The use of peat as a growing media in horticulture is supposed to be reduced due to negative effects of its production on the environment. Interest in development of alternative growing media is therefore increasing and is enhanced by both political pressure and industry demands. Therefore, the influence of 33 growing media on the performance and productivity of two strawberry cultivars were examined in a polytunnel under Nordic conditions (60.7 N). Alternative substrates including fibers of spruce, birch and flax and coffee grounds were tested standalone or in mixes. Peat and coir were included as controls. Additionally, impregnation of the wood fibers with organic and inorganic substances was examined. All investigated growing media received identical fertigation strategies (EC 1.5). The highest average biomass production was observed for plants grown in bare peat; however, the best yield performance was noted for peat mixed with perlite and for coarse spruce fiber. Strawberries grown in these two best performing substrates showed comparable overall productivity, with 272 and 268 g of berries per plant, respectively. Both peat/perlite mix and the coarse spruce fiber had also a similar weight of berries larger than 25 mm, with 210 and 198 g plant-1, respectively. Moreover, improvement of the substrate structure by adding perlite or wood chips may have had a pronounced effect on fruiting performance. When compared to peat with added perlite (which gave the highest berry yield in the experiment; 272 g plant-1), strawberries grown in pure peat produced only 187 g plant-1. Furthermore, impregnation of spruce fiber with humic acid enhanced fruiting performance by increasing the total yield and number of large berries (≥25 mm). Future prospects for this study include establishment of an optimal structure of spruce fiber substrate suitable for strawberry production and development of the fertigation strategy optimized for the new growing media.

Winter hardiness is the main factor limiting pear growing and the use of quince rootstocks under northeastern European climate conditions. Therefore, several cultivar and rootstock trials were performed from 1997 until 2015 at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. Investigations of pear cultivars were conducted in 2005-2015. Twelve cultivars on QS1 rootstock were tested with the goal of finding an optimal replacement for cultivar ‘Conference’, which is not sufficiently winter hardy in the Baltic countries. The cultivar ‘Mramornaja’ showed desirable characteristics based on winter hardiness, productivity and fruit quality. Rootstock breeding was based on a winter hardy Cydonia × oblonga population and resulted in 3 registered rootstocks of K series in Lithuania. K series rootstocks were compared with QMA, QMC, Sydo, QS1, and Pyrus × communis. According to tree growth control and productivity only K11 was equal to QMA and the same as QS1. Other rootstock testing included Cydonia and Pyrus clonal and seedling rootstocks. ‘Pyrodwarf’ and OH×F333 rootstocks were too vigorous. QMC, Sydo and BA29 exhibited poor winter hardiness. The search for both pear cultivars and rootstocks adapted to northeastern European climatic conditions must be continued.

The interest in old cultivars of apple trees, their fruit and processed products is growing worldwide. Studies on the qualitative and quantitative composition of biological compounds are important for the evaluation of the quality and nutritional properties of apple fruit. A variation in the qualitative and quantitative composition of triterpenic compounds was found in the fruit of apple cultivars included in the collection of National Plant Genetic Resources. A high-performance liquid chromatography (HPLC) analysis showed that the fruit of the cultivar ‘Birutės pepinas’ had the highest total amount (5.17 ± 0.86 mg g-1) of triterpenic compounds. Higher total amounts of triterpenic compounds were also found in the fruit of apple cultivars ‘Tabokinė’ and ‘Panemunės baltasis’ (3.72 ± 0.57 and 4.25 ± 0.17 mg g-1, respectively). By the quantitative composition, triterpenic compounds in apple fruit were ranked in the following order: ursolic acid > oleanolic acid > corosolic acid > betulinic acid. The old apple cultivars ‘Birutės pepinas’, ‘Panemunės baltasis’ and ‘Tabokinė’ included in the collection of National Plant Genetic Resources have a potential for cultivation in industrial orchards and for the use of their apples, and processed apple products as natural functional foods rich in triterpenic compounds and adapted for medical purposes, including the prevention of various diseases. Key words: apple, old cultivars, triterpenic compounds.
