The Effect of Drought Stress on Antioxidative Enzyme and Nutrient Exchange in Some Tomato Genotypes

Öz:
Along with global warming, serious reductions occurred in water resources. The drought stress resulting from global warming has greatly affected production. As well as reducing yield and quality in production, drought also reduces farmer's income. One of the measures to be taken in order to minimize the damage caused by the effect of drought stress is to determine the tolerance of the genotypes to drought. Accordingly, three hybrids varieties, three standards varieties and three landraces of tomatoes were used in the present study. Tomato seeds were sown in a 2 liters-pot that contains 1:1 mixture of peat + perlite. After the true leaves emerged, the seedlings were irrigated with the Hoagland nutrient solution. While irrigation was carried on the control plants until the end of the application, irrigation was completely terminated during the seedling period in the plants that are exposed to drought. 12 days after the irrigation cut in tomato genotypes, the changes in the level of catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), potassium (K), calcium (Ca) and magnesium were examined. It was observed that there were significant differences in these parameters examined for the determination of tomato genotypes that are tolerant and sensitive to drought stress.

Kuraklık Stresinin Bazı Domates GenotiplerindeAntioksidatif Enzim ve Besin Elementi Değişimleri Üzerine Etkileri

Öz:
Küresel ısınmayla birlikte su kaynaklarında ciddi azalmalar meydana gelmiştir. Küresel ısınmanın sonucu ortaya çıkan kuraklık stresi üretimi büyük oranda etkilemiştir. Kuraklık stresi verim ve kaliteyi azaltmasının yanı sıra üreticilere de maddi sıkıntılar yaşatmaktadır. Kuraklık stresinin etkisine bağlı olarak oluşan hasarların en aza indirgenmesi amacıyla alınacak önlemlerden bir tanesi de kuraklığa tolerant çeşitlerin belirlenmesidir. Bu nedenle mevcut çalışmada kuraklığa tolerans gösteren domates genotiplerinin belirlenmesi amaçlanmıştır. Çalışmada üç adet hibrit, üç adet standart ve üç adet mahalli domates çeşidi kullanılmıştır. Domates tohumları 1:1 oranında torf + perlit karışımı içeren 2 litrelik saksılara ekilmiştir. Gerçek yapraklar oluştuktan sonra fideler, Hoagland besin çözeltisiyle sulama yapılmıştır. Sulama, kontrol bitkilerinde çalışma bitirilinceye kadar devam ederken, kuraklık uygulanan bitkilerde ise fide döneminde sulama tamamen kesilmiştir. Sulama kesildikten 12 gün sonra domates genotiplerindekatalaz (CAT), süperoksitdismutaz (SOD), askorbatperoksidaz (APX), potasyum (K), kalsiyum (Ca) ve magnezyum (Mg) içeriklerindeki değişimler incelenmiştir. Kuraklık stresine tolerant ve duyarlı domates genotiplerinin belirlenmesinde incelenen bu parametrelerde bariz farklar oluştuğu gözlemlenmiştir.
