Abstract
Amaç: Bu çalışmada, beş farklı üzüm çeşidinin farklı budama şekilleri ve iklim şartlarınagösterdiği fizyolojik tepkileri incelenmiştir.Materyal ve Metot: Deneme Tekirdağ Bağcılık Araştırma Enstitüsü’nde Milli KoleksiyonBağından seçilerek kurulan şaraplık çeşit araştırma parsellerinde 2018 yılındayürütülmüştür. Karamenüş, Yayla, Tilkiboğan, Aksıdağan ve Beyaz üzüm çeşitleri kordonve guyot budama şekilleriyle terbiye edilerek yetiştirilmiştir. Arazi şartlarında fotosentez(A), transpirasyon (E), stoma iletkenliği (gs) ölçümleri yapılmış, çeşitlerin anlık ve gerçeksu kullanım randımanları (WUE) hesaplanarak, çevresel etmenlerle etkileşimleri tespitedilmiştir.Bulgular: İzlenen fizyolojik parametrelerin gerçek su kullanım randımanı dışındafarklı budama şekillerinden etkilenmediği, bu değişkenleri kontrol eden asıl unsurunmezoklimatik iklim şartları olduğu belirlenmiştir.Sonuç: Karamenüş ve Beyaz üzüm çeşitleri ölçüm günlerindeki farklı iklimsel etkilereen etkin biçimde uyum gösteren çeşitler olarak öne çıkmıştır. Aksıdağan çeşidi yüksekoransal nem, Tilkiboğan çeşidi yükselen ışık şiddeti, Yayla çeşidi yüksek nem, düşük ışıkşiddeti ve yükselen rüzgar hızında su kullanım etkinliklerini artırmışlardır.
Objective: In this study, the effects of different pruning types and climatic conditions on the physiological responses of five different grape varieties were investigated. Material and Methods: The trial was conducted in 2018 in the research parcels of wine varieties established by selecting from the National Collection Vineyard in Tekirdağ Viticulture Research Institute. Karamenüş, Yayla, Tilkiboğan, Aksıdağan and Beyaz üzüm varieties were cultivated with Cordon Royat and Guyot pruning forms. Photosynthesis (A), transpiration (E), stoma conductivity (gs ) measurements were made under field conditions, instantaneous and intrinsic water usage efficiency (WUE) of the varieties were calculated and interactions with environmental factors were discussed. Results: It was determined that the monitored physiological parameters were not affected by different pruning forms. Only intrinsic water usage efficiency was affected by pruning. The primary factor controlling these parametres were climatic conditions. Conclusion: Karamenüş and Beyaz üzüm varieties were the most adaptable varieties to different climatic influences on the measurement days. Water use efficiencies were increased under high proportional humidity for Aksıdağan cultivar and high light intensity for Tilkiboğan cultivar. Also Yayla grape variety increased instrinsic water usage efficiency with high humidity, low light intensity and rising wind speed conditions.
