Investigations on the propagation possibilities with stem cuttings of giant kingrass (Pennisetum hybridum)

Objective: The objective of this study was to examine the rooting capability of stem cuttings of giant king grass (Pennisetum hybridum). Material and Methods: Stem cuttings taken in active growing stage of the crop were kept in different periods (3, 6, 12, 24, 36, 48, 72 and 96 hours) and in media (dry and wet in closed packaging). Cuttings were immersed in different concentrations of IBA (0, 2K, 4K and 6K ppm) for 5 seconds and then planted into the soil. Some properties such as rooting rate, number of shoot and root dry weight were tested in the experiment. Results: The data obtained indicated that there were significant effects of waiting period, media and IBA concentrations on all measured characteristics except rooting rate. The prolonged waiting time and in dry media reduced the shoot length, number of shoot and root dry weight per cuttings. Conclusion: Application of 2K ppm IBA was determined as the best treatment for rooting the stem cuttings of giant king grass. © 2023 Council for British Archaeology. All rights reserved.
