Cold Temperature Tolerance of Apple Rootstock Trunk and Root Tissues
American Society for Horticultural Science
Cold hardy apple rootstocks are an essential component for survival and productivity of trees in orchards planted in regions that can be subject to severe cold stress. The series of experiments described in this manuscript test the cold hardiness properties of several recently released rootstocks and compare it to well established controls. Apple rootstock G.935 appears to be the most cold hardy of the group tested, performing much better than the cold hardy control M.26. Apple rootstock G.41 seems to be just as cold hardy as M.26 depending on experiments and quality of the material.
