A b s t r a c t. The plant reactions on Al-stress include i.a. change of the surface area of the roots, which in the physicochemistry of plants characterizes the transport of water and ions through the root. The object of this study is the specific surface area of the roots of plants which are tolerant to aluminium, such as rye. Plants of rye were grown in a nutrient solution for 14 days at pH 4.5 in the presence of Al 3+ ions of concentration 10, 20, and 40 mg dm . The control plants were grown continuously at pH 7 or pH 4.5 without Al 3+. The apparent surface area and adsorption energy of the plants roots were determined from water vapour adsorption -desorption data. The apparent surface area of roots growing in the aluminium was (with respect to control) statistically significantly lower. There were no statistically significant differences in the apparent surface area of the roots which grew in pH 7, pH 4.5 without Al 3+. The average water vapour adsorption energy of the root surface, under stress conditions decreased. In the roots grown in the presence of Al +3

In the present study, the influence of humic acid (HA) molecular fractions (HA < 30 kDa and HA > 30 kDa) on enhancing the tolerance of seedlings of soybean [Glycine max (L.) Merr.] Progres and Nawiko cultivars to salt stress (50 mM NaCl) was investigated. HA were extracted from mountain fen soil and then were separated into two molecular fractions by membrane filtration and characterized by diffusion coefficient (Dapp), electrolytic conductivity (κ) and electrophoretic mobility (Ue). The following biometric parameters of tested plants were determined: total leaf area, height of plants, fresh and dry mass of the over ground part and roots as well as length of shoots cells and length of stomas. The chlorophyll content in ground tissue as well as the macro and microelements content in tested plants also were determined. The results showed that the κ, Ue and Dapp for HA > 30 kDa were lower than these for HA < 30 kDa. Adding NaCl caused increase κ and decrease Dapp and Ue. The salt stress caused a major decrease in biometric parameters in tested plants. HA > 30 kDa reduced the uptake of macro and microelements in the soybean Progres cultivar. In soybean Nawiko cultivar, it caused significant uptake of Fe and Zn. Soybean cultivars showed strong reaction to salt stress. HA molecular fractions reduced or eliminated the influence of the salt stress. However, HA > 30 kDa was more effective than HA < 30 kDa, due to its properties.
