Effect of ultrasonic treatment on seed germination and seedling emergence in seven vegetable species

This study was performed to determine the effect of ultrasound treatment on seed germination, seedling emergence and mean germination times in seeds watermelon, melon, leek, pepper, carrot, tomato aubergine. Seeds treated with 40 kHz over 30 minutes (US), hydroprimed (HP) dry controls (C) were tested. US-treated had 85% percentages compared 82 78% for HP C seeds, respectively. Corresponding values 83, 75 72%. US reduced times. The maximum advantages obtained from observed watermelon (13%), carrot (11%), pepper leek (10%), (7%) Advantages by greatest (20%), (22%) (13%) (14%), (12%), melon (10%) HP. both Results showed that more effective than germination. treatments have potential increase vegetable seeds.
