Effect of Nursery Culture on Morphological and Physiological Development of Western Hemlock Seedlings
Arnott, J.T.; Dunsworth, B.G.; O’Reilly C.
1988: Vernon, CAN
Western hemlock seedlings were grown in two container sizes, subjected to short days and moderate moisture stress in July, lifted at three dates during the winter and cold stored for periods of up to four months. The influence of these cultural treatments on seedling morphology and physiology was measured. Short days effectively stopped shoot growth extension; moisture stress did not. Root growth capacity and dormancy release tests indicated a preference for lifting hemlock immediately before planting in mid March, or after two months of cold storage from a mid January lifting date.
