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.

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.
