The influence of the ultrasound treatment on some physiological and biochemical parameters in Spinacia oleracea L. Seeds.

Keywords: Spinacia oleracea, ultrasounds, respiration intensity, catalase Abstract: The paper presents the results of a study regarding the respiration intensity and the activity of the catalase in the Spinacia oleracea L. seeds, subject to the action of ultrasounds with the frequency of 23 and 36 kHz, the electrical power of 7,4; 49,7; and 30 V.A., at the time intervals 20, 30, 40 and 60 seconds. The results obtained emphasize a stimulation effect of the germination of seeds and a slight intensification of the activity of catalase and the respiration intensity.
