Abstract
In this study, Viburnum tinus L. (Evergreen Viburnum, Feathery Viburnum), an evergreen shrub frequently used in landscaping areas, was examined under uncontrolled glass greenhouse conditions for two years repeatedly to determine their responses to drought stress and subsequent recovery period. Plants were obtained 1 year before the start of the treatment in 1 year old and 2-3 liter pots. In the following year, drought treatment was applied until the first wilt was seen in the plants and irrigation was continued at field capacity in the control group. Recovery studies were terminated after the drought treatment was completed by irrigating the plants to field capacity and keeping them at field capacity for 15 days. Among the morphological parameters, shoot length decreased significantly in the first year of drought treatment. As a result of the recovery treatment, shoot length started to recover and 25% shorter shoot length was measured compared to the control group. This difference was not significant in other treatments. Photosynthesis, one of the physiological parameters, decreased in the two-year treatment compared to the control, but recovered rapidly in the second year as a result of the recovery after the drought treatment. Stomatal conductance showed similar results with photosynthesis in drought treatment. Leaf relative water content decreased compared to the control in both years, and the plant recovered to the same level as the control after the recovery treatment.

Abstract
Bu çalışmada, peyzaj düzenlemesi yapılan alanlarda sıkça kullanılan her dem yeşil çalılardan Viburnum tinus L. (Yaprak Dökmeyen Kartopu, Tüylü Kartopu), kontrolsüz cam sera koşullarında iki yıl tekrarlamalı olarak kuraklık stresi ve sonrasındaki iyileşme dönemindeki tepkilerinin belirlenmesi amacıyla incelenmiştir. Uygulamanın başlayacağı yılın 1 yıl öncesinden bitkiler, 1 yaşlı ve 2-3 litrelik saksılarda temin edilmiştir. Ertesi yıl kuraklık uygulaması bitkilerde ilk solgunluk görülünceye kadar suyun tamamen kesilmesi kontrol grubunda ise tarla kapasitesinde olacak şekilde sulamaya devam edilmiştir. İyileşme çalışmaları kuraklık uygulaması tamamlanan bitkilerin tarla kapasitesine kadar sulama yapılarak ve 15 gün tarla kapasitesinde tutularak gözlemlenmesinden sonra sonlandırılmıştır. Morfolojik parametrelerden sürgün uzunluğu kuraklık uygulamasının 1. yılında önemli derecede azalmıştır. İyileşme uygulaması sonucunda, sürgün uzunluğu düzelmeye başlamış olup, kontrol grubuna oranla %25 daha kısa sürgün uzunluğu ölçülmüştür. Diğer uygulamalarda bu fark belirgin değildir. Fizyolojik parametrelerden fotosentezin, iki yıl uygulamasında kontrole oranla azaldığı, 2. yıl bitkinin kuraklık uygulaması sonrasında yapılan iyileşme sonucunda oranının hızlıca düzeldiği görülmüştür. Stoma iletkenliği kuraklık uygulamasında fotosentez ile benzer sonuçları vermiştir. Yaprak nispi su içeriği her iki yılda da kontrole göre düşmüş, iyileşme uygulaması sonrasında bitki kontrol ile aynı seviyeler ulaştırmıştır. Membran geçirgenliği kuraklık ile artmamıştır ve membran hasarı görülmemiştir.
