Abstract

Salinity is an important abiotic stress which reduces the productivity and quality of agricultural areas by also negatively affecting plant growth and development. This study was conducted to determine changes on some morphological, physiological and biochemical parameters caused by different salt concentrations as well as to determine the effect of exogenous salicylic acid (SA) application on these changes for basil plant (Ocimum basilicum L.) which has an economical value due to its nice odor and essential oil content. Plant heigth, number of tree branches, fresh and dry herbal weights, pigment contents of leaves and antioxidant enzyme activities decreased for plants on which only NaCl (25 and 50 mM) application was made but foliar SA application was not; while malondialdehyde (MDA) content and essential oil ratios increased on leaves of the plants. While plant heigth, number of tree branches, fresh and dry herbal weights, pigment contents of leaves did not generally change for plants which were subjected to NaCl stress after foliar SA application; MDA content, essential oil ratios and antioxidant enzyme activities increased. This study has shown that exogenous SA application decreased in general negative effects caused by salt stress.

Özet

Tuzluluk bitki büyüme ve gelişmesini olumsuz etkileyerek tarımsal alanlarda verim ve kaliteyi düşüren önemli bir abiyotik strestir. Bu çalışma, güzel kokusu ve uçucu yağ içeriği ile ekonomik bir değere sahip olan reyhan (Ocimum basilicum L.) bitkisinde farklı tuz konsantrasyonlarının bazı morfolojik, fizyolojik ve biyokimyasal parametreler üzerinde meydana getirdiği değişimleri belirlemek ve bu değişimler üzerine dışsal salisilik asit (SA) uygulamasının etkilerini saptamak amacı ile yapılmıştır. Yapraklara SA uygulaması yapılmadan sadece NaCl (25 ve 50 mM) uygulanan bitkilerde bitki boyu, dal sayısı, taze ve kuru herba ağırlıkları, yaprakların pigment içerikleri ve antioksidan enzim aktiviteleri azalmış, buna karşın yapraklardaki malondialdehit (MDA) içeriği ve uçucu yağ oranları artmıştır. Yapraklara 0.5 mM SA uygulaması yapıldıktan sonra NaCl stresine maruz kalan bitkilerde ise bitki boyu, dal sayısı, taze ve kuru herba ağırlıkları ile pigment içerikleri genel olarak değişmezken, MDA içeriği, uçucu yağ oranları ve antioksidan enzim aktiviteleri artmıştır. Bu çalışma, dışsal SA uygulamasının genel olarak tuz stresinin sebep olduğu olumsuz etkileri azalttığını göstermiştir.
