properties were determined.
Investigations were carried out on twenty five wheat ( T. aestivum L.) varieties, including twelve of winter and thirteen of springwheat varieties
, Skagen, and Smuga and springwheat: Bombona, Brawura, Trappe, Hewilla, Kandela, Katoda, Łagwa, Monsun, Ostka Smolicka, Parabola, Tybalt, Werbena, and Żura were grown at the experimental field of the Institute of Soil Science and Plant Cultivation — State

Soil and meadow grass were sampled in the whole territory of Lithuania in 1992–2000. For the laboratory experiment, spring
wheat Triticum aestivum L. “Nandu” was used because its root system type is similar to that of perennial meadow grass. The 137Cs soil-to-plant transfer factor of spring wheat was determined and the results were compared with the predicted values using
a compartment model of soil-to-plant transfer and with the results of the field experiment. The results of comparing the measured
and calculated transfer factor using the model show rather good coincidence, however, the calculated values were overestimated.
The reason for overestimation can be that the uptake rate is not influenced only by the soil-to-plant transfer. The results
of the model experiment (from 0.005 m2·kg−1 to 0.053 m2·kg−1) are close to those of the field measurements for grass (from 0.013 m2·kg−1 in 1992–1995 to 0.10 m2·kg−1 in 1999–2000).
Twelve biological-matrix, agricultural/food reference materials, Corn Stalk (Zea Mays) (NIST RM 8412), Corn Kernel (Zea Mays) (NIST RM 8413), Bovine Musele Powder (NIST RM 8414), Whole Egg Powder (NIST RM 8415), Microcrystalline Cellulose (NIST RM 8416), Wheat Gluten (NIST RM 8418), Corn Starch (NIST RM 8432), Corn Bran (NIST RM 8433), Whole Milk Powder (NIST RM 8435), Durum Wheat Flour (NIST RM 8436), Hard Red Spring Wheat Flour (NIST RM 8437) and Soft Winter Wheat Flour (NIST RM 8438) were developed. They were characterized with respect to elemental composition via two extensive international interlaboratory characterization campaigns providing 303 reference and informational concentration values for 34 elements (Al, As, B, Ba, Br, Ca, Cd, Cl, Co, Cr, Cs, Cu, F, Fe, Hg, I, K, Mg, Mn, Mo, N, Na, Ni, P, Pb, Rb, S, Sb, Se, Sr, Ti, V, W, Zn) of nutritional, toxicological, and environmental significance. These products are available to the analytical community, for quality control of elemental composition analytical data, from the Standard Reference Materials Program, National Institute of Standards and Technology, Gaithersburg, MD, USA.

Two wheat cultivars (
L. cv. Chinese Spring and Cappelle Desprez) differing in drought stress tolerance were treated with two concentrations of cadmium (10
to investigate whether there is also any difference in their heavy-metal tolerance. Overpressured layer chromatography (OPLC) with off-line fluorescence detection was used to monitor cadmium stress-induced changes in the polyamine content of wheat seedlings. Significant differences were found between the spermidine (Spd) and putrescine (Put) content of the two wheat cultivars. The Spd content of the moderately drought-tolerant Chinese Spring increased both in shoots and roots at the higher Cd concentration compared with the control whereas in the drought-sensitive Cappelle Desprez the Spd level was reduced by both Cd treatments. Put content increased with the amount of Cd to which the roots of Chinese Spring wheat were exposed. In the Cappelle Desprez cultivar the Put content of both organs was higher at both Cd concentrations compared with the control.
