Photoacoustic (PA) technique was used to study ethylene and CO2respiration emission rates from germinating bean (Phaseolus vulgaris L) seeds. The concentration of ethylene was measured at 10P(12) and 10P(14) lines of the CO2laser with the PA cell in the intracavity configuration. On the other hand, the respiration rate of CO2was deduced (precision 1 ppm) from the concentration data measured by the commercial PA analyser operating in the infrared range. The objective of this study was to obtain better understanding of insulin signalling in the germinating seeds. The experiments were performed with seeds imbibed either in water or in aqueous solution of insulin (0,9 μg.mL-1H2O). |
