Bu çalışmada, kışlık ekmeklik buğdayda bayrak yaprak klorofil içerikleri ile tarımsal özellikler ve membrane termostabilitesi, membrane hasar indeksi ve bayrak yaprak oransal su içeriği arasındaki ilişkiler incelenmiş olup; çalışma, 2010-2011 yetiştirme sezonunda Gümüşhane Üniversitesi, Şiran Mustafa Beyaz MYO uygulama alanında yapılmıştır. Genotiplerin klorofil içeriği, klorofil metre ile çiçeklenme başlangıcı ZGS 60 ve erken süt olum ZGS 73 dönemlerinde ölçülmüştür. Genotiplerin korofil içerikleri ortalaması ZGS 60 döneminde 45.6 SPAD birimi olarak ölçülmüş olup; genotiplere göre 39.1 line 51 ile 54.0 line 42 arasında değişim göstermiştir. ZGS 73 döneminde ise genotiplerin klorofil içeriği ortalaması 41.8 olup; genotiplere göre 35.2 line 27 ile 50.9 line 44 arasında değişmiştir. Genotiplerin klorofil kaybı, ortalama %8.3 olup; genotiplere göre %1.7 line 75 ile %19.2 line 32 arasında dağılım göstermiştir. Her iki ölçüm döneminde, klorofil içerikleri ile başakta dane sayısı ve başak verimi gibi verim ana komponentleri arasında istatistiksel olarak önemli ilişkiler bulunmuştur. Klorofil içerikleri ile klorofil kaybı arasındaki ilişki, ZGS 60’da olumlu, ZGS 73’te olumsuz bulunmuştur. Sonuçlar, kışlık buğdayda bayrak yaprak klorofil içeriği tayininin ıslah programlarında verim komponentleriyle ilişkisi bakımından önemli bir seleksiyon kriteri olduğunu göstermektedir

In this study, relationships among flag leaf chlorophyll contents of some winter wheat genotypes, agronomical traits, and some physiological characters such as canopy temperature, membrane thermal stability, membrane injury, and relative water content of flag leaf were evaluated. The study was conducted in the Application and Research Area of Siran Vocational School of Gumushane University in the growth season of 2010-2011. Chlorophyll content of genotypes were measured by a portable chlorophyll meter at the start of anthesis ZGS 60 and the early milky stage ZGS 73 . The mean chlorophyll content of the tested genotypes at ZGS 60 was 45.6 as SPAD unit, and ranged from 39.1 for line 51 to 54.0 for line 42. Chlorophyll content as the mean of all genotypes at ZGS 73 was 41.8 as SPAD unit. Mean chlorophyll content of the genotypes at this growth stage ranged between 35.2 for line 27 and 50.9 for line 44. The mean pigment loss was the percent of 8.3 as an average of all genotypes. The chlorophyll loss ranged between 1.7 % for line 75 and 19.2 % for line 32. The statistically significant correlations between chlorophyll contents and main yield components like grain number per spike and spike yield were obtained at both measuring stages. The significant correlation between chlorophyll loss and chlorophyll content was positive at ZGS 60, but negative at ZGS 73. These results show that determination of flag leaf chlorophyll content in winter wheat is important selection criteria for yield components in breeding programs.
