Özet:

 The deleterious effects of abiotic stress factors, which have emerged in the context of global climate change, have a detrimental impact on agricultural production. Irregularity in seasonal rainfall and high temperatures make it difficult to meet the water needs of the plant. In addition, intensive fertilization, monoculture and use of poor-quality water in irrigation in vegetable fields cause salinity problems. It has been observed that both stress factors cause yield and quality losses in vegetable farming. For this purpose, in the present study, five different salt NaCl-S levels control S1 mains water500 µmhos, S2 2000 µmhos, S3 4000 µmhos, S4 6000 µmhos and S5 8000 µmhos and three different irrigation water levels full irrigation-I100, 75 irrigation-I75 and 50 irrigation-I50 were applied to melon seedlings in the study and their effects on photosynthetic activity and biochemical changes were tried to be determined. The study revealed that elevated levels of both stress factors resulted in a reduction in the growth of melon seedlings. Conversely, the findings indicated that superoxide dismutase SOD enzyme activity served as a significant indicator under both stress factor conditions. Furthermore, an increase in SOD activity was observed as stress levels escalated. In addition, it was seen that saline waters higher than 4000 µmhos would have a toxic effect on melon seedlings. It is important for the sustainability of melon farming that 25 water restriction can be applied in regions where irrigation water is limited.

 Küresel iklim değişikliği bağlamında ortaya çıkan abiyotik stres faktörlerinin zararlı etkileri tarımsal üretim üzerinde olumsuz etki yaratmaktadır. Mevsimsel yağışlardaki düzensizlik ve yüksek sıcaklıklar bitkinin su ihtiyacının karşılanmasını zorlaştırmaktadır. Ayrıca sebze tarlalarında yoğun gübreleme, monokültür ve sulamada kalitesiz su kullanımı tuzluluk sorunlarına yol açmaktadır. Her iki stres faktörünün de sebze yetiştiriciliğinde verim ve kalite kayıplarına yol açtığı görülmüştür. Bu amaçla, bu çalışmada kavun fidelerine beş farklı tuz NaCl-S seviyesi kontrol S1 şebeke suyu500 µmhos, S2 2000 µmhos, S3 4000 µmhos, S4 6000 µmhos ve S5 8000 µmhos ve üç farklı sulama suyu seviyesi tam sulama-I100, 75 sulama-I75 ve 50 sulama-I50 uygulanarak fotosentetik aktivite ve biyokimyasal değişimler üzerine etkileri belirlenmeye çalışılmıştır. Çalışma, her iki stres faktörünün de artan seviyelerinin kavun fidelerinin büyümesinde bir azalmaya neden olduğunu ortaya koymuştur. Diğer yandan, bulgular süperoksit dismutaz SOD enzim aktivitesinin her iki stres faktörü koşulunda da önemli bir gösterge olarak görev yaptığını göstermiştir. Ayrıca, stres seviyeleri arttıkça SOD aktivitesinde bir artış gözlenmiştir. Ayrıca 4000 µmhostan yüksek tuzlu suların kavun fideleri üzerinde toksik etki yaratacağı görülmüştür. Sulama suyunun kısıtlı olduğu bölgelerde 25 su kısıtlaması uygulanabilmesi kavun yetiştiriciliğinin sürdürülebilirliği açısından önemlidir.
