Abstract

Salicylic acid (S A) is recognized as an endogenous regulator of plant metabolism, mainly involved in biotic and abiotic stress. The objective of this study was to investigate the effects of different concentration (50, 100 and 200 ppm) of S A on greenhouse and field grown Phaseolus vulgaris L. seedlings growth, some physiological and biochemical parameters. Plant growth and development showed different results depending on growth conditions and treated SA concentration. Photosynthetic pigments (chlorophyll a, b and carotenoids) contents were all increased in greenhouse grown plants at 100 ppm SA treatment around 30%. In field grown plants, 50 ppm SA treatment caused an increase in chlorophyll a, b and carotenoids about 10%. In greenhouse and field grown plants, while 50 and 100 ppm SA treatment increased total nitrogen contents of plants, 200 ppm SA treatment caused a decrease compared to untreated control plants in both growth conditions. The results indicate that SA has a positive effects, on plant growth and nitrogen metabolism showing dose depended manner.

Özet

Salisilik asit (SA), temel olarak abiyotik ve biyotik stres tepkilerinde yer alan bitki metabolizmasının endojen bir düzenleyicisidir. Farklı konsantrasyonlardaki (50, 100 ve 200 ppm) SA'in sera ve tarla koşullarında yetiştirilen Rhhseolus vulgaris L. fidelerinin bitki büyümesi ile bazı fizyolojik ve biyokimyasal Özellikleri üzerindeki etkisini araştırmak bu çalışmanın konusunu oluşturmaktadır. Fasulyede büyüme ve gelişme, yetişme koşullan ve uygulanan SA konsantrasyonuna bağlı olarak farklı nitelikler göstermektedir. Fotosentetik pigment (klorofil a, b ve karotenoidler) içerikleri açısından, serada yetiştirilen bitkilerde etkili uygulama 100 ppm SA olarak belirlenmiş ve bu uygulama her üç pigment miktarında yaklaşık %30 artışa neden olmuştur. Tarlada yetiştirilen bitkilerde ise 50 ppm SA uygulaması ile klorofil a, b ve karotenoidlerin miktarının yaklaşık %10 oranında arttığı belirlenmiştir. Sera ve tarlada yetiştirilen her iki grup bitkiye 50 ve 100 ppm S A uygulaması toplam azot içeriğini artırırken, 200 ppm S A uygulaması iki grup bitkide de kontrole göre bu değerlerde azalmaya neden olmaktadır. Sonuçlar, SA'in bu bitkinin büyüme ve azot metabolizması üzerinde uygulanan doza bağlı olarak olumlu etkisi olduğunu göstermektedir.
