Kuraklık Stresinin Karabuğday (Fagopyrum esculentum) Yaş ve Kuru Fide Ağırlığı Üzerine Etkisinin Belirlenmesi

Abstract

Polygonaceae familyasına ait olan Fagopyrum esculentum (Karabuğday) bitkisi önemli tıbbi bitkilerden birisidir. Karabuğday bitkisi de birçok bitki gibi iklim değişikliği sonucu meydana gelen ve ekolojik faktörlerden biri olan kuraklıktan etkilenmektedir. Bu araştırmada kuraklık stresinin karabuğday bitkisinin yaş ve kuru fide ağırlığı üzerine etkileri ele alınmıştır. Deneme 2023 yılında Düzce Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü Laboratuvarlarında, tesadüf parselleri deneme desenine göre üç tekerrürlü olarak kurulmuştur. Karabuğday tohumlarına kuraklık stresine tepkisini ölçmek için polyethylene glycol’un dört farklı konsantrasyonu uygulanmış olup elde edilen veriler kontrol faktörüne göre kıyaslanmıştır. Denemede fide yaş ağırlığı ve fide kuru ağırlığı ortalamaları arasında istatistiksel olarak önemli derecede farklılık görülmüştür. Sonuçlara göre karabuğday bitkisinin yaş ve kuru fide ağırlıklarının kuraklıktan etkilendiği gözlemlenmiştir. Fide yaş ve kuru ağırlığının stres arttıkça düştüğü; en fazla yaş ve kuru fide ağırlığının kontrol faktöründe ve en düşük yaş ve kuru fide ağırlığının 60 mg/l PEG içeren çimlendirme ortamında meydana geldiği görülmüştür.

Determination of The Effect of Drought Stress on Fresh and Dried Seedling Weight of Buckwheat (Fagopyrum esculentum)

Abstract

Fagopyrum esculentum (Buckwheat) plant, which belongs to the Polygonaceae family, is one of the important medicinal plants. Buckwheat plant, like many plants, is affected by drought, which is one of the ecological factors that occurs as a result of climate change. In this research, the effects of drought stress on fresh and dry seedling weight of buckwheat plant were discussed. The experiment was established in 2023 at Düzce University Faculty of Agriculture Department of Field Crops Laboratories, according to the randomized complete block design, with three replications. Four different concentrations of polyethylene glycol were applied to buckwheat seeds to measure their response to drought stress, and the data obtained were compared according to the control factor. In the experiment, a statistically significant difference was observed between the average seedling fresh and dry weight. According to the results, it was observed that the fresh and dry seedling weights of buckwheat plant were affected by drought. Seedling fresh and dry weight decreased as stress increased; It was observed that the highest fresh and dry seedling weight occurred in the control factor and the lowest fresh and dry seedling weight occurred in the germination medium containing 60 mg/l PEG.
