Salix clones

Clonal differences in Cd uptake are independent of whether the plant is cultivated in nutrient solution or soil however, the relation between clones in accumulation of other metals, such as Cu and Zn, may differ depending on these two media (Greger et al., 2001). In the case of Cu and Zn, the presence of soil may trigger roots to initiate rhizosphere processes (Stoltz and Greger, 2002), which is absent in solution culture. It is therefore important to investigate differences in root rhizosphere mechanisms between Salix clones. 

Clones used in this investigation and their properties to accumulate Cd, Zn or Cu shown as concentration of the metal in shoot and roots rfter metal treatment Data are from a screening where different Salix clones were treated with 112 mg Cd, 18.9 mg Cu or 441 mg Zn m ... 

Succinic acid showed very little variation in all clone exudates in all treatments, but the concentration of H+ (pH) and other organic acids and level of hydrophilic peptides were shown to vary within the rhizosphere at different soil metal levels and between Salix clones (Tables 2 ). Differences were also found when comparing metals.
