Table 2.

Root length (cm), root weight (mg), shoot weight (mg) and chlorophyll content (mg g⁻¹ FW) in two different cultivars of grey poplar (Populus ×canescens Aiton Sm.) plants after 2 and 10 days of growth in the presence of different concentrations of Cd. Data are presented as the mean ± SD (n = 3). Values followed by the same letter(s) within the same column are not significantly different according to Tukey’s test (p ˂ 0.05).
