Nanopriming Uygulamalarının Kavun (Cucumis melo L.) Tohumlarında Çıkış ve Fide Kalitesine Etkisi

Öz

Bitkisel üretimde geniş kullanım alanı bulan nanomateryallerin, priming uygulamalarındaki etkileri daha önceki çalışmalarda belirlenmiştir. Kavun (cv. Kırkağaç) tohumlarına, hidropriming, organik priming ajanı olarak Ferula elaeochytris sakız ekstraktı (0.2 g l⁻¹) ve Tagetes erecta taç yaprak ekstraktı (4 g l⁻¹), nanopriming ajanı olarak ZnO+CaNO₃ (0.002 g l⁻¹, 0.004 g l⁻¹ ve 0.01 g l⁻¹) ve ZnO+Ca₃PO₄ (0.002 g l⁻¹, 0.004 g l⁻¹ ve 0.01 g l⁻¹) uygulamaları yapılmıştır. En yüksek çıkış oranı %97 ile hidropriming ve CaNO₃ (0.01 g l⁻¹) nanopriming uygulamalarından elde edilmiştir. Ortalama çıkış süresi ZnO+Ca₃PO₄ (0.01 g l⁻¹) nanopriming uygulamasında 115 saat ile en kısa sürede tamamlanmıştır. Fide kalite parametrelerinden yaş ve kuru ağırlık içeriği (sırasıyla 14.48 mg, 2.01 mg) ZnO+CaNO₃ (0.01 g l⁻¹) nanopriming uygulamasında en yüksek bulunmuştur. En yüksek fide boyları hidropriming uygulamasında 55.60 mm ve ZnO+Ca₃PO₄ (0.002 g l⁻¹) nanopriming uygulamasında 54.20 mm olarak belirlenmiştir. En yüksek klorofil içeriği 43.33 SPAD değeri ile ZnO+Ca₃PO₄ (0.004 g l⁻¹) nanopriming uygulamasından elde edilmiştir. Yaprak boyu, yaprak eni ve yaprak alan değerleri Tagetes erecta organik priming uygulaması ve ZnO+CaNO₃ (0.004 g l⁻¹) nanopriming uygulamasında öne çıkmıştır. Tüm nanopriming uygulamaları kontrol grubuna kıyasla istatistiksel olarak önemli bulunmuş ve ekim öncesi tohum uygulamalarında kullanılabileceği belirlenmiştir (p<0.05).

The Effect of Nanopriming Treatments on Emergence and Seedling Quality in Melon (Cucumis melo L.)

Abstract

Nanomaterials have found wide use in plant production and their effects in priming treatments have been determined in different species. Melon (cv. Kırkağaç) seeds were treated with hydropriming, Ferula elaeochytris gum extract (0.2 g l⁻¹) and organic priming agent Tagetes erecta petal extract (4 g l⁻¹), nanopriming agent as ZnO+CaNO₃ (0.002 g l⁻¹, 0.004 g l⁻¹ and 0.01 g l⁻¹) and ZnO+Ca₃PO₄ (0.002 g l⁻¹, 0.004 g l⁻¹ and 0.01 g l⁻¹). The highest emergence percentage was obtained from hydropriming and ZnO+CaNO₃ (0.01 g l⁻¹) nanopriming treatments as a 97%. Mean emergence time was completed in the shortest time with 115 hours in ZnO+Ca₃PO₄ (0.01 g l⁻¹) nanopriming treatment. Among the seedling quality parameters, the fresh and dry weight content (14.48 mg, 2.01 mg, respectively) was determined to be the highest in ZnO+CaNO₃ (0.01 g l⁻¹) nanopriming treatment. It was determined that the highest seedling height in hydropriming treatment as a 55.60 mm and ZnO+Ca₃PO₄ (0.002 g l⁻¹) nanopriming treatment as a 54.20 mm. The highest chlorophyll content was obtained from ZnO+Ca₃PO₄ (0.004 g l⁻¹) nanopriming treatments with 43.33 SPAD. Leaf length, leaf width and leaf area values were prominent in Tagetes erecta organic priming treatments and ZnO+CaNO₃ (0.004 g l⁻¹) nanopriming treatment. All nanopriming treatments were found to be statistically significant compared to the control group and it was determined that they could be used in pre-sowing seed treatments (p<0.05).
