Abstract

With climate change, global warming has increased adverse effects on living things in our country. In these adverse effects, water scarcity is the most crucial problem due to the increase in temperature and decrease in precipitation. Forests are the most affected ecosystem among others by water scarcity in our country. This study tried to determine the 5-year-old seeds and 1-year-old seedlings (produced from the same seeds) of some Turkish red pine provenance’ responses to different water stress levels. First, how the water stress levels (0, -0.2, -0.4, -0.6, -0.8 MPa) affect seed germination of these provenances was determined. Secondly, gas exchange parameters [net photosynthesis (Anet), stomatal conductance (gs), transpiration (E), and intrinsic water use efficiency (iWUE)] under different water stress were determined in the seedlings obtained from these species' seeds. As a result of the germination test, Denizli-Çameli (DC) provenance had the highest rate (48%), while Maraş-Suçatı had the lowest rate (29%) under control treatment. The highest germination rate was obtained in Burdur/Bucak provenance (5%) under -0.2 MPa osmotic potential. For gas exchange parameters, Antalya/Gündoğmuş provenance had the highest Anet, gs values while DC provenance had the lowest Anet, gs, and E values when provenance is considered as a single factor. Besides, increasing in irrigation increased Anet, gs, and E while decreased the iWUE. The lowest seedling E under water stress can be explained because this species responds to the water shortage by closing its stomata. Among the Turkish red pine origins, DC provenance showed higher drought tolerance than others.

Su Stresi Altındaki Bazı Kızılçam Kaynaklarının Tohum Çimlenme Oranı ve Fidelerin Gaz Değişim Performanslarının İncelenmesi

Abstract

İklim değişikliğiyle beraber küresel ısınmanın ülkemizdeki canlılar üzerindeki olumsuz etkileri artmıştır. Bu olumsuz etkilerden su kıtlığı, sıcaklık artışı ve yağışların azalmasıyla birlikte en önemli sorun olarak ortaya çıkmıştır. Ülkemizde su kıtlığından en çok etkilenen ormanlar ekosistemleridir. Bu çalışmada, bazı Kızılçam orijinlerinin 5 yaşındaki tohumları ve 1 yaşındaki fidelerinin (aynı tohumlardan üretilmiş) farklı su stresi seviyelerine tepkilerinin belirlenmesine çalışılmıştır. İlk olarak, su stresi seviyelerinin (0, -0.2, -0.4, -0.6, -0.8 MPa) bu tohum kaynaklarının çimlenmesini nasıl etkilediği belirlendi. Daha sonra, bu türlerin tohumlarından elde edilen fidelerin su stresi altında gaz değişim parametreleri [net fotosentez (Anet), stoma iletkenliği (gs), terleme (E), ve içsel su kullanma verimliliği (iWUE)] belirlenmiştir. Kontrol işleminde altındaki çimlenme testi sonucunda, en yüksek çimlenme oranı Denizli/Çameli (DC) orijininde (%48) belirlenirken, Maraş/Suçatı orijini en düşük orana (%29) sahiptir. -0.2 MPa ozmotik su gerilimi altında en yüksek çimlenme oranı Burdur/Bucak orijininde tespit edilmiştir. Orijin tek değişken olarak ele alınıp fidelerin gaz değişim parametreleri incelendiğinde ise en yüksek Anet ve gs Antalya/Gündoğmuş orijininde belirlenirken en düşük Anet, gs ve E ise DC orijininde tespit edilmiştir. Ayrıca sulamanın artması Anet, gs ve E’yi arttırırken iWUE’yi düşürmüştür. Türlerin en düşük E değerine sahip olması onların su stresine karşı somatalarını kapatarak tepki vermesiyle açıklanabilir. Kızılcam orijinleri arasında DC orijini diğerlerinden kuraklığa toleransı daha yüksektir.
