Changes in morphology and physiology of Convolvulus oleifolius var. Deserti in different habitats

Abstract

Morphological features, photosynthetic pigment contents, proline and total protein amounts of Convolvulus oleifolius Desr. var. deserti Pamp./Surmeli yayilgan in different vegetation zones of Apostol Island are studied. Samples were collected from littoral-epilittoral and interior vegetation zones of Apostol Island, Bodrum-Turkbuku-MuglaTurkey. There are obvious differences in terms of stem length, organ size, hair density and inflorescence. Photosynthetic pigments in littoral-epilittoral vegetation zone are less than in interior vegetation zone. Prolin amount is significantly higher, but total protein amount is significantly lower in littoral-epilittoral vegetation zone than in interior vegetation zone. It may be thought that the morphological and physiological features of the C. oleifolius var. deserti exhibited considerable differences which appeared be the product of adaptive mechanisms to different habitat. So, our study is important for improving and selecting crops tolerant of and/or adapted to different habitat

Farklı habitatlarda Convolvulus oleifolius var. Deserti’nin morfoloji ve fizyolojisinde değişimler

Abstract

Apostol adasının farklı vejetasyon zonlarında bulunan Convolvulus oleifolius Desr. var. deserti Pamp./Sürmeli yayılgan’ın morfolojik özellikleri, fotosentetik pigment içerikleri, prolin ve toplam protein miktarları çalışılmıştır. Örnekler Bodrum-Türkbükü-Muğla-Türkiye, Apostol adasının littoral-epilittoral ve interior vejetasyon zonlarından toplanmıştır. Gövde uzunluğu, organ büyüklüğü, tüy yoğunluğu ve çiçeklenme durumunda belirgin farklılıklar vardır. Fotosentetik pigmentler littoral-epilittoral vejetasyon zonda, interior vejetasyon zondakinden daha azdır. Littoralepilittoral vejetasyon zonda prolin miktarı interior vejetasyon zondakinden önemli derecede daha yüksekken, toplam protein miktarı önemli derecede daha düşüktür. C. oleifolius var. deserti’nin morfolojik ve fizyolojik özelliklerinin çeşitli habitatlara uyum mekanizması sonucu ortaya çıkan önemli farklılıkları sergilediği düşünülebilir. Bu nedenle, çalışmamız farklı habitatlara uyumlu ve/veya toleranslı bitkilerin seçilmesi ve değerlendirilmesi için önemlidir
