Observations, suspicions, history

Similar to the discrepancies with P.2, P.22 has proven inconsistent across sites for the level of vigor control. P.22 produced size class 3 trees in Norway, but appears similar to M.27 in US trials. P.22 is a good cold tolerant option for growers with vigorous scion cultivars, rich soils, and intensive management. Overcropping of young trees must be avoided, and trickle irrigation is highly recommended to avoid drought stress. P.22 is a direct and strong competitor for the market niche presently dominated by M.27. Tree size on P.22 is uniform within individual sites.
