In order to evaluate the potential of common cyclamen (Cyclamen purpurascens Mill.) for the use for foliage ornamentals sixteen genotypes were collected from different regions in Slovenia. Cyclamen plants were classified into four groups based on their foliage characteristics: green, marbled, semi-silvery and silvery group. Leaves were analyzed in autumn and winter. Colour characteristics were colorimetrically evaluated, chlorophyll and carotenoid content was measured spectrophotometrically and anthocyanin and flavonol content were determined with the use of HPLC-PDA-MSn. A detailed analysis revealed that cyclamen leaves grouped into various types differed in numerous parameters. Colour measurements exposed changes between autumn and winter leaves and also among different genotypes. Marbled and semi-silvery genotypes tended to develop more red and pink colouration in autumn, whereas during the winter period the red and pink colouration was only observed in marbled genotypes. The latter were also characterized by high levels of anthocyanins. Semi-silvery, green and marbled genotypes accumulated high levels of chlorophyll (a, b, total) particularly in autumn leaves. Leaves of green and marbled cyclamen types contained high levels of different quercetin and myricetin compounds, as well as higher laricitrin and kaempferol levels compared to semi-silvery and silvery genotypes. Oppositely, isoharmnetine-3-rutinoside and neohesperidine concentrations prevailed in marbled and silvery genotypes.

Acta Biologica Slovenica (former Biološki vestnik) is Slovene scientific journal, which has been publishing for more than half of the century. It publishes peer reviewed papers from the field of biology twice a year. Biological library distributes the journal to 188 institutions in Slovenia and worldwide, receiving other scientific journals for exchange.

Strawberry (Fragaria ananassa Duch.) is one of the most intensively produced fruit crop. We have therefore questioned the effects of biofumigation and soil heating on arbuscular mycorrhizal fungi (AMF) colonisation, strawberry growth and strawberry yield in pot experiments compared with untreated soil and chemical fumigation with dazomet. Three different Brassicaceae species (Brassica juncea, Eruca sativa, Sinapis alba) were used as biofumigant plant green manure and soil heating was applied to simulate soil solarisation. Half of the plants were inoculated with indigenous arbuscular mycorrhizal fungi inoculum. Dazomet displayed the greatest inhibitory effects on AMF establishment. With one exception (E. sativa) among the uninoculated plants, the treatments significantly decreased the mycorrhizal colonisation parameters compared with the untreated control. In addition, the frequencies of Glomus spp. were lower for strawberry plants from biofumigant treatments than from the control. Despite the reduced AMF colonisation, biofumigation resulted in a higher fruit number and mass of leaves. Therefore, it represents a non-chemical soil fumigation method that should be applied in sustainable strawberry production. Mycorrhizal fungi alleviated negative effects of disinfection in inoculated treatments.

One of the key actions identified by the Water Framework Directive (WFD; 2000/60/EC) is to develop ecological assessment tools and carry out a European intercalibration (IC) exercise. The aim of the Intercalibration is to ensure that the values assigned by each Member State to the good ecological class boundaries are consistent with the Directive’s generic description of these boundaries and comparable to the boundaries proposed by other MS. In total, 83 lake assessment methods were submitted for the 2nd phase of the WFD intercalibration (2008-2012) and 62 intercalibrated and included in the EC Decision on Intercalibration (EC 2013). The intercalibration was carried out in the 13 Lake Geographical Intercalibration Groups according to the ecoregion and biological quality element. In this report we describe how the intercalibration exercise has been carried out in the Alpine Lake Macrophyte group.
