutting (42.02), longest root (2.24 cm), diameter of root (6.24 cm), percentage of rooted cuttings (70.12%) and maximum survival percentage (82.66%) were recorded with treatment IBA 2500ppm + PHB 1000ppm (T9). The treatment with IBA 2000ppm + PHB 1000ppm (T8) recorded maximum number of leaves (21.02) and maximum leaf length (6.38 cm). The maximum days to sprouting (32.00), minimum number of sprouts per cutting (3.64), minimum sprouting percentage (11.28%), minimum (7.85 cm) length of sprout per cutting, minimum diameter of sprouts (1.98 cm), minimum number of leaves per cutting (14.40), minimum length of leaves (4.10 cm), minimum (3.20 cm) width of leaves, minimum number of roots per cutting (29.80), minimum length of root (1.10 cm), minimum diameter of root (2.57 cm), minimum (48.02%) rooted cuttings and lowest survival percentage (48.26%) were noted under control (T0).
