CHLORELLA VULGARİS UYGULAMASININ FARKLI TAHIL TÜRLERİNDE MORFOLOJİK PARAMETRELER ÜZERİNE ETKİSİ

Öz

Dünya çapında artan gıda talebi nedeniyle, tahıl üretiminde sürdürülebilir ve çevre dostu uygulamalara olan ihtiyaç giderek önem kazanmaktadır. Bu çalışma, Chlorella vulgaris mikroalginin arpa (Hordeum vulgare), buğday (Triticum aestivum) ve yulaf (Avena sativa) bitkilerinde morfolojik gelişim parametreleri üzerindeki etkilerini değerlendirmek amacıyla yürütülmüştür. Denemede Chlorella vulgaris 1g kg-1 dozunda arpa, buğday ve yulaf bitkisine topraktan uygulanmıştır. Elde edilen bulgulara göre, Chlorella vulgaris uygulaması bütün çeşitlerde bitki boyunu anlamlı düzeyde artırmıştır. Bitki boyu, arpa için %8.69, buğday için %39.25 ve yulaf için %12.42 oranında artmıştır. Benzer şekilde, kök uzunluğu arpa, buğday ve yulaf bitkilerinde sırasıyla %45.5, %23.08 ve %26.52 oranlarında artmıştır. Bitki yaş ağırlığında ise arpa için %25,14, buğday için %37.48 ve yulaf için %47.06 oranlarında artış belirlenmiştir. Uygulama ayrıca bitki kuru ağırlığını da önemli ölçüde artırmış, buğday, arpa ve yulaf bitkilerinde sırasıyla %43.24, %26.74, ve %20.18 oranlarında yükselme sağlamıştır. Kök yaş ağırlığında ise sırasıyla %18.75 (arpa), %19.11 (buğday) ve %25.67 (yulaf) oranlarında artış sağlanmıştır. Kök kuru ağırlığında bu artışlar sırasıyla %20.10 (arpa), %19.66 (buğday) ve %23.05 (yulaf) olarak ölçülmüştür. Sonuç olarak bulgular, Chlorella vulgaris’in sürgün ve kök aksamında biyokütle artışını desteklediğini göstermekte, mikroalglerin toprakla doğrudan uygulanmasının bitki gelişimini destekleyebileceğini ve biyogübre olarak uygulanmasının sürdürülebilir tarıma katkı sağlayabileceğini ortaya koymaktadır.

The Effect of Chlorella vulgaris Application on Morphological Parameters in Different Cereal Species

Öz

Due to the increasing global demand for food, the need for sustainable and environmentally friendly practices in cereal production is becoming increasingly important. This study was conducted to evaluate the effects of the microalga Chlorella vulgaris on the morphological development parameters of barley (Hordeum vulgare), wheat (Triticum aestivum), and oat (Avena sativa) plants. In the experiment, Chlorella vulgaris was applied to the soil at a dose of 1 g kg⁻¹ for each plant species. The findings revealed that Chlorella vulgaris application significantly increased plant height in all varieties: by 8.69% in barley, 39.25% in wheat, and 12.42% in oats. Similarly, root length increased by 45.5% in barley, 23.08% in wheat, and 26.52% in oats. Fresh plant weight increased by 25.14% in barley, 37.48% in wheat, and 47.06% in oats. The application also significantly enhanced dry plant weight, with increases of 43.24% in wheat, 26.74% in barley, and 20.18% in oats. Root fresh weight increased by 18.75% (barley), 19.11% (wheat), and 25.67% (oats), while root dry weight increased by 20.10%, 19.66%, and 23.05%, respectively. In conclusion, the results indicate that Chlorella vulgaris supports biomass growth in both shoot and root systems. These findings suggest that direct soil application of microalgae can promote plant development and that its use as a biofertilizer could contribute to sustainable agriculture.
