Rooting of Cuttings: Effects of Indolebutyric Acid (Iba) and Refrigeration on Rooting JF American Journal of Enology and Viticulture JO Am J Enol Vitic. FD American Society for Enology and Viticulture SP 28 OP 32 DO 10.5344/ajev.1979.30.1.28 VO 30 IS 1 A1 C. J. Alley YR 1979 UL http://www.ajevonline.org/content/30/1/28.abstract AB 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.
