Abstract
1. The telemorphic responses from 2,4-D noted in these experiments are in accord with those observed by other investigators. 2. In general, the application of 2,4-D resulted in retardation of carbohydrate and total dry-matter accumulation in the aerial portions of the plants. Decreases in carbohydrate deposition were grossly proportionate to decreases in dry-matter accumulation. 3. Translocation of 2,4-D, 2,4-D complexes, or unknowns in the bean plant appears to be closely associated with translocation of carbohydrates or their derivatives; conversely, these translocations or accumulations are profoundly influenced by applications of 2,4-D. 4. The dry matter accumulated in the various organs of the plant is largely accounted for by correspondingly lesser amounts of carbohydrates available. 5. Telemorphic and chemical responses to 2,4-D were observed above and below the place of application and varied considerably, depending upon the location of the area treated. 6. In general, the responses obtained in older, more mature plants were less pronounced than those obtained in young plants. 7. The data clearly indicate that environmental factors affect the magnitude of responses resulting from 2,4-D application. These responses may be attributable, at least in part, to the amounts of carbohydrates synthesized or capable of being translocated. 8. Data presented relative to total dry-matter accumulation in relation to fresh weight indicate that 2,4-D may have considerable influence on plant succulency.
