Abstract
The effects of hot water treatments of carrot seeds on seed-borne fungi, germination, emergence and yield were studied. Seeds infected with Alternaria dauci were hot water treated at different temperatures.

Abstract
Potential response of forest soils to sulphur deposition in the Norwegian-Russian border area in the surroundings of the Pechenganikel smelters, the major sulphur emitters in the northern Europe, has been assessed with the PROFILE model. The release rate of base cations due to weathering range from 0.05 to 0.28 kmol(c)/ha/yr in the 0 - 50 cm soil layer, thus demonstrating the high sensitivity of the coarse and thin podzols studied. Calculated steady-state BC/Al values are significantly lower than the presumed critical value of 1, which indicate possible negative effect on vegetation through soil acidification. According to the model calculations future sulphur deposition have to be very low in order to stop the ongoing acidification and prevent vegetation damage. However, model assumptions, uncertainty in input data and critical chemical values applied implies that modelling results must be interpreted carefully
Abstract
Contamination of atmosphere and soils was found to be accompanied by the active participation of S, Ni, Cu and Fe in the biological cycle in the area adjacent to \"Petchenganickel\" group of smelting works. The content of Ni, Cu and S in pine needles near the works is as high as 0,7-1; 0,4-0,5 and 40-60 mmol/kg respectively, these values for metals being by an order of magnitude higher than those in unpolluted areas. With increase in the age of trees the content of N, P, K, Mg and S in pine needles decreases and the content of Ca, Al, Fe and Mn increases; accumulation of Ni and Cu in pine needles is usually observed near the smelting works.
Abstract
The objective structure of parameters of soil acidity and cation exchange properties of podzols affected by the emission of the Pechenganikel factory (the Kola Peninsula) is revealed. The multiparametric analysis of soil properties and the traditional correlation analysis complement one another. They point to the complex character of interrelations between soil properties in conditions of progressing human-induced acisification.
