Özet:

 Floods caused by climate change are a significant abiotic stress factor that has a profound impact on plant growth and development, substantially affecting crop yield. One of the most important strategies today to mitigate the adverse effects of flood stress is the cultivation of tolerant species or varieties. In this study, the effects of artificially induced ten-day flood stress on the agronomic, physiological, and biochemical changes of commercially grown Arıcan 97 and Balkız pumpkin varieties were investigated. The study was conducted using a randomized complete block design, with two irrigation treatments: full irrigation and artificially induced flood stress. Each treatment was organized with three replicates, and each replicate included three pots. At the end of the stress period, all treatments were harvested on the same day, and agronomic, physiological, and biochemical measurements were conducted to determine the effects of flood stress on the pumpkin varieties. The results indicated that flood stress caused significant losses in the agronomic characteristics of the pumpkin varieties at the seedling stage. The results obtained from different harvest periods under flood stress in pumpkins were subjected to Principal Component Analysis PCA. The first five components explained 87.060 of the variation in the study, showing that these components captured a high proportion of the variability. As a result, for pumpkin cultivation in the Sakarya region, it is crucial to avoid lowland areas where the natural flow of water is slow, and which are located near riverbeds, as they pose a high risk of flooding.

 İklim değişikliği kaynaklı sel su baskınları, bitki büyümesi ve gelişimi üzerinde önemli bir etkiye sahip olup verimi büyük ölçüde etkileyen abiyotik stres faktörlerindendir. Sel baskını stresinin olumsuz etkisinden korunmak için tolerant tür veya çeşitlerin kullanılması en önemli stratejilerden birisidir. Bu amaçla yapılan çalışmada, kestane kabağında oluşturulan on günlük sel baskını stresinin, Sakarya bölgesinde yoğun olarak yetiştiriciliği yapılan Arıcan 97 ve Balkız çeşitlerinin, agronomik, fizyolojik ve biyokimyasal değişimleri üzerine etkileri belirlenmeye çalışılmıştır. Tesadüf parselleri deneme deseni kullanılarak yürütülen çalışmada, tam sulama ve yapay sel baskını stres konularını içeren iki sulama uygulaması yapılmış; her uygulama, üç tekrarlı ve her tekrarda üç saksı olacak şekilde düzenlenmiştir. Çalışma sonucunda, sel baskını stresi kabak çeşitlerinin fide döneminde agromorfolojik özelliklerinde önemli kayıplara neden olmuştur. Kestane kabağında sel stresinde farklı hasat dönemlerinde elde edilen sonuçlar temel bileşenler analizine PCA tabi tutulmuştur. Bileşenler göz önüne alındığında ilk beş bileşen çalışmanın  87,060ını açıklamıştır. Dolayısıyla ilk beş bileşenin çalışmayı yüksek oranda açıkladığı görülmüştür. Sonuç olarak, özellikle Sakarya bölgesinde kabak yetiştiriciliği için sel baskını riski taşıyan ve suyun doğal akışının yavaş olduğu, akarsu ve nehir yataklarına yakın taban arazilerinin tercih edilmemesi büyük önem taşımaktadır. Bu tür arazilerde, verim ve kalite kayıplarını önlemek amacıyla tolerant çeşitlerin kullanılması önerilmektedir.
