The objective of this work was to apply selected genetic markers to verify the genetic purity of bog pine (Pinus uncinata subsp. uliginosa) individuals from the Borkovicka blata population in order to initiate in vitro cultures from them. 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...

The present paper evaluates the height, diameter and stem volume of parental tree progenies. 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...

The aboveground parameters and the parameters of root plates in uprooted Norway spruce trees (Picea abies [L.] Karst.) were measured in the Hnile Blata locality (the High Tatras Mts.) (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...
Decline of Norway spruce in the Krkonoše Mts.

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...
Status of an indigenous agro-forestry system in changing climate: A case study of the middle Himalayan region of Tehri Garhwal, India

The agro-forestry system is one of the best known indigenous practices for livelihood. 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...
