Fundamental Aspects of Auxin Foliar Spray Applications to Woody Plant Cuttings

Grants and Contracts Details


Applying auxin as a foliar spray has several advantages over traditional quick dip methods for rooting cuttings. These include potential worker safety and application efficiency. Foliar auxin sprays are also becoming an integral part of propagation systems using automated machine-assisted sticking robotics. However, not all woody species respond to foliar spray as well as a quick dip application for rooting and there are questions concerning application timing as well as the optimal number of applications. Therefore, the objectives of the proposed research will be to answer basic questions about auxin movement in cuttings related to spray volume, single vs. multiple applications, and use of a surfactant.
