摘要

For rapid, easy and true to type multiplication of lemon semi hard wood cutting was taken and treated with different concentrations of NAA (1,000, 1,250 and 1500 ppm) and IBA (2,000, 2500 and 3,000 ppm) for 30 minutes with chalk powder slurry. The treated cuttings were then planted in raised nursery beds of sandy loam soil. Different observations were taken after 75 days of planting. Maximum survival (89.83%), maximum number of branches (5.08), leaves (34.30) and roots (35.66) were observed in the cutting treated with IBA at 2,500 ppm. Maximum leaf chlorophyll content (45.41 mg/100 g), stem diameter (10.64 mm) and root diameter (2.68 mm) in the cuttings were observed under same treatment. Highest average length of roots (15.83 cm), maximum root dry weight (1.48g) and shoot dry weight (22.73 g) were also observed in same treatment. Higher values of most of the characters were recorded under NAA at 1,250 ppm treatment. Besides, higher dose of IBA showed an inhibitory effect on most of the characters.
