In conifers and other plants with long reproductive cycles, transformed embryogenic tissues can serve as a convenient source of plant material for the testing of insecticidal or fungicidal transgene efficiency. In this report, transgenic embryogenic tissue was obtained after the transformation of somatic embryos of Norway spruce (Picea abies (L.) Karst.) by Agrobacterium tumefaciens with the gus-intron chimeric gene. The stable integration of transgenes was confirmed by PCR and Southern hybridization. The transformation was successful only in a suitable embryogenic cell line sensitive to Agrobacterium. Out of the nine embryogenic...

Notopygus bicarinatus Teunissen, 1953 is parasitoid of web-spinning sawflies of the genus Cephalcia. This species was found near Větrný Jeníkov. The first record from Bohemia including Cephalcia lariciphila as a new additional host. N. bicarinatus oviposit into the larvae of C. lariciphila when borrowing in soil in the late May. The infestation of Cephalcia prepupae is not high and varied within the range of 3.5-6.1% during test period 2003-2005.

Our study aimed to determine morphometric data for wild boar (Sus scrofa) in various areas of the Czech Republic and the potential influence of environment on its body measurements. Three localities with varying agricultural systems and overall landscape structure were selected. Hunted boars were measured for height at the withers, body length, ear length, metatarsal length and weight (depending on the circumstances, either dressed with head, without head, or undressed). We also determined the age of the hunted boars according to teeth development. During 2003-2007, a total 654 boars were examined in various age categories. Body development...
Effect of climatic factors on the dynamics of radial increments of Norway spruce, European beech and sessile oak

Correlations of increment indexes with average monthly temperatures and total monthly precipitation were studied on annual ring series of 455 trees of Norway spruce (Picea abies [L.] Karst.), sessile oak (Quercus petrea Liebl.) and European beech (Fagus sylvatica L.). Data on precipitation from the period 1901-2005 and on temperatures from the period 1931-2005 were used. Statistically significant dependences with correlation coefficients in the range of 0.2-0.5 were confirmed. All tree species react positively to precipitation mainly in June and July. An increase in precipitation by 1 mm when compared with the long-term average...

The Lusatian lignite-mining district (Eastern Germany) is characterized by a high share of marginal post-mining areas. At these sites, crop yield is generally low, and hence, conventional land use systems often fail in terms of reliable and efficient crop production. In this paper the attempt is made to evaluate the production of woody biomass for bioenergy in short rotation coppices (SRC) and alley cropping systems (ACS) with black locust (Robinia pseudoacacia L.) and lucerne (Medicago sativa L.) from the aspect of possible ecological and economic benefits compared to the conventional agricultural recultivation practice. The results...
Evaluation of changes in the landscape management and its influence on animal migration in the vicinity of the D1 motorway in Central Bohemia

J. For. Sci., 2011, 57(7):312-320 | DOI: 10.17221/100/2010-JFS
The article summarizes changes detected in landscape structures and interrelated changes in landscape management surrounding a model section of the D1 motorway (11th-29th km). Biotopes' gradual development was determined based on historical aerial photographs from 1949, 1974, 1988 and 2007. Issues evaluated include especially direct occupation of biotopes and agricultural lands due to constructing industrial areas in the motorway's vicinity, changes in area dimensions of agricultural and forest land, construction of residential complexes and complementary infrastructure. Also investigated was how these transformations and other...
