Effects of altitude on transpiration, leaf vapor pressure deficit and leaf water potential in oriental beech

Öz

This study was designed to determine the effect of altitude on transpiration, leaf vapor pressure deficit and leaf water potential in oriental beech (Fagus orientalis Lipsky). The study area was located in Ortaköy, Artvin, and the experimental area had the same soil structure and aspect. The study showed that transpiration and leaf vapor pressure deficit increased but leaf water potential decreased by altitudinal gradient

Anahtar Kelimeler

• Fagus orientalis, transpiration, leaf vapor pressure deficit, leaf water potential

Doğu kayınında (Fagus orientalis Lipsky) yükseltiye bağlı olarak transpirasyon, yaprak buhar basınç açıklığı ve yaprak su potansiyeli değişimi

Öz

Bu çalışmada, Doğu kayınında transpirasyon (E), yaprak buhar basınç açıklığı (Vpdl) ve yaprak su potansiyeli (ΨL) fizyolojik parametrelerinin yükseltiye bağlı olarak değişimlerinin araştırılması amaçlamıştır. Artvin-Ortaköy’de doğal olarak yayılış gösteren doğu kayının bulunduğu meşcerede aynı bakı ve aynı toprak yapısı belirlenerek ölçümlerin farkının sadece yükseltiden kaynaklanabilecek değişiklikler olmasına özen gösterilerek fizyolojik değişiklikler belirlenmeye çalışılmıştır. Çalışma sonucunda, yükseltiye bağlı olarak transpirasyon ve yaprak buhar basınç açıklığının arttığı, buna karşın yaprak su potansiyeli değerinin ise önemli oranda azaldığı belirlenmiştir.
