Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 3
Abstract
The present investigation entitled “Influence of growth regulators on the regeneration and survival of plum cv. Kala Amritsari through stem cuttings” was carried out in well maintained nursery and in laboratory of Department of Horticulture, Khalsa College, Amritsar during 2016-17. The experiment comprised of ten treatments of IBA and PHB including control, replicated thrice in randomized block design. Uniform sized 40 cuttings per replication were treated with respective concentrations of growth regulators by slow dip (24 hours) and quick dip (2 minutes) method and then planted on beds of size of 1m×1m, with 20 cuttings per bed. Results of the study showed that IBA @ 2000ppm quick dip was found to be significant in improving the shoot and root characters in cuttings with maximum shoot length (16.87 cm), 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 (T3) exhibited maximum survival percentage (77.00 %), percentage of rooted cuttings (74.33 %) and sprouting percentage (75.17 %). The treatment T3 was also found to be at par with treatment T6 (IBA 2000 ppm) with 70.67 survival percentage, 64.17 per cent of rooted cuttings and 70.67 sprouting percentage
