Abstract

A 0.5% aqueous spray of potassium naphthenates was applied to the foliage of 14-day-old plants of bush bean, Phaseolus vulgaris L. cultivar Top Crop, and the plants were then grown under light intensities of 16.1, 10.76, and 5.38 klx at 26 °C for 7, 14, and 21 days. Photosynthesis, dark respiration, and phosphorylase activity were significantly greater (0.05 level) in treated plants at the end of all three growth periods under all light conditions. Significant stimulation of phosphoglycerate kinase developed more slowly under the lower light intensities. The stimulation of nitrate reductase and glutamic–pyruvic transaminase in treated plants reached a significant level between 7 and 14 days after treatment, and subsequently increased. The percentage increases of all the processes, over corresponding values in control plants, were greatest in plants grown at the highest light intensity.
