Uniformity of plant growth, which is important for efficient mechanization, is influenced by uniformity of seed germination. Since germinability characteristics of tobacco (Nicoticznu tabacum L.) seed produced in a phytotron are affected by the environment during develop ment of the mother plant, a field experiment was conducted to determine if measurable changes in germinability of seed result from alterations in cultural practices during mother-plant growth. Cultural variables were N-applied at 50, 72, and 94 kg ha−1 and normal or no leaf harvest. The increases in N applied to the mother plant reduced the time and enhanced the uniformity of seed germination. Leaf harvest had no effect on germinability characteristics. These effects were not significantly correlated with seed size.
