Picking Early Winners Among White Pine Progeny
Abstract:After four seasons of field growth, height differences among seedlings from various seedlots of improved eastern white pine are highly significant at plantations in Connecticut, Maryland, New Hampshire, New Jersey, and New York. Survival varies from 53% to 83%, and plantation mean heights vary from 47 cm to 100 cm. Rank correlations of mean heights of seedlots at the five plantations are all positive and 8 of 10 are significant, indicating stability of performance. Two major trends show: (1) trees of a few seedlots are taller at all plantations, while those from Lake States and two Quebec seedlots grow relatively slowly wherever tested; and (2) trees of northern origin are more often taller at northern plantations, and those of central origin are taller at central plantations. North. J. Appl. For. 4:66-69, June 1987.
