Abstract
With difficult-to-root cultivars, indolebutyric acid (IBA) improved the overall rooting and the numbers of usable rootings of cuttings of early-pruned vines of Salt Creek and Dog Ridge. It improved only the numbers of usable rootings of cuttings of late-pruned vines of Salt Creek and the size of the rootings of cuttings of late-pruned vines of Dog Ridge. IBA improved the size (weight) of rootings of Salt Creek.
With easy-to-root cultivars IBA improved the numbers of usable rootings of Ganzin 1 and Zinfandel and size of rootings of Ganzin 1.
Refrigeration was detrimental to the size of the rootings of cutting from early-pruned vines of Salt Creek. It reduced the total rooting, numbers of usable rootings and size of rootings of cuttings from early-pruned vines of Dog Ridge, and the size of rootings from cuttings of late-pruned vines of Dog Ridge. It was detrimental to the rooting of cuttings of Thompson Seedless, but had no effect on Ganzin 1.
