Effect of Growth Regulators on Rooting of Cuttings in Plum Cv. Kala Amritsari

Abstract

1200 cuttings made from the trees of Plum cv. Kala Amritsari were planted in 60 beds of size 1×1m., with 20 cuttings on each bed. Uniform sized 40 cuttings per replication were treated with ten treatments of IBA and PHB growth regulators by slow dip (24 hours) and quick dip (2 minutes) method before planting along with control. Results showed that IBA@2000ppm quick dip was found to be significant in improving the shoot and root characters in cuttings with maximum shoot length (16.87cm), average shoot girth (0.46cm), shoot number (4.22), fresh weight of shoots (6.82), dry weight of shoots (1.43g), leaf number (154.28), average leaf area (305.79 cm2), root number (44.90), average root length (10.88cm), length of longest root (13.5cm), fresh weight of roots (1.52g), dry weight of roots (1.09). While the cuttings treated with slow dip of IBA 150 ppm exhibited significant survival percentage (81.00%), percentage of rooted cuttings (74.33%) and sprouting percent (75.17%).

Effect of Indole-3-Butyric Acid (IBA) on Hardwood Cutting of Grapes (Vitis vinifera L.) cv. Pusa Navrang

“…This might be due to the treatment's strong root system, which returns enhanced nutrient absorption and increases fresh and dry weight of roots. Others have reported similar findings, Narula [30] in plum cv. Kala Amritsari, Kaur et al [12] in fig, Chakraborty and Rajkumar [17] in grapes, Rolaniya et al [7] in grapes, Siddiqua et al [19] in dragon fruit, Isci et al [15] in Ramsey American grape rootstock, Rajamanickam and Balamohan [28] inpomegranate Singhetal.…”

​Regeneration of Stem Cuttings of Pomegranate cv. Bhagwa as Influenced by PGR’s and Planting Time

“…Polat and Caliskan (2009) reported that IBA 1000 ppm improved root characteristics. The better rooting in cuttings treated with auxin might be due to the enhancement in hydrolysis activity which favours the formation of high carbohydrates and low nitrogen and leads to the increment in root formation (Narula 2018). The findings are in line with Kumar et al (2004) in lime and Tripathi and Shukla (2004) in pomegranate and Husen (2008) in Dalbergia sissoo.…”

Evaluation of IBA Labels on Vegetative and Rooting Performance of Dormant Cuttings of Plum Cv Santa Rosa under Mist

“…Among all these factors auxins play important role in rooting regeneration of stem cutting of fruit plants (Canli and Bozkurt, 2009). In a study Narula (2018) reported that stem cuttings of Kala Amritsari plum regenerate maximum shoot and root growth in 2000 ppm IBA treatment among all of the IBA treatments. In temperate region Santa Rosa plants grow very well but are found less successful in juvenile stage due to frost injury.…”
