Abstract

Salinity is an increasing environmental problem that directly affects crop production. Foliar application of H2O2 stimulates the abiotic stress tolerance of plants is an important process. As an effective signaling molecule, H2O2 can reduce the deleterious effects of salt stress in plants. Application of exogenous H2O2 and H2O2 synthase inhibitor (DPI) to the eggplant genotypes Mardin (salt-tolerant) and Artvin (salt-sensitive) showed differential tolerance to salinity. We investigated the possible involvement of MDA content and activities of Catalase and Superoxide dismutase in these eggplant genotypes by foliar applications to seedling of H2O2 and DPI 48 hours before exposure to moderate salinity. H2O2 and MDA content increased upon salt stress and decreased upon H2O2 application. Antioxidant enzyme analysis showed that foliar spraying of H2O2 augmented antioxidant enzyme activities. This study shows that the salt-tolerant Mardin genotype is more affected by exogenously applied H2O2 and DPI than the salt-sensitive Artvin genotype.

Özet

Tuzluluk, bitkisel üretimi doğrudan etkileyen bir çevre sorunudur. H2O2’nin yapraktan uygulanması, bitkilerin abiyotik stres toleransını uyaran önemli bir süreçtir. Etkili bir sinyal molekülü olarak H2O2, bitkilerde tuz stresinin zararlı etkilerini azaltabilir. Bu çalışmada, Mardin (tuza dayanıklı) ve Artvin (tuza duyarlı) patlıcan genotiplerine dıştan uygulanan H2O2 ve H2O2 sentaz inhibitörü (DPI) uygulamasının olası etkileri araştırılmıştır. Patlıcan fidelerinin yapraklarına 48 saat boyunca H2O2 ve DPI uygulamalarının orta derecede tuzluluğa maruz kalan bu patlıcan genotiplerinde MDA içeriği ve Katalaz ve Süperoksit dismutaz aktivitelerinin olası katılımı araştırılmıştır. İçsel H2O2 ve MDA miktarları tuz stresi ile artış gösterirken, H2O2 uygulaması ile azalma göstermiştir. Yapraktan püskürtme yoluyla uygulanan H2O2 'nin antioksidan enzim aktivitelerini arttırdığı görülmüştür. Bu çalışma, tuza dayanıklı Mardin genotipinin, tuza duyarlı Artvin genotipine göre dıştan uygulanan H2O2 ve DPI' dan daha fazla etkilendiğini göstermektedir.
