Grapevine Planting Stock
Quality Attributes of Grapevine Planting Stock
Once the dormant vine stock has been received, the vines should be checked to be sure they are in good condition and the roots moist. Healthy roots should feel firm, not spongy or hard and brittle when squeezed. Dissection of a few sample vines from a batch is a useful way of detecting advanced infections with trunk disease pathogens, but early-stage infections are not visually detectable. Healthy rootstock wood is a creamy color and scion wood is usually cream or green. There should be no dead tissue. Brown streaking in the wood of the rootstock or scion indicates that the vine has been infected with one or more of the trunk disease fungi.
