Response of Different Types of Cuttings of Seedless Lemon to Indole Butyric Acid Levels on Propagation, Germination and Growth

The present study was aimed to adjudge the growth and success of different stem cuttings of lemon to different IBA levels. Plant Growth substances provided exogenously have been shown to assist in stimulating good and early root development in cuttings. Most likely, indole-3-butyric acid is the greatest substance for widespread usage since it works well in and is safe for plants to use at a variety of concentrations to rooting and success. The experiment was conducted at Fruit Research Station Imaliya, Department of Horticulture, JNKVV, Jabalpur (M.P.), India in 3 x 4 Factorial Randomized Block Design (FRBD) consisting of 12 treatments with 3 replications. Factor – A had three levels of cuttings (hardwood, semi hardwood, softwood cuttings and factor – B had four levels of IBA (0, 2000, 3000 and 4000 ppm). Citrus limon (L.) can be propagated successfully through stem cutting. Hence, this experiment was conducted to find out the effectiveness of IBA levels on the growth and success of cuttings. Among factor-A, Hardwood (A1) showed significantly better results and soft wood (A3) showed low performance. Among factor- B, IBA @ 3000 ppm showed significantly better results and IBA @ 0 ppm showed the lowest performance. However, treatment combination T4 (Hardwood cutting + IBA @ 4000 ppm) showed the maximum sprouting percentage (96.67 %), shoot length (4.90 cm, 5.77 cm, 6.07 cm, 7.13 cm), number of leaves (11.20, 14.63, 18.17, 21.87) at 30, 60, 90 and 120 days respectively with maximum per cent success (90.00 %, 86.67 %, 83.33 %) at 60, 90, 120 days respectively, number of adventitious roots (17.30), longest root (19.34 cm). While lowest performance on growth and success was obtained in T12 (Soft wood cutting + IBA @ 4000 ppm).
