The plant material was micro-propagated from woody plants selected for their ornamental value and hardiness for northern areas of Finland. The observations in the experiments were based on phenological monitoring and survey of plant success. The results revealed significant differences in the success of the different rose genotypes, and the most valuable genotypes were identified. Micropropagation was successfully used as a propagation method and these in vitro propagated roses grew naturally under harsh field conditions. The Rosa 'Tornedal' origins, R . 'Poppius' and R . 'Sipi' were ranked the most suitable cultivars for northern landscaping. Overall, all of the studied roses succeeded fairly well.

The aim of the field experiment was to identify hardy and valuable special tree forms for northern landscaping based on tree phenology and success. All the trees studied revealed some good characteristics and have potential in northern horticulture. B. pubescens f. rubra (red-leaved downy birch) is especially noted for its excellent winter hardiness and showy appearance at every study site. It is a valuable addition to the tree selection for use in northern landscaping.

A factor representing high foliar levels of Ni, Cu and S and low levels of Zn and Mn explained most of the variation in the number of needle age classes (r=−0.67) and tip necrosis (r=0.52). Stomatal chlorosis and other discolourations were explained by a factor representing high foliar concentrations of Ca, Fe, Si and Cl (r=0.74 and r=0.69 respectively). These injury variables also correlated clearly with the modeled SO2 concentration in the air. The cell level injuries studied did not show distinct relations to either the foliar element concentrations or the deposited particles.

Copper and nickel sulphates were mixed with forest mineral soil before seedling planting. The metal levels ranged from 0 to 25 mg Ni kg − 1 dry soil and 0 to 50 mg Cu kg − 1 in dry soil and in combinations of both metals. Current year's needles for element analyses, EDS microanalyses, microscopy and glutathione and peroxidase activity analyses were collected from 1 -5 seedlings per treatment in September. Seedling biomass in controls, Cu25 and Cu50 differed significantly from the Ni25Cu50 treatment. The root/shoot ratio was highest in the Ni5 treatment, indicating good root growth, though the roots were visibly healthier in the Cu25 treatment than in the Ni5 treatment. At higher Ni levels, the condition of roots deteriorated. The proportion of plasmolysed mesophyll cells was highest in the Ni25 treatment. Copper-treated seedlings did not suffer from Cu stress, because no severe injuries were seen in either the roots or the needles in Cu-exposed seedlings. The needle concentrations of Cu increased only slightly due to treatments. Ni accumulation in needles increased with increasing concentrations in soil. Needles of Cu-treated seedlings had less oxidized glutathione than those of Ni-treated seedlings, but the roots had higher, not significantly, peroxidase activity levels. Light-colored, swollen thylakoids were occasionally observed in the Ni25Cu50 treatment, indicating some interaction between Ni and Cu. Ni seemed to cause more oxidative stress to the seedlings than copper, which was manifested as a decreased GSH level and an increased proportion of GSSG in the Ni treatments. Copper together with nickel strongly decreased root growth, the root/shoot ratio being lowest in the Ni25Cu50 treatment. : S 0 0 9 8 -8 4 7 2 ( 9 9 ) 0 0 0 5 7 -X

Research paper thumbnail of Effects of sulphur and heavy metal deposition on foliar chemistry of Scots pines in Finnish Lapland and on the Kola Peninsula

S, Cu and Ni levels rose in the vicinity of the smelter complex in Monchegorsk. K and P concentrations followed the same pattern due to enhanced foliar senescence close to the smelters, whereas those of Mn and Zn decreased in the vicinity of the smelters, possibly because of increased leakage from foliage and soil and antagonistic interactions between Mn, Zn and the emitted elements.

We used plastic filters with different transmittance of UVB radiation to manipulate the environmental conditions. The plants were exposed to (1) attenuated UVB and increased temperature, (2) ambient UVB and increased temperature and (3) ambient conditions. Chlorophyll was extracted from the capitula of the mosses and the content and a/b ratio were measured spectrophotometrically. Seasonal variation of chlorophyll concentration in the mosses was species specific. Temperature increase to 0.5-1 °C and/or attenuation of solar UVB radiation to ca. one fifth of the ambient (on average 12 vs. 59 uW/cm(2)) had little effect on the chlorophyll concentration or its seasonal variation. In the dominant S. lindbergii, UVB attenuation under increased temperature led to a transient decrease in chlorophyll concentration. Altogether, species-specific patterns of seasonal chlorophyll variation in the studied Sphagna were more pronounced than temperature and UVB treatment effects.
