Ekmeklik buğdayda (Triticum aestivum L.) ilk gelişme döneminde kök ve gövde büyümesi üzerine bazı ağır metal--hormon uygulamalarının etkileri
Bu çalışmada, buğday bitkisinde kurşun (Pb), çinko (Zn) ve kadmiyum (Cd) ağır metalleri ve bu ağır metallerle birlikte uygulanan ABA ve GA3 hormon etkileşimlerinin kök ve sürgün büyümesi üzerine olan etkileri zamana bağlı olarak (5. ve 10. gün) araştırılmıştır. Her üç ağır metalin yüksek konsantrasyonları ve bu ağır metallerle birlikte uygulanan ABA ve GA3 buğday bitkisinin kök ve sürgün büyümesini engellemiştir. Ağır metallerin konsantrasyon ve uygulama süresinin artışına paralel olarak kök ve sürgün büyümesinin engellenmesi arasında bir paralellik olduğu tespit edilmiştir. Çalışılan parametreler üzerinde genel olarak en toksik etkiyi Cd göstermiş, Cd’u Pb ve Zn izlemiştir.

Effects of some heavy metals and heavy metal-hormone ınteractions on the growth of root and shoot on wheat (Triticum aestivum L.) in first vegetation stage
In this study, effects of heavy metals which are lead (Pb), zinc (Zn) and cadmium (Cd), alone, and their interactions with abscisic acid (ABA) and gibberellin (GA3) hormones on the root and shoot growth have been investigated with respect to time (5th and 10th days) in wheat seedlings. All the three heavy metals at high concentrations and interactions of ABA and GA3 hormones with them inhibited the growth of root and stem. It was determined that Cd has shown the most toxic effects and lead and zinc followed.
