Vegetative Propogation of Mexican Redbud, Larchleaf Goldenweed, Littleleaf Ash, and Evergreen Sumac by Stem Cuttings

摘要

Effect of cutting age (weeks after budbreak) and IBA concentration on percent rooting of Mexican redbud, larchleaf goldenweed, littleleaf ash, and evergreen sumac were investigated. Maximum predicted percent rooting was 88% for cuttings of Mexican redbud taken 4 weeks after budbreak and treated with 21 gliter⁻¹ IBA, 99% for cuttings of larchleaf goldenweed taken 6 weeks after budbreak and treated with 16 gliter⁻¹ IBA, 86% for cuttings of littleleaf ash taken 16 weeks after budbreak and treated with 17 gliter⁻¹ IBA, and 24% for cuttings of evergreen sumac taken 16 weeks after budbreak and treated with 5 gliter⁻¹ IBA.
