Taban ve kıraç koşullar gibi iki farklı çevrede yetiştirilen ekmeklik ve makarnalık buğday genotiplerinin stoma sayılarının incelendiği bu çalışma, 2002 yılında Çukurova Üniversitesi, Ziraat Fakültesi, Tarla Bitkileri Bölümü, Uygulama ve Araştırma Alanları ile Bölüm laboratuvarlarında; altı ekmeklik ve beş makarnalık buğday genotipi kullanılarak yürütülmüştür. Çalışmada, ekmeklik ve makarnalık buğday genotiplerinin taban ve kıraç koşullarda stoma sayıları bakımından P = 0.01 olasılık düzeyinde farklılıklar gösterdiği; ekmeklik ve makarnalık buğdayların taban koşullardaki stoma sayılarının, kıraca göre daha düşük olduğu saptanmıştır. Çalışmada ayrıca, stoma sayıları bakımından çevre yer x genotip interaksiyonları ekmeklik ve makarnalık buğdaylarda istatistiki olarak önemli düzeyde farklılıklar göstermiştir. Bu çalışma sonunda, stoma sayısının diğer yaprak karakterleriyle birlikte değerlendirilmek suretiyle bitki ıslahı çalışmalarında morfo-fizyolojik bir kriter olarak kullanılabileceği ortaya konmuştur

Variations for the number of stomata in bread and durum wheat genotypes under different environments

Öz

The objective of this study was to investigate the differences among bread wheat and durum wheat genotypes for the number of stomata under high - and low - land conditions in Cukurova Region. The study was conducted at the Research Areas and Laboratories of Cukurova University, Agricultural Faculty, Field Crops Department, and used six bread, five durum wheat genotypes as a material. Also, trials were designed according to the completely randomised blocks with four replicates. In this study, it was found bread and durum wheat genotypes under high- and -low land conditions for the number of stomata showed significant differences at the level of P = 0.01. Also, the numbers of stomata of both species under high- land were less than under low-land conditions. In the study, environment location x genotype interactions for this trait in bread and durum wheat genotypes were statistically different. At the end of the study, it was decided that the number of stomata must be evaluated together with the other leaf traits. Thus, it will be more useful morpho-physiological criteria in plant breeding studies
