Abstract
Zea mays and Helianthus annuus are considered most important oil crops in the world due to the favorable fatty acid composition of the oil for human consumption, so efforts must be done to increase the yield and the desirable constituents in the two plants. In the present study the seeds of the plants were primed by soaking in two different concentrations of ascorbic acid solution or yeast extract (1% and 2%) for 12 hour. The plants were grown under greenhouse conditions and irrigated with tap water. It was found that, all these treatments significantly increased germination percentage, shoot growth parameters, photosynthetic pigments, soluble proteins and phytohormones in both Zea mays and Helianthus annus. It was observed that, 1% yeast extract was the most promotive treatment for Zea while for Helianthus annus it was 2% ascorbic acid. The protein profile showed the induction of several new protein bands with all treatments. These new bands revealed a changed pattern of gene expression after yeast and ascorbic acid treatments. Finally, the applied treatments decreased the percentage of saturated fatty acids and increased the unsaturated fatty acids in both the tested plants
