Özet
Bu çalışma, Bu-Ter tere (Lepidium sativum L.) tohumlarına uygulama olarak ağır metal kurşunun farklı konsantrasyonları ve vermikompost uygulamasının çimlenme ve fide gelişim parametrelerine etkisi belirlenmesi amacıyla tesadüf parselleri deneme desenine göre üç tekrarlamalı olarak yürütülmüştür. Çalışma Siirt Üniversitesi Bahçe Bitkileri Bölümü Laboratuvarında gerçekleştirilmiştir. Denemede kullanılan uygulamalar 0, 500, 1000, 1500 ppm, vermikompost, 500 ppm+vermikompost, 1000 ppm+vermikompost, 1500 ppm+vermikompost olarak belirlenmiştir. Petrilere tohumlar eklenmiş ve uygulamalar yapıldıktan sonra 22±1 °C sıcaklığa ayarlanmış etüve yerleştirilmiştir. Çalışma sonunda çimlenme yüzdesi (%), ortalama çimlenme zamanı (gün), çimlenme hızı (çimlenme indeksi), vigor indeksi gibi çimlenme parametreleri ile fide boyu (cm), hipokotil çapı (cm), kök uzunluğu (cm), yaş ağırlık ve kuru ağırlık (mg) parametreleri değerlendirilmiştir. Elde edilen sonuçlara göre, Pb konsantrasyonu arttıkça çimlenme yüzdesinin azaldığı belirlenmiştir. En düşük çimlenme yüzdesine 1500 ppm Pb uygulamasında %60.75 olduğu belirlenmiştir. Ortalama çimlenme süresi bakımından, vermikompost uygulamasının Pb ile birlikte uygulanmasının 500 ppm Pb ve 1500 ppm Pb uygulamasındaki ortalama çimlenme süresini düşürdüğü ancak 1000 ppm Pb uygulamasında ise negatif etki yaparak ortalama çimlenme süresini arttırdığı belirlenmiştir. Çimlenme indeksinin en düşük 1500 ppm Pb uygulamasında 9.900 olduğu görülmüştür. En yüksek çimlenme enerjisinin 93.333 ile vermikompost uygulamasında, en düşük ise 500 ppm kurşun uygulamasında 2.667 olarak belirlenmiştir. Vigor indeksi, boy uzunluğu, hipokotil çapı ve kök uzunluğunu en yüksek vermikompost uygulamasında olduğu görülmüştür. Fide yaş ve kuru ağırlığı bakımından uygulamalar arasındaki farklılığın istatistiksel olarak önemli olmadığı belirlenmiştir. Sonuç olarak Bu-Ter tere tohumunda uygulamaların belirli düzeylerde etkili olduğu ve elde edilen sonuçlar ışığında ilerde tere genotip ve çeşitleri üzerine yapılacak olan daha geniş çaplı çalışmalara referans olacağı düşünülmektedir.
This study was carried out in three replications according to the randomized plot design in order to determine the effects of different concentrations of heavy metal lead and vermicompost application on germination and seedling growth parameters as an application of Bu-Ter cress (Lepidium sativum L.) seeds. The study was carried out in laboratory of Siirt University Faculty of Agriculture, Department of Horticulture. The applications used in the experiment were determined as 0, 500, 1000, 1500 ppm, vermicompost, 500 ppm+vermicompost, 1000 ppm+vermicompost, 1500 ppm+vermicompost. Seeds were added to the petri dishes and after the applications were made, they were placed in an oven set at 22±1 °C. At the end of the study, germination parameters such as germination percentage (%), average germination time (day), germination rate (germination index), vigor index, and seedling length (cm), hypocotyl diameter (cm), root length (cm), fresh weight and dry weight (mg) parameters were evaluated. According to the results obtained, it was determined that the germination percentage decreased as the Pb concentration increased. It was determined that the lowest germination percentage was 60.75% in 1500 ppm Pb application. In terms of average germination time, it was determined that the application of vermicompost together with Pb decreased the average germination time in 500 ppm Pb and 1500 ppm Pb applications, but increased the average germination time by having a negative effect in 1000 ppm Pb application. The lowest germination index was found to be 9.900 in 1500 ppm Pb application. The highest germination energy was determined as 93.333 in vermicompost application, and the lowest in 500 ppm lead application was determined as 2.667. Vigor index, height, hypocotyl diameter and root length were found to be highest in vermicompost application. It was determined that the difference between the applications in terms of seedling fresh and dry weight was not statistically significant. As a result, it is thought that the applications in Bu-Ter cress seeds are effective at certain levels and in the light of the results obtained, it is thought that it will be a reference for wider studies on the cress genotype and varieties in the future.
