Abstract

Hemp (Cannabis sativa L.) has recently become legalized in the United States (U.S.). To grow hemp, often propagation occurs via asexual means through rooting vegetative tip cuttings. To produce plants, meristems are excised from stock plants and propagated to produce transplants for greenhouse or field-production. Successfully rooting vegetative cuttings can vary widely among growers due to greenhouse propagation environmental conditions, cultural inputs and practices, and vegetative cutting quality. To overcome rooting challenges, the impact of cutting stem caliper (diameter) and the use of root-zone heating (RZH) on rhizogenesis were investigated. Results indicated that large (2.9 – 3.2 mm) caliper cuttings and the use of RZH of 27.8^oC resulted in a higher quality rooted cutting.
