Bu çalışma, yaprak su potansiyelindeki değişikliklerin ve farklı yaprak alma işlemlerinin yaprak alanı özelliklerini nasıl etkilediğini değerlendirmeyi amaçlamıştır. Araştırma, Kalpak Şatosu'nun Tekirdağ, Şarköy bağlarında yetiştirilen 'Merlot'/41B kombinasyonlu asmalarda iki yıl süresince (2019-2020) yürütülmüştür. Yaprak su potansiyeli ölçümlerine dayalı olarak dört farklı su stresi seviyesi (S0, S1, S2 ve S3) uygulanmıştır. Ek olarak, Kontrol (C), Tam Pencere (FW), Sağ Pencere (RW) ve Sol Pencere (LW) olmak üzere dört farklı yaprak alma işlemi uygulanmıştır. Daha yüksek stres seviyelerinin, asma başına artan ana, koltuk ve toplam yaprak artış eğilimine neden olduğu belirlenmiştir. FW uygulaması, asma başına toplam ana yaprak alanı dışında tüm kriterlerde bir azalmaya yol açmıştır. FW, kontrollü koşullarda belirli yaprak parametrelerinde düşüşe neden olurken, toplam yaprak alanında stresin neden olduğu artış, asmalardaki plastidite mekanizmasına işaret etmekte ve farklı çevresel ve üretim dinamikleri altında daha fazla araştırma yapılmasını gerektirdiğini göstermektedir.

This study aimed to assess how variations in leaf water potential and different defoliation treatments influence leaf area characteristics. The research was carried out during two consecutive years (2019-2020) on 'Merlot'/41B combination grapevines cultivated in the Tekirdağ, Şarköy vineyards of Chateau Kalpak. Four distinct water stress levels (S0, S1, S2, and S3) were implemented based on measurements of leaf water potential. Additionally, defoliation treatments were applied, including Control (C), Full Window (FW), Right Window (RW), and Left Window (LW). Upon analyzing leaf characteristics, a clear trend emerged, wherein higher stress levels correlated with an increased area of primary, lateral, and total leaves per vine. Concerning leaf removal interventions, the application of FW led to a reduction in all criteria except for the total area of main leaves per vine. While FW causes a decrease in certain leaf parameters under controlled conditions, the stress-induced increase in total leaf area points to the mechanism of plasticity in grapevines and warrants further investigation under different environmental and production dynamics.
