Notes: Development of Pinus Seedlings Grown from Seed Subjected to Drying and Wetting Cycles
Abstract:Seed of jack and Scots pine were subjected to up to five cycles of drying and rewetting. Seed moisture content, germination, and posttreatment seedling development were affected. Seedling development was evaluated on the basis of measurement of shoot and root length and dry weights. Scots pine germination and seedling development was more adversely affected by treatment than jack pine. Drying and rewetting of jack pine seed resulted in seedlings with shorter roots and shoots and lower root and shoot dry weights than untreated controls. Scots pine controls were heavier than treatment seedlings. Forest Sci. 24:537-541.
