Abstract:
An experiment was conducted with three plant growth regulators (IAA at 100, 300, and 500ppm concentration levels, GA3 with 50, 100, and 150ppm concentration, IBA at 1000, 2000, and 3000ppm concentrations) and a control treatment. Observations from ten randomly selected plants from each replication were recorded for quantitative characters on root induction and shoot inductions parameters. The cuttings treated with GA3 @ 150ppm (T9) took the least number of days (90 days) for the emergence of the first node while cutting treated with IBA@ 2000 (T5) took the least number of days for the beginnings of the first node, and the opposite for the first emergence of the node. Maximum leaves (22.25), the average number of roots per cutting (30.59), average number of buds per cutting (9.91), the maximum length of longest root (28.29 cm), average root formation zone (28.24cm), the maximum length of longest root (27.84 cm), an average thickness of widest roots (1.79 mm) were discovered 90 days after planting in the treatment that was treated by IBA @ 2000ppm and then by IBA @ 3,000ppm.
