Heavy metal contamination in soils can adversely affect seed germination and seedling growth of most plants. This research was conducted to determine the effects of different doses (0, 100, 200, 400 and 800 mg L-1) of Ni (nickel), Cd (cadmium), Pb (lead), Cr (chromium) and Hg (mercury) on seed germination and seedling growth of sorghum. The study was conducted in laboratory conditions at the Agricultural Faculty of Akdeniz University in 2017. Sorghum cv. N48×Early Sumac was used as the plant material. In the research, germination rate (GR), relative germination index (RGI), mean germination time (MGT), relative vigor index (RVI), relative root length (RRL), relative shoot length (RSL), root fresh weight (RFW) and shoot fresh weight (SFW) were measured during germination and seedling growth to determine the effects of heavy metals. The results showed that both germination and seedling growth properties were adversely affected by heavy metals. In addition, while the negative effect of cadmium on germination properties was limited, it had serious negative effects on seedling characteristics of sorghum. Increasing heavy metal doses adversely affected all investigated properties. In conclusion, all heavy metals including Hg and Cd had negative effect on germination and seedling growth of sorghum in the study.
Topraklarda ağır metal kirlenmesi çoğu bitkinin tohum çimlenmesini ve fide gelişimini olumsuz etkileyebilir. Bu araştırma, Ni (nikel), Cd (kadmiyum), Pb (kurşun), Cr (krom) ve Hg (civa)’ nın farklı dozlarının (0, 100, 200, 400 and 800 mg L-1) sorgumun çimlenme ve fide gelişimi üzerine etkilerini belirlemek amacıyla yürütülmüştür. Araştırma, 2017 yılında Akdeniz Üniversitesi Ziraat Fakültesi’nde laboratuvar koşullarında yürütülmüştür. N48×Early Sumac sorgum çeşidi bitki materyali olarak kullanılmıştır. Bu araştırmada ağır metallerin etkisini belirlemek için çimlenme oranı (ÇO), nispi çimlenme indeksi (NÇİ), ortalama çimlenme süresi (OÇS), nispi canlılık indeksi (NCİ), nispi kök uzunluğu (NKU), nispi sap uzunluğu (NSU), kök yaş ağırlığı (KYA) ve sap yaş ağırlığı (SYA) özellikleri incelenmiştir. Araştırma sonuçları ağır metallerin hem çimlenme hem de fide özelliklerini olumsuz etkilediğini göstermiştir. Ayrıca, kadmiyumun çimlenme özellikleri üzerine olumsuz etkisi sınırlı düzeydeyken, fide özellikleri üzerinde ciddi olumsuz etkileri olmuştur. Ağır metal dozlarındaki artış da incelenen özellikleri olumsuz etkilemiştir. Sonuçta, bu çalışmada kullanılan ağır metallerin sorgumun incelenen özellikler üzerinde olumsuz etkiye sahip olmakla birlikte, özellikle Hg ve Cd diğerlerinden daha fazla olumsuz etkiye neden olmuştur.
