Lead Nitrate (Pb (No3)2) Impact on Seed Germination and Seedling Growth of Different Soybean (Glycine Max L.) Varieties

Abstract

The aim of the study was to determine the effects of increasing doses (control, 100, 200, and 400 mg L-1) of lead nitrate (Pb(NO3))2 on seed germination and seedling development of 12 different soybean varieties in the Department of Field Crops laboratory, Faculty of Agriculture, Kahramanmaras Sutcu Imam University in May 2017. It was carried out according to the Completely randomized block design with three replications. In the experiment, some basic germination and seedling growth determining parameters such as germination percentage, germination index, radicle length, plumule length, seedling length, radicle fresh weight, plumule fresh weight, seedling fresh weight, radicle dry weight, plumule dry weight, seedling dry weight, vigor index, and germinated seed number were observed. Based on the characteristics studied in the trial, it was observed that cultivars reacted differently to lead concentrations due to their genotypic structure. Therefore, not only Pb doses were found to have negative effects on some characteristics of varieties, but also, they were also found to have positive effects on some properties of the varieties. These different responses to lead, a heavy metal, show that some kinds of soybeans can be used to resist said heavy metal doses.
