Stock size affects early growth of a loblolly pineThis article is part of a larger document. View the larger document here.
For decades, forest researchers in the South have known that early gains in survival and growth of loblolly pine (Pinus taeda L.) can be achieved by planting large-diameter seedlings (South 1993; Wakeley 1949). For P. radiata, increasing size of planting stock also increases early growth of both seedlings (Mason and others 1996) and cuttings (South and others 2005). Stock is now produced from somatic embryogenesis (Grossnickle and Pait 2008). Although some landowners have paid $0.40 each for such seedlings, data on the effect of stock size on field-growth of tissue-cultured stock are lacking. Does stock size still make a difference when planting clones?
