“…Although foliar uptake for M. spicatum had been indicated for K (Carignan, 1985) and Rb (Waisel et al, 1982), some preliminary data had suggested that root uptake from the sediments was also important for 137 Cs (D.W. Evans and P.J. Cooke as discussed in Kelly and Pinder, 1996).…”

“…Carignan (1985) suggested that M. spicatum transports K absorbed from the water column to the roots where it is released into the sediments to displace NH 4 C which can augment N availability. Transport of foliar absorbed Rb to roots has also been reported (Waisel et al, 1982). If a similar process occurs for Cs, then some of what appears to be loss could instead be translocation to roots.…”

“…Observed concentration ratios are computed from the data of Pinder et al (2005). measures of variation in foliar uptake rates among submerged macrophytes. Adamec (1997) reported a greater than 14-fold difference in K absorption rates among macrophyte species, and Waisel et al (1982) reported a 4-fold difference in Rb adsorption rates. Much of the difference in patterns between U. inflata and M. spicatum can be attributed to the 4-fold greater estimate of k for M. spicatum (Table 3).…”

“…Foliar absorption of potassium (K) has been either demonstrated or indicated for submerged macrophytes by Mickle and Wetzel (1978), Barko (1982), Huebert and Gorham (1983), Barko et al (1988), Shardendu and Ambasht (1991) and Adamec (1997). Foliar absorption of sodium (Na) and rubidium (Rb) has also been demonstrated by Winter (1961) and Waisel et al (1982), but foliar absorption of cesium does not appear to have been experimentally demonstrated for submerged macrophytes.…”

“…In a study of submerged macrophytes, Waisel, Agami & Shapira (1982) showed that the rates and direction of translocation of ^*Rb differed markedly between species. However, in an uptake period of 24 h, the amount translocated from root to stem and leaves did not exceed 5 % in Potamogeton perfoliatus, the species which showed the most rapid transport.…”

SUMMARYA bioassay method has been developed to test for potassium deficiency in forest trees; it is based on the metabolic uptake by excised roots of ^*Rb from 5 x 10~® M rubidium chloride solution during a period of 15 min. Betula pubescens Ehrh. seedlings were grown in sand culture supplied with Hewitt's nutrient solution containing K at concentrations between 1 and 200 mg T^ A negative curvilinear relationship was demonstrated between uptake by the seedlings of ^*Rb from the rubidium chloride solution and the concentration of K previously supplied in the growth medium. When roots of intact plants were immersed in ^*Rb-labelled solution for 15 min, less than 1 % of *®Rb taken up was translocated to the shoots. A similar response curve, relating ^®Rb uptake to K supplied to growing plants, was demonstrated when Picea sitchensis (Bong.) Carr seedlings were grown in peat culture with K added at 0 to 400 mg T^ In three field trials of the bioassay, roots were excised from P. sitchensis and Pinus contorta Douglas ex Loud, growing on peat or peaty gley plots where different amounts of fertilizer had been added to give a range of degrees of K deficiency or from unfertilized, control plots. The patterns of ^®Rb uptake by excised roots indicated that the method is potentially useful for the rapid determination of K deficiency in forest trees.
