Key factors of shoot organogenesis induction from seedling shoot apices were examined. The plastid DNA analysis was used as a molecular-genetic tool. The trnL-trnF region of chloroplast DNA was tested by PCR-RFLP method; furthermore, the chloroplast microsatellite region Pt41093 was also analysed. All the tested individuals from the studied population matched the Pinus uncinata subsp. uliginosa haplotype. In bog pine, regeneration and development of axillary shoots were significantly enhanced in the presence of 5 g・l-1 activated charcoal on the WV5 and WPM (Duchefa) media. The highest proliferation (28-30%) of short shoots (brachyblasts) was observed on the WV5 medium in the absence of benzyladenine (BA) or at its low concentration only (0.1 mg・l-1).

These Norway spruce progenies are compared with the control estimated from tables. The control was overperformed in all measured growth parameters. Heights of selected spruce progenies at the age of 26 years ranged from 9.2 m (K10) to 10.7 m (K2). The control height was 6.4 m. In the evaluation of diameters, progeny K4 showed the best mean dbh (13.7 cm) while the progeny K17 was rated as the thinnest (10.5 cm). We compared these data with the control diameter of 6.5 cm. The mean volumes of selected material varied from 0.097 m3 (K9) to 0.047 m3 (K17) while the kontrol presented 0.0172 m3.

(waterlogged sites) and in the Zemska locality (Low Tatras Mts.) (well-drained sites). The methods of linear correlation and regression analysis were used to quantify the relationships between the aboveground and belowground parameters. In waterlogged sites, a signifiant correlation (r = 0.60) was found between the stem diameters and the horizontal width of root plate, calculated average width of root plate, theoretical surface of root plate and visible surface of root plate. A medium correlation was found out between the stem diameters, tree height and the vertical radius of root plate. Similarly, a medium correlation was also determined between the tree height, width and length of crown and the horizontal width of root plate, average calculated width of root plate, theoretical surface of root plate and visible surface of root plate in spruce trees growing in waterlogged sites. In well-drained sites, was found out a medium correlation between the stem diameters and the horizontal width of root plate, partial vertical radius of root plate, average calculated width of root plate, theoretical surface of root plate and visible surface of root plate. A somewhat lower correlation was observed between the tree height and the vertical radius of root plate, average calculated width of root plate and theoretical surface of root plate in spruce trees growing in well-drained sites. In both sites, was found out a slight correlation between the aboveground parameters and the thickness of root plates; and no correlation was determined between the crown proportion index and root plate parameters.

Abstract: The paper summarizes results from the analyses of Norway spruce (Picea abies [L.] Karst.) stands managed by the Forest Administration in Horní Maršov, Krkonoše National Park (KRNAP), which are affected by decline and by yellowing of the assimilatory apparatus. Forest stands included in the analyses were aged 10-80 years and originated from both artificial and natural regeneration. Analyses of root systems were combined with analyses of soil chemical properties and assimilatory organs, weather conditions and emissions. The analyses showed that affected trees had small and malformed anchoring root systems with a lower number of horizontal roots and a lower number of fine roots of lower vitality (high proportion of dead fine roots), which penetrated only through the uppermost humus horizons. Root systems of affected trees are infested by the honey fungus (Armillaria sp.), which colonizes anchor roots. Neither root nor bole rots were detected so far.

In view of instant decline in the rainfed hill agro-forestry system the present study was undertaken in the hilly villages of Uttarakhand state of India with the major objective to assess the status and effects of various factors on this centuries old indigenous agro-forestry system. The survey documented a total of 26 herbaceous food crop species and 21 woody species that were raised by farmers in the selected villages of Uttarakhand. A total of 37 plant species available in the agro-forestry system and used for curing various ailments by traditional healers were also documented during the survey. The major cereals produced by farmers were Oryza sativa L., Echinochloa frumentoacea Link., Eleusine coracana (L.) Gaertner and Triticum aestivum L. The indigenous system of cropping was locally called as Baranaja that revolved around the production of > 12 varieties of crops. Besides food, the species grown in the agro-forestry system were used for multiple purposes. Water scarcity, migration of youth in search of employment and changing socio-economic and climatic conditions were some of the major reasons for declining agro-forestry system and abandoning the agricultural land.
