Stimulation Of

Plants of bush bean, Phaseolus vulgaris L., were sprayed with solutions of sodium and potassium naphthenates in the concentrations 50, 100, 500, 1000, 2500, and 5000 ppm. The treatments were applied when the plants were two, three, five, and seven weeks old, and also at various combinations of these times. A single application of 5000 ppm naphthenate to two-week-old plants, and multiple applications which included treatment of plants at this primary leaf stage of growth, resulted in the greatest stimulation to juvenile growth, measured as fresh and dry weights of stems and leaves, four weeks after treatment. This treatment also resulted in the greatest increase in green pod yield (20%), seven weeks after spraying, and in ripe seed production (8%). No advantage resulted from multiple treatments in these instances.

A solution containing 0.5 p.p.m. of atrazine, simazine, igran, or GS-14254 with 0.2% triton-B 1956 was applied to the foliage of 11-day-old seedlings of bush beans, Phaseolus vulgaris L. cultivar Tender-green, growing on vermiculite in a controlled environment. The activities of nitrate reductase, glutamic-pyruvic transaminase, α-amylase, starch phosphorylase, and adenosine triphosphatase were determined 5,10, and 20 days after treatment. In general, the activity of each of the five enzymes was stimulated by the treatment. The results suggest that protein increase following the application of.s-triazines to bean plants may stem in part from an enhanced rate of amino acid formation resulting from the induced increment in nitrate reductase and transaminase activity. The application of these chemicals also creates a metabolic condition favorable for greater use of carbohydrates needed for nitrate reduction and protein synthesis, and as a source of organic acid synthesis.

High Yield Potential

Eleven genotypes of french bean (Phaseolus vulgaris L.) were screened to select a suitable one which could provide optimum yield of fresh pod, dry seed and biochemical parameters. The maximum seed yield in french bean was found in case of genotype BB-9 (2.96 t/ha) and BARI bush bean -1 (2.95 t/ha), while that of minimum was found in BB-11(1.64 t/ha). However, maximum fresh pod yield (14.25 t/ha) was found for BARI bush bean -1, followed by BARI bush bean -2 (13.23t/ha). BARI bush bean -1 required the minimum time of 88.33 days while BB-3 the maximum of 110.00 days to attain 90% pods maturity. The highest number of diseased plants were observed in BB- 5 (30.33%) and the lowest were in BARI bush bean -1 (7.33%). No significant difference (P< 0.05) in maximum protein content among the studied genotypes was observed, for example BB-15 (21.60%) and BARI bush bean -1 (21.57%). Maximum crude fiber (5.53%) was obtained from BARI bush bean -1, followed by BB-6 (5.50%), BB-20 (5.50%) and BB-5 (5.47%), which all were statistically similar. Among all the genotypes, BARI bush bean -1 showed highest yield and superior quality of french bean. DOI: http://dx.doi.org/10.3329/bjsir.v49i4.22625 Bangladesh J. Sci. Ind.

Stimulation Of

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.
