“…According to Laurie et al (1991b), there are two possible pathways of metal uptake into root. The first path consists in the dissociation of complex (MeL) in diffusion layer (solution phase) after which the released free ion metal (Me) may be transported to cell root across plasmalemma.…”

“…On the contrary, complexation of Ni by histidine increased its phytoassimilation, but decreased its phytotoxicity (Krämer et al, 1996). According to investigations carried out by Laurie et al (1991b), Von Wiren et al (1996) and Molas (1997), the absorption of metal chelates by plants and their phytotoxicity, including Ni chelates, depends on the chemical nature of the chelating agent as well as on the stability constant of the chelate.…”

“…-10.6 for tomato, which is quite similar to values reported for maize (Zea mays L.) grown in DTPA-containing nutrient solutions (Halvorson and Lindsay, 1977), and for barley (Hordeum vulgare L.) reared in solutions buffered with HEDTA (N-[2-hydroxyethyl] ethyelenedinitrilotriacetate) (Norvell, 1991 ). Laurie et al (1991) also reported Zn deficiency in barley at computed log (Zn 2+) values of ca.…”

“…Similarly, the potential for the supply of metal in the bulk solution to limit rootmetal binding was assessed by comparing the total amount of metal in the bulk exposure solution with the total amount of metal that was sorbed by the root in response to the Me 2+ exposure. Special consideration was given to the potential secondary effects of NTA, which include enhanced metal accumulation via selective and non-selective uptake of the intact metal-chelate complex (Bell et al, 1991(Bell et al, , 2003Laurie et al, 1991) and phytotoxicity (Vassil et al, 1998).…”
