2002 NC-140 Apple Rootstock Trial: Gala Apple Trees on Supporter 4, P.14, and Different Strains of B.9, M.9 and M.26 Rootstocks Final Progress Report

摘要

The NC-140 Multi-State Research Committee has assisted tree-fruit growers with rootstock decisions for more than 35 years by evaluating performance of both old and new rootstocks in a range of climates and soils. The value of this support increases with the movement toward higher and higher density plantings, and the complexity of the decision increases with the release of more dwarfing, more precocious, higher yielding, more adaptable and/or more pest-resistant rootstock clones.
