Factors Affecting the Rooting of Grape Cuttings

Abstract

When cuttings having the top bud covered by soil were compared with cuttings having the top bud exposed to air, cuttings of Tokay planted late in the spring with the top bud exposed rooted better three years out of four, having greater total rooting as well as a greater number of larger rootings (No. 1 and No. 2). The same is true for Thompson Seedless for the two years that data were collected. with AXR#1 the trend is for cuttings to roof better with the top bud exposed to air. Results with Dogridge are not conclusive. When cuttings having only the top bud were compared with cuttings having the top and bottom buds, three years of results indicate that cuttings of the common rootstocks planted in the late spring root as well with the top bud only, or better than cuttings with both top and bottom buds.
