Effects of Root Dips of Benomyl and Captan on Seedling Response and Mycorrhizal Development of Outplanted Longleaf, Sand, and Loblolly Pines. Progress Report

摘要

The longleaf pine study evaluating the effects of root-stripping treatments, ectomycorrhizal condition, and seedling density in the nursery bed was terminated after collection of survival and growth data at the end of the second growing season. The striking effect of root stripping (simulating removal of short roots and ectomycorrhizae by lifting machines) that was reported after the first growing season was evident after the second growing season in terms of survival and root-collar diameters.
