Abstract
Plant cutting propagation is one of the most popular methods employed today since it is the most economical and time-efficient. Cuttings of different deciduous plants were rooted by using different concentrations of hormones known as root promoting hormones, such as indole butyric acid (IBA), acetic acid (IAA), and naphthalene acetic acid (NAA). In 2022, an experiment was carried out at the Punjab Forestry Research Institute in Faisalabad. Hormones were synthesized for the treatments in this experiment at three different concentrations i.e., 1000ppm, 2000ppm, and 3000 ppm, respectively. and the cuts' lower portion was immersed in the aforementioned solutions for five minutes. Best survival percentage i.e., 78.33% was observer through indole Acetic Acid (IAA) at 1000ppm concentration to the cuttings of Dalbergia sisso after 45 days of planting.it was observed that, (IAA) at 3000 ppm is the best concentration for Trewia nudiflora, as it shows maximum survival percentage of 65.0% on the other hand, Ehretia accuminata shows maximum survival percentage of 71.6% by treating it with Indole-3-butyric acid (IBA) at 1000ppm concentration, when we treated Terminalia arjuna cuttings with (IBA) at 1000ppm concentration it shows mean survival percentage of 78.3% on the other hand Cedreela toona showed 78.3% survival percentage when treated with (IBA) at 1000ppm concentration and ( IAA) at 2000ppm concentration after 45 days of planting the shoot cuttings.
