Abstract:
The present investigation was carried out in 2022 at the College of Forestry, Navsari Agricultural University, Navsari, Gujarat. The experiment conducted in completely random design and a factorial concept that included the rooting hormones IBA, NAA, and their combinations as one factor and second factor of cutting types along with three repetitions. Among various rooting hormone treatments, combination of IBA and NAA @ 1000 ppm + 1000 ppm concentration recorded high value of shoot length (52.96 cm), number of leaves per cutting (248.85), number of shoots per cutting (2.01) at 150 DAP, root length (42.26 cm), number of primary roots per plant (9.60), fresh weight of root and shoot (5.63 and 74.95 g plant^-1, respectively), dry weight of root and shoot (2.64 and 18.21 g plant^-1, respectively) with earlier days to sprout and days to 50% sprout (8.61 days and 13.57 days, respectively), while lower values of above all parameters were recorded in Control. Between the types of cutting, hardwood cutting recorded maximum shoot length (49.00 cm), maximum number of leaves per cutting (235.02), number of shoots per cutting (4.40) at 150 DAP, root length (25.52 cm), number of primary roots per plant (7.05), fresh weight of root and shoot (3.11 and 62.06 g plant^-1, respectively), dry weight of root and shoot (1.63 and 14.42 g plant^-1, respectively with minimum number of days to sprouting and days to 50% sprout (9.91 days and 14.86 days, respectively); furthermore, lower values of all these parameters were recorded in softwood cutting. In case of interaction effect, significantly minimum days to sprout were found in treatment combination of T₁₁: IBA 750 ppm + NAA 750 ppm with C₁: Hardwood cutting (7.84 days). Whereas, significantly maximum number of shoots at 150 DAP was observed in treatment combination of T₅: IBA 2000 ppm with C₁: Hardwood cutting (2.04). Moreover, significantly maximum root length was found in treatment combination of T₁₂: IBA 1000 ppm + NAA 1000 ppm with C₁: Hardwood cutting (44.74 cm).
