Abstract:

 Germination and seedling growth periods have a very important function in plant life. Especially in cases where abiotic stress conditions occur, these periods are of vital importance for the sustainability of plant life. Taking this into account, this research was conducted to determine the most suitable temperature for germination and seedling growth parameters of cotton varieties. In this research conducted under controlled conditions, germination and seedling development parameters of two cotton varieties May-344 and Candia were tested at 8 different temperature levels 8, 12, 16, 20, 24, 28, 32 and 36C. It was determined that the germination percentage was 45.17-16.17, the germination time was 4.06-3.94 days and the emergence rate index was 1.89-0.58 in May-344 and Candia cotton varieties, respectively. Moreover; root length 37.89-16.43 mm, stem length 44.69-41.00 mm, root fresh weight 22.40-19.51 mg, stem fresh weight 90.37-131.80 mg and the rootstem ratio was 0.26-0.16 mgmg in May-344 and Candia cotton varieties, respectively. The results of the experiment revealed that most of the tested parameters were significantly affected by temperature. The highest germination rate, as the average of the two varieties and for both varieties separately, was obtained at 20 oC and no germination occurred at 8 oC. Except root to shoot ratio, other seedling growth parameters were maximum between 20-32 oC and decreased at higher temperatures.

 Bitki yaşamında çimlenme ve fide büyüme periyodu çok önemli bir fonksiyona sahiptir. Özellikle abiyotik stress koşullarının oluştuğu durumlarda bu periyotlar bitki yaşamının sürdürülebilirliği için hayatı derecede öneme sahiptirler. Bu durum dikkate alınarak pamuk çeşitlerinin çimlenmesi ve fide büyüme parametreleri açısından en uygun sıcaklık derecesinin tespit edilmesi amacıyla bu araştırma yürütülmüştür. Kontrollü koşullar altında yürütülen bu araştırmada, iki pamuk çeşidinin May-344 ve Candia çimlenme ve fide gelişim parametreleri 8 farklı sıcaklık seviyelerinde 8, 12, 16, 20, 24, 28, 32 ve 36C test edilmiştir. Araştırma sonucu May-344 ve Candia pamuk çeşitlerinde sırasıyla çimlenme yüzdesinin 45,17-16,17, çimlenme süresinin 4,06-3,94 gün ve çıkış oranı indeksinin 1,89-0,58 olduğu belirlenmiştir. Ayrıca; May-344 ve Candia pamuk çeşitlerinde sırasıyla kök uzunluğu 37,89-16,43 mm, gövde uzunluğu 44,69-41,00 mm, kök taze ağırlığı 22,40-19,51 mg, gövde taze ağırlığı 90,37-131,80 mg ve kökgövde oranı 0,26-0,16 mgmg olarak bulunmuştur. İlave olarak test edilen parametrelerin çoğunun sıcaklıktan önemli ölçüde etkilendiğini belirlenmiştir. Her iki pamuk çeşidinin ortalaması ve her iki çeşit için ayrı ayrı en yüksek çimlenme oranı 20 oCde elde edilmiştir. 8 oCde ise çimlenme kaydedilmemiştir. Köksürgün oranı dışında diğer fide büyüme parametreleri 20-32 oC arasında maksimuma ulaşırken, daha yüksek sıcaklıklarda azalmıştır.
