Abstract:

 Salinity is a critical environmental factor that adversely affects crop growth and productivity. This study aimed to evaluate the effects of gibberellic acid GA3 on germination, shoot length, root length, and biomass of two wheat cultivars Demirhan and Fazılbey under varying levels of salt stress 0, 5, and 10 dSm NaCl. GA3 was applied at concentrations of 100 and 200 ppm to assess its potential in alleviating the adverse effects of salinity. The results revealed that GA3 significantly improved germination percentage, shoot length, and root length in both cultivars, with the Demirhan cultivar showing more pronounced responses under higher salt stress. A biplot analysis highlighted the interaction between GA3 treatment, salinity levels, and cultivar performance, confirming the positive role of GA3 in mitigating the detrimental effects of salinity. These findings suggest that GA3 can be an effective strategy for enhancing wheat growth in saline soils. Further studies are recommended to optimize GA3 concentrations and evaluate its long-term effects under field conditions.

 Tuzluluk, bitki büyümesini ve verimliliğini olumsuz yönde etkileyen kritik bir çevresel faktördür. Bu çalışma, gibberellik asidin GA3 farklı tuz stresi seviyeleri 0, 5 ve 10 dSm NaCl altında iki buğday çeşidinin Demirhan ve Fazılbey çimlenme yüzdesi, sürgün uzunluğu, kök uzunluğu ve yaş ve kuru ağırlık üzerindeki etkilerini incelemeyi amaçlamıştır. GA3, tuzluluğun olumsuz etkilerini azaltmak için 100 ve 200 ppm konsantrasyonlarda uygulanmıştır. Sonuçlar, GA3ün her iki çeşitte de çimlenme yüzdesini, sürgün uzunluğunu ve kök uzunluğunu önemli ölçüde iyileştirdiğini, Demirhan çeşidinin daha yüksek tuz stresi altında daha belirgin tepkiler gösterdiğini ortaya koymuştur. Biplot analizi, GA3 uygulaması, tuzluluk seviyeleri ve çeşit performansı arasındaki etkileşimi vurgulayarak, GA3ün tuzluluğun zararlı etkilerini azaltmadaki olumlu rolünü doğrulamıştır. Bu bulgular, GA3ün tuzlu topraklarda buğday büyümesini arttırmak için etkili bir strateji olabileceğini göstermektedir. GA3 konsantrasyonlarını optimize etmek ve tarla koşulları altında uzun vadeli etkilerini değerlendirmek için daha fazla çalışma yapılması önerilmektedir.
