“…Higher retention in roots and a lower percentage of translocation to the shoots is a typical feature in plants grown at deficient nutrient supply, such as zinc (Cakmak and Marschner, 1990;Chandel and Saxena, 1985;Santa Maria et al 1988), Fe (Ramani, 1988), or phosphorus (Cogliatti and Clarkson, 1983), and also for organic solutes, such as vitamins (Mozafar and Oertli, 1992).…”

SummaryThe effect of Ca on the absorption and translocation of Mn, Zn and Cd in excised barley roots was studied using a multi-compartment transport box technique. A radioisotope (54Mn, 65Zn or HsmCd)-labelled test solution was supplied to the apexes of excised roots and the distribution pattern in the roots was examined in the absence or presence of Ca. Results obtained were as follows.Addition of Ca to the test solution reduced the absorpIion of Mn and inhibited drastically its translocation in excised roots. With increasing concentrations of Ca in test solutions, its inhibitory effects on the absorption and translocation of Mn became severe.Similar results were observed for the absorption and translocation of Zn. Ca in the test solution decreased the absorption and inhibited drastically the translocation of Zn; as in the case of Mn, higher concentrations of Ca had severe effects on these functions.It was also evident that the addition of Ca to the test solution reduced the absorption of Cd at all levels of Cd concentration (1, 10, and 100#M). Cd absorption decreased with increasing concentrations of Ca in the test solution. However, Ca accelerated the translocation of Cd in excised roots supplied with test solutions containing up to 10#M Cd. At 100gM Cd, addition of Ca caused a negligibly small acceleration of Cd translocation.The accelerating effect of Ca on Cd translocation, especially "xylem exudation", decreased markedly with the addition of 2,4-dinitrophenol, but not with the addition of chloramphenicol or p-chloromercuribenzene sulphonic acid. When barley plants were supplied with only CaSO 4 during the entire growing period, that is, plants were not supplied with nutrient solution on the last day of this period, Ca had no accelerating effect on Cd translocation in excised roots.
