Improved Clonal Propagation through Rejuvenation of Mature Branch Cutting of Four Important Acacia Species

Asexual propagation techniques for producing good quality germplasm breeding and dissemination purposes have proven difficult acacia species comprised of mature planting material. The study was conducted to the effect rejuvenation on rooting ability cuttings. Shoots were induced from lower branch by cutting a part crown leaving it horizontally bench under misting system. harvested further used as stem cuttings evaluate their through application hormone. is highly variable among species. percentage sections juvenile shoots similar Acacia mangium Willd. (88%) auriculiformis A.Cunn. ex Benth. (90%). Only 52% able produce crassicarpa Benth., followed aulococarpa with only 31%. Overall, A. rooted better recorded highest mean value all traits tested. Hormone treatment significantly enhances mangium. However, did not respond well treatment. Rejuvenated than cuttings, tested in species, or without hormone Results indicated that possible rejuvenate bud break controlled environment.
