Soaking and Retumbling Controlled-Pollinated Scots Pine Cones Increases Seed Yields

Tree seed produced by controlled pollination is expensive, particularly when the breeding stock is high-cost introduced or exotic material. Phenological and physiological differences among genetically diverse seed sources and individuals within these sources may also decrease seed yields compared with more closely related trees. Thus, techniques to maximize seed yields of cones from controlled pollinations are worthwhile. This article describes how soaking and retumbling greatly increased seed yields from controlled pollinations on superior Scots pine (Pinus sylvestris L.) trees selected in a provenance plantation of diverse sources.
