Semi-hardwood cuttings of 12 citrus genotypes, including genera closely related to Citrus and somatic hybrid plants produced by protoplast fusion, were treated with root-inducing hormones. The cuttings were rooted under under intermittent mist in a greenhouse. The treatments included 1000 and 3000 ppm NAA, 1000 and 3000 ppm IBA, Rootone powder (a commercial formulation containing 2000 ppm NAA and 1000 ppm IBA), and the control. Evaluations after 6 weeks reveald that stem cuttings of the different clones responded significanty in root production to NAA and IBA treatments. The lowest concentration of NAA (1000 ppm) and the highest concentration of IBA (3000 ppm) yielded the maximum rooting percentage (75%) across all selections. Cuttings treated with NAA or IBA, both at 1000 and 3000 ppm, produced greater number of roots that were longer and thicker than those of the control. The effec of varying concentrations of NAA and IBA on root production of the cuttings was not uniform for of the experimental clones. Cuttings of Swingle citrumelo, Flying Dragon, Cleopatra mandarin, Cleopatra + Flyinh dragon (4X-somatic hybrid), Cleopatra + Swingle citrumelo (4X-somatic hybrid), and Hamlin sweet orange treated with the different growth regulator treatments produced bettre quality root systems compared with those of the untreated control. |
