The role of plant hormones, carbohydrates and indolebutyric acid in root and shoot development of two transplanted woody species

Field and laboratory experiments were conducted to examine the roles of endogenous and applied plant hormones in the control of root and shoot development of woody plants. An experiment was conducted to determine the effectiveness of IBA root sprays applied to seedling red oaks up to two weeks prior to planting. Bare root Quercus rubra seedlings were sprayed with 0, 3000, 6000 and 9000 ppm of IBA at 0, 3, 7 and 14 days prior to planting in containers or in the field. After the second year of field growth, plants treated with 9000 ppm of IBA on the planting date and 3 and 14 days prior to planting, produced 49.9, 122.2 and 110.4% increases in shoot growth over plants that received no IBA. Plants that received 6000 ppm of IBA showed the greatest amount of shoot growth after 3 years regardless of treatment time. The results indicate that root regeneration and shoot growth of red oak can be increased with IBA root sprays applied up to two weeks prior to planting.
