Abstract

Chickasaw plum (Prunus angustifolia Marsh.) has the potential to be planted for windbreaks, wildlife, and for human consumption; however, reliable propagation protocols need to be established. Propagation of plants by seed using mechanical scarification treatment and stratification as well as stem cuttings using selected rooting hormone rates for Chickasaw plum were investigated. Seeds and stem cuttings of previous year’s growth were collected in Payne County, Oklahoma. Seed stratification treatments included 0, 30, or 60 d at 3°C. Mechanical scarification employed tip removal from seeds with a nail clipper. Stem cuttings were treated with five IBA rates (0, 100, 1000, 3000, and 7000 mg·L−1) in factorial combination with three collection times (May, August, and October). Scarifying the seed coat did not affect germination percentage. Non-scarified seeds stratified 60 d at 3°C had the highest germination at 31%. The time of year for cutting selection and amount of IBA rooting hormone applied was critical for rooting success. Rooting success was greatest at the highest IBA concentration when cuttings were harvested in May or August (44% and 49%), respectively.
