Root-zone temperature and water availability affect early root growth of planted longleaf pineThis article is part of a larger document. View the larger document here.
Longleaf pine seedlings from three seed sources were exposed to three root-zone temperatures and three levels of water availability for 28 days. Root growth declined as temperature and water availability decreased. Root growth differed by seed source. Results suggest that subtle changes in the regeneration environment may influence early root growth of longleaf pine and that root proliferation may vary by seed source.
