Two field experiments were carried out in the experimental farm of Faculty of Desert and Environmental Agriculture, Fuka, Matrouh Branch, Alexandria University, Egypt, during two successive seasons 2012/2013 and 2013/2014 to study the effect of seed priming with Ascorbic and Salicylic Acids and spraying with silicon on drought tolerance of two barley cultivars, Giza 126 and Giza 2000. Six treatment were used as follows: Seed priming with Ascorbic acid (AA) and irrigation till heading (T1), seed priming with Salicylic acid (SA) and irrigation till heading (T2), seed priming with distilled water and irrigation till heading (T3), spraying with silicon and irrigation till heading (T4), dry seeds cultivation and irrigation till heading (T5) and dry seeds cultivation and all season irrigation (T6). The results indicated that post anthesis stress decreased grain yield by 17.1 % and 100-grain weight by 11.96 %, as an average of the two seasons. Hydropriming and osmopriming with salicylic acid, in addition to spraying with silicon, decreased the effect of drought and barley plants gave comparable grain yield to that of non-stress conditions. Barley cultivar Giza 126 was more tolerant to late drought compared to Giza 2000 cultivar with S values of 0.58 and 1.42, as an average of the two seasons, respectively.

    One of the effects of reducing water content on soil is reduction of growth and development of seedlings and variation of field development. Seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stresses. The objectives of this research were to evaluate the effects of osmo-priming on germination characteristics and changes of proline, protein and catalase activity of Ocimum basilicum seeds. Results showed that drought stress reduced the germination characteristics and drought stress in -8 bar was the critical stress.  Priming treatments were include KNO3, PEG and NaCl by 0, -4 and -8 bar concentrations. The seeds were primed with those materials for 8 and 16 hours. The highest germination characteristics were obtained from nitrate potassium in -8 bar for 16 hours priming. Therefore the best seed treatment under drought stress during germination was obtained from the osmo-primed with -8 bar nitrate potassium for 16 hours. The drought stress increased proline and catalase activity but reduced total protein. Priming treatment increases proline, total protein and catalase activity under drought and control conditions. It is concluded that priming results in improvement in germination components of Ocimum basilicum in drought stress conditions and increases the resistance to drought stress with improvement of proline, protein and catalase activity in germination phase.
