Effect of Growth Regulator (IBA) and Natural Substances on Root and Shoot Growth and Survival Percentage of Pomegranate Cuttings (Punica granatum. L)

Abstract

The present investigation entitled “Effect of Growth Regulator (IBA) and Natural Substances the Root and Shoot Growth and Survival Percentage of Pomegranate Cuttings (Punica granatum. L)” was carried out during the year 2021-2022 at the Department of Horticulture, Sam Higginbottom University of Agricultural Technology & Sciences, Prayagraj. The experiment was laid out in Completely Randomized Design (CRD) with nine treatments and three replications. The treatment comprises; T1- Control (water), T2- IBA @1000 ppm, T3- IBA @750 ppm, T4- Vermiwash @100%, T5- Vermiwash @75%, T6- Seaweed extract @100%, T7- Seaweed extract @75%, T8- CPP (Cow Pat Pit) @100%, T9- CPP (Cow Pat Pit) @75%. On the basis of analysis of results, it is found that T4- vermiwash@100% proved best as a potential input for different parameters recorded such as days of first shoot initiation (11), average shoot length (35.78 cm), number of roots per cuttings (38.22), number of leaves per plant (83.89), average root length per cuttings (25.55cm), average leaf area (7.01cm2 ), fresh weight of roots (7.36g), dry weight of roots (3.78g), average shoot girth (3.31cm), average shoot fresh weight (18.89g), average shoot dry weight (9.89g) and survival percentage of pomegranate cuttings in the field after transplanting (93.75%).

Effect of Hormones on Rooting of Apical Cuttings for Propagation of Guava Cv. Lucknow-49

“…The IBA @ 5000 ppm initiated better root length which could be due to hydrolysis of polysaccharides stored in these cuttings into physiologically active sugars, provides energy through respiratory activity to the root primordia that helped in rapid elongation of meristematic cells to initiate better root length [26]. Similar results were reported by Kumar et al [27] in Guava, Reddy et al [28] in Fig, Gohil [29] in Cashewnut and Tomar and Tomar [30] in Pomegranate.…”
