Nutrient experiments, in which various concentrations of nitrogen, potassium, and phosphorus were supplied, indicated that the pale-green color of plant tissue induced by applications of gibberellic acid (GA) could not be counteracted by increasing the available concentration of any of these elements singly. Characteristic chlorosis of the lower leaves was exhibited by those untreated and GA-treated plants receiving the low level of nitrogen. Typical potassium deficiency symptoms developed only in the GA-treated plants. These symptoms were slower to appear and less severe as the concentration of potassium applied to GAtreated plants increased. The amount of phosphorus in plant tissue was slightly less in GA-treated plants as compared to untreated ones receiving the same concentration of the element. The uniform pale-green color of GA-treated plants was not identical with characteristic deficiency symptoms of any of the three elements varied in this investigation.
