    Description

    Twenty-one seed sources of Himalayan white pine (Pinus griffithii McClel.) (11 from native stands and 10 from planted trees) were studied in Maryland's State Forest Tree Nursery and in 11 plantations in Maine, Maryland, Michigan, Illinois and North Carolina. In the nursery, intraspecific variations were observed in leaf lengths, time of bud-set, tendency for secondary growth, and 2-year heights and diameters. Survival rates in Maryland's Piedmont Plateau and coastal plain, and in North Carolina were satisfactory, In Maine, New York, Michigan, Illinois and Maryland's Allegheny Mountains, P. griffithii either completely failed or showed very poor survival. Some strains from Pakistan were more winter-hardy than those from India or Bhutan. In two Maryland plantations best growth rates were attained by populations from Uttar Pradish in India, Shorgan in Pakistan, and from three locations of planted trees. In New York and North Carolina plantations, Himalayan white pine was attacked by white pine weevil (Pissodes strobi Peck).
