Abstract
Since the discovery of natural plant rooting hormones for propagation (Thimann and Went, 1934), it has been intuitive to apply these substances to the basal end of cuttings to produce new roots.
Basal methods used are the Quick Dip and Basal Long Soak Methods, using rooting solutions, and the Dry Dip Method, using rooting hormone powders.
Currently, many growers use foliar applied aqueous IBA rooting solutions to propagate annual, perennial and woody plants.
Dr.
Fred Davies physiology research proved efficacy of the application (Davies, 1978, 1980, 1982). Since indole-3-butyric acid (IBA) is a natural rooting hormone (Epstein, 1984, 1993), having such ability is understandable.
When aqueous IBA solutions are applied to the leaves of cuttings, the IBA enters the plant’s vascular system through open stomata.
Indole-3-butyric acid then translocates, by polar transport, to the basal end; there, plants store it for self-regulated root formation.
Kees Eigenraam (1985) developed commercial foliar methods, first used by Dutch chrysanthemum growers.
Kees and I standardized the techniques, the foliar Spray Drip Down and Total Immerse Methods.
In the early 1990s we introduced the methods to USA growers, first for annual and perennial plants.
Research by Bailey Nurseries expanded uses to woody plants (Drahn, 2007). Required for foliar methods, aqueous IBA rooting solutions are made using Rhizopon® AA Water Soluble Tablets and Hortus IBA Water Soluble Salts®.
Basal methods used are the Quick Dip and Basal Long Soak Methods, using rooting solutions, and the Dry Dip Method, using rooting hormone powders.
Currently, many growers use foliar applied aqueous IBA rooting solutions to propagate annual, perennial and woody plants.
