Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2009, Vol 55, Issue 2
Abstract
The paper presents the results of a study referring to the behavior of the Cucumis sativus L. species to the ultrasound treatment during the germination process and in the first stages of seedlings growth. The seeds were subject to the ultrasound action with the frequency of 23 and 36 kHz, the electrical power of 7.4; 49.7; and 30 V.A., at time intervals of 20, 40 and 60 seconds. Two physiological indicators were taken in the study : the respiration intensity and the catalase activity. The results obtained emphasize specific value variations of the indicators analyzed according to ultrasounding conditions (frequency, electrical ultrasound power, exposal time) used in achieving the experiments. The observations carried out emphasize the fact that the ultrasound treatment stimulates the seeds germination.
