Abstract
Tomatoes reportedly have a positive response to seed priming. The present study evaluates the effects of ethanol priming on germination, seedling vigour and antioxidative responses of tomato seeds. Priming was achieved by exposing seeds of ‘Roma’ and ‘Nagina’ to 2, 4 and 6% aerated ethanol solutions for 24 h. Priming with low levels (2 and 4%) of ethanol improved seed germination, seedling vigour and enhanced antioxidative activity that results in better performance of tomato seeds. However, priming with 6% ethanol failed to improve seed germination and seedling development which relates to the decreased anti-oxidative activity in tomato seeds due to high ethanol level.
