Nanoparticles have unique properties and are used in fertilizers. Seed priming can improve seed germination and seedling growth. Various nanoparticles are used in seed germination and growth of various plant species and varieties. This experiment was conducted to investigate the effect of TiO2 nanoparticles on plant morphology when applied from leaves at different growth stages of sunflower and used as seed priming material. Before the start of the field experiment the seeds were soaked in 20 mg Lˉ¹ for 8 hours. The experiment was laid out in a randomized complete block design using five TiO2 treatments with three times replicated doses of 0 (control), 20 mg Lˉ¹ TiO2 treatments to seeds, and at different growth stages. Plant height reached its highest level with TiO2 treatments to seeds in both years. The maximum yield value observed in TiO2 treatments to seeds in the first year of the experiment. Results revealed that TiO2 application to seeds and at V-4 stage is the most effective stages on sunflower growth.

Nanopartiküller benzersiz özelliklere sahiptir ve gübrelerde kullanılır. Tohumları ön uygulamalara tabi tutumak, tohum çimlenmesini ve fide büyümesini iyileştirebilir. Çeşitli bitki türlerinin ve çeşitlerinin tohum çimlenmesinde ve büyümesinde çeşitli nanopartiküller kullanılmaktadır. Bu deney, TiO2 nanopartiküllerinin ayçiçeğinin farklı büyüme aşamalarında yapraklardan uygulandığında ve tohuma ön işlem uygulama malzemesi olarak kullanıldığında bitki morfolojisi üzerindeki etkisini araştırmak için yapılmıştır. Tarla denemesine başlamadan önce tohumlar 8 saat boyunca 20 mg Lˉ¹ içinde ıslatılmıştır. Deney, 0 (kontrol), tohumlara 20 mg Lˉ¹ TiO2 uygulamaları ve farklı büyüme aşamalarında üç kez tekrarlanan dozlarla beş TiO2 uygulaması kullanılarak tesadüf blokları deneme düzeninde yürürlmüştür. Bitki boyu her iki yılda da tohumlara TiO2 uygulamasıyla en yüksek seviyeye ulaşmıştır. En yüksek verim değeri denemenin ilk yılında tohumlara TiO2 uygulamalarında gözlenmiştir. Sonuçlar, tohumlara TiO2 uygulamasının ve V-4 aşamasında yapraktan uygulamanın ayçiçeği büyümesi üzerinde en etkili aşamalar olduğunu ortaya koymuştur.
