The morphological and physiological responses to nitrogen (N) limitation in jack pine (Pinus banksiana Lamb.) seedlings were studied following the initiation of four different dynamic N treatments for six and 15 weeks. The N treatments produced needle N concentrations from 11 to 31 mg g-1dry weight, and seven-fold difference in dry weight at 15 weeks. Low-N jack pine seedlings: 1) had an higher root/shoot ratio; 2) extended their tap root more rapidly; 3) were better able to maintain turgor… CONTINUE READING
