Book excerpt: The growth, regeneration, and quality of white pine between the 1970's and 1980's were analyzed for the six-state New England region. Growth was comparable among all states except for Rhode Island where the growth (1.71%) was low in comparison with other states and with the growth of red maple (4.29%) within the state. For all states, the proportion of acreage in white pine seedling/sapling stands was too small (8%) to maintain the current volume and acreage of the species. However, stems in the 2- to 10-inch diameter class were adequately J-shaped over all states to sustain the species. Because many of these small stems must be in small openings or under partial canopies, efforts to regenerate and release white pine seem warranted. The percentage of volume in grades 1 and 2 more than doubled between the 1970's and 1980's in all states except Massachusetts and Connecticut where the percentage remained about constant.

Book excerpt: S2The purpose of our study was to examine some of the factors that influence seedling emergence and seedling survival of direct-seeded white pine (Pinus strobus L.). Our major concern was the response of white pine to a particular set of growing conditions on the seedling emergence pattern, on seedling survival, and on the causes of seedling mortality. S3.

Available in PDF, EPUB and Kindle. Book excerpt: Eastern white pine provenances from the extreme limits of its natural range are changing from above- and below-average stability to average stability for height growth with increasing age. The regression method is useful for evaluating the stability of provenance to planting sites. The same general conclusions are reached for the performance of provenances at different planting sites from the regression method as from the relative difference method.

Download or read book Effect of Seed Mass on Early Seedling Growth of Five Eastern White Pine Pinus Strobus L Families Under Contrasting Light Environments written by and published by . This book was released on 2004 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide variation in initial spatial patterns of natural regeneration of eastern white pine between managed & undisturbed white pine forests of the Great Lakes region has been attributed to differences in understory light levels and the frequency of substrates suitable for germination & seedling establishment. This paper describes a greenhouse study of the interaction of seed mass & light on early white pine which was undertaken to explore the potential influence of seed mass on these observed patterns. Seedlings of five families differing in mean seed mass were grown for 8 & 14 weeks under moderate & low light conditions representing managed & undisturbed pine stands respectively. The results suggest whether differential recruitment of white pine in managed & undisturbed stands is related to variation in seed mass.
