Abstract

The green synthesis of zinc oxide nanoparticles (ZnO-NPs) has garnered significant attention due to their potential to enhance plant growth. In this study, the effects of ZnO-NPs synthesized using thyme extract (Tv-ZnO-NPs) on wheat plants were investigated by applying seven different concentrations ranging from 250 to 5000 mg L⁻¹. The aim was to evaluate the effects of these nanoparticles on plant growth and to provide insights into their potential roles in improving growth performance. Tv-ZnO-NPs were characterized by SEM, FTIR, and XRD analyses, revealing an average particle size of 19.72 nm. To assess their effects on the growth of wheat seedlings, the synthesized ZnO nanoparticles (Tv-ZnO-NPs) were applied via foliar spraying. Following the application, a significant increase in seedling height was observed at all treatment concentrations compared to the control group. Additionally, a significant increase in chlorophyll content was noted at low concentrations (250 and 500 mg L⁻¹), whereas no statistically significant change was detected at higher concentrations (≥4000 mg L⁻¹). However, in plants exposed to Tv-ZnO-NPs at concentrations between 250 and 3000 mg L⁻¹, statistically significant changes in dry/fresh weight ratio and a marked increase in Zn²⁺ content were observed. These findings indicate that Tv-ZnO-NPs positively affect the growth and development of wheat seedlings. Furthermore, a clear dose-response relationship between nanoparticle concentration and plant response was established. This shows the agricultural potential of plant-derived nanoparticles and emphasizes the need to optimize the appropriate dose for achieving maximum agricultural benefits.

Özet

Çinko oksit nanoparçacıklarının (ZnO-NP'ler) yeşil sentezi, bitki büyümesini artırma potansiyelleri nedeniyle önemli ölçüde dikkat çekmiştir. Bu çalışmada, kekik ekstresi kullanılarak sentezlenen ZnO-NP'lerin (Tv-ZnO-NP'ler) buğday bitkisi üzerindeki etkileri, 250 ila 5000 mg L⁻¹ arasında değişen yedi farklı konsantrasyon uygulanarak araştırılmıştır. Amaç, bu nanoparçacıkların bitki büyümesi üzerindeki etkilerini değerlendirmek ve büyüme performansını artırmadaki potansiyel rollerine ilişkin öngörüler sağlamaktır. Tv-ZnO-NP'ler, ortalama 19,72 nm parçacık boyutu ortaya koyan SEM, FTIR ve XRD analizleri ile karakterize edilmiştir. Buğday fidelerinin büyümesi üzerindeki etkileri değerlendirmek amacıyla sentezlenen çinko oksit nanoparçacıkları (Tv-ZnO-NP'ler) yapraktan püskürtme yöntemiyle uygulanmıştır. Uygulamanın ardından, tüm uygulama konsantrasyonlarında kontrol grubuna kıyasla fide boyunda anlamlı bir artış gözlemlenmiştir. Ayrıca, düşük konsantrasyonlarda (250 ve 500 mg L⁻¹) klorofil içeriğinde anlamlı bir artış meydana gelmiş; buna karşın, daha yüksek konsantrasyonlarda (≥4000 mg L⁻¹) istatistiksel olarak anlamlı bir değişim tespit edilmemiştir. Bununla birlikte, . Bununla birlikte, 250 ila 3000 mg L⁻¹ konsantrasyonları arasında Tv-ZnO-NP'lere maruz kalan bitkilerde kuru/yaş ağırlık oranında istatistiksel olarak anlamlı değişiklikler ve Zn²⁺ içeriğinde belirgin bir artış gözlenmiştir. Bu sonuçlar, Tv-ZnO-NP’lerin buğday fidelerinin büyüme ve gelişimini olumlu yönde etkilediğini ortaya koymaktadır. Ayrıca, nanoparçacık konsantrasyonu ile bitki tepkisi arasında açık bir doz-tepki ilişkisi saptanmıştır. Bu bulgu, bitki kaynaklı nanoparçacıkların tarımda kullanım potansiyelini göstermekte ve en yüksek tarımsal verimin sağlanabilmesi için uygun dozun dikkatle belirlenmesi gerektiğini vurgulamaktadır.
