RT Journal Article SR Electronic T1 High Level Grafting of Grapevines JF American Journal of Enology and Viticulture JO Am J Enol Vitic. FD American Society for Enology and Viticulture SP 35 OP 39 DO 10.5344/ajev.1971.22.1.35 VO 22 IS 1 A1 Fred Jensen YR 1971 UL http://www.ajevonline.org/content/22/1/35.abstract AB High-level cleft or notch grafts made on Vitis vinifera L. grapevines at 2 to 3 feet above the ground surface were equally successful although the notch grafts made smoother unions. Bark grafts were less successful.Notch grafts made in mid-April, about a month after bud burst but prior to bark slippage, were equal or superior to earlier grafting.Painting the scions and the black asphalt-water emulsion grafting compound with white interior latex or vinyl paints improved the success of either early or late grafts. These paints reduced moisture loss from the scion wood.
