Amal H. Mahmoud( 2014). Hydrogen peroxide as a priming agent for alleviating soil salinity stress on wheat (Triticum aestivum) seedlings.J. Soil Sci. and Agric. Eng., Mansoura Univ., Vol. 5 (4): 455 - 470, 2014
Abstract: This work investigated the potential of two concentrations of H2O2 (0.10 and 0.20 mM) applied through irrigation water, as a priming factor, in reducing the detrimental effects of soil salinity stress on wheat (Triticum aestivum L.). Two wheat genotypes, Gemaiza 9 (G9) as a moderately salt sensitive and Sakha 93 (S93) as a salt tolerant, were grown in pots containing a saline clay soil (ECe of 7.35 dS/m) under greenhouse conditions for 45 days. The obtained results showed that H2O2 application at 0.10 and 0.20 mM stimulated the germination of G9 genotype by 10 and 20%, respectively. Both fresh and dry shoot weights of G9 had increased by 9.92 and 7.70 and 8.52 and 8.2% for 0.1 and 0.2 mM H2O2 treated plants, respectively, as compared to control treatment. In contrast, In S93 genotype, negative effects on germination and fresh and dry weight were recorded. The irrigation with 0.1mM H2O2- treated water markedly increased the tillers to about 100% and 22.2% in G9 and S93, respectively, while 0.2mM H2O2 treatment increased the tillers number to 28.6% more in G9 and decreased it 16.7% in S93. Addition of 0.2 mM H2O2 had a negative effect on chlorophyll A content in both cultivars. In G9, chlorophyll B and carotene content were promoted particularly by 0.2mM H2O2. Significant decreases in Na+ content in both cultivars were observed with H2O2 application while potassium was not markedly affected. The K+/Na+ ratio of G9 was lower than that in S93 in all treatments and tended to increase in both genotypes with H2O2 applications. It can be conducted that application of H2O2 as a physiological priming factor may play a significant role in growth improvement of moderately salt sensitive wheat genotypes such as G9 through promotion of Chlorophyll B synthesis and reduction of Na+ content.
