Paclobutrazol is a powerful growth regulator used during the seedling stage to control plant growth and impart desired morphological characteristics. In this study, the effects of paclobutrazol-containing priming applications on the seedling stage of wheat were investigated. Seeds of three wheat cultivars were sown in a solution containing paclobutrazol (PBZ 30) at a dose of 30 mg L-1 for 12 hours. One month after sowing, the seedlings were removed and measured. Local varieties Sarıbuğday and Gökala produced larger seedlings in terms of all traits analysed, while Tosunbey modern wheat variety produced smaller seedling traits. Priming treatments (Hydropriming and PBZ 30) increased seedling root dry weight and chlorophyll content. PBZ 30 application caused a 25% decrease in seedling height compared to the control but increased root wet and dry weight and chlorophyll content. Hydropriming treatment generally increased the above-ground parts (especially seedling height, 8.3 cm). A positive correlation was found between chlorophyll b content and seedling height, number of leaves, seedling stem wet weight and seedling stem dry weight.

Fide döneminde bitki gelişimini kontrol etmek ve istenen morfolojik özellikleri kazandırmak amacıyla kullanılan paclobutrazol güçlü bir büyüme düzenleyicisidir. Çalışmada paclobutrazol içerikli priming uygulamasının buğdayda fide dönemi etkileri incelenmiştir. Üç buğday çeşidine ait tohumlar 30 mg L-1 dozunda paclobutrazol (PBZ 30) içerikli çözeltide 12 saat süreyle bekletilmiş, deneme alanına ekilmiştir. Ekimden bir ay sonra fideler sökülmüş ve ölçümleri yapılmıştır. Sarıbuğday ve Gökala yerel çeşitleri incelenen tüm özellikler bakımından daha büyük fideler oluştururken, Tosunbey modern buğday çeşiti daha küçük fide oluşturmuştur. Priming uygulamaları (Hidropriming ve PBZ 30) fide kök kuru ağırlığı ve klorofil içeriklerini arttırmıştır. PBZ 30 uygulaması kontrole göre fide boyunda yaklaşık %25 oranında azalmaya neden olurken, kök yaş ve kuru ağırlığı ile klorofil içerilerini arttırmıştır. Hidropriming uygulaması genel olarak toprak üstü aksamlarında (özellikle fide boyunda, 8.3 cm) artışlara neden olmuştur. Klorofil b içeriği ile fide boyu, yaprak sayısı, fide sap yaş ağırlığı ve fide sap kuru ağırlığı arasında pozitif korelasyon bulunmuştur.
