Effects of salinities on leaf characteristics and CO2/H2O exchange of mangrove species Kandelia candel seedlings were studied in a pot experiment. The seedlings grown in salinity of 50‰ caused a strong reduction in the rate of growth, but their leaves were black-green, smaller and less expanded or distorted than those of plants in the control and treatment of 25‰. As compared with control plants, leaves of plants treated with salinity of 25‰ were shiny and smooth. Stomatal number and density under the epidermis in leaves were reduced with the increase of salinity. Mesophyll cells in plants grown in salinity...

Possibilities are assessed of the natural regeneration of Douglas fir under conditions of Hůrky Training Forest District, Higher Forestry School and Secondary Forestry School in Písek, in stand 12C7, forest type 3K5. The stand is situated at an altitude of 430 m above sea level in an area with mean annual temperature 7.3-7.5°C and mean annual total precipitation 550-575 mm. Under the stand dominated by Douglas fir (65 years of age), natural regeneration of the mean density of 53,800 seedlings/ha appeared due to lateral light coming from the north. The highest density of Douglas fir natural regeneration was noticed under the stand 10-14 m from the stand...
Effects of varying doses of Frisol on European ash (Fraxinus excelsior L.) planted on spoil banks

Frisol forte (FR F) and Frisol active (FR A) are slow-acting organic fertilisers recommended for reclamation and revitalisation of undeveloped soils and degraded areas. Tentative results of experiments carried out with these products on spoil banks in the CR showed controversial reactions of plants - on the one hand a high mortality of seedlings and a very good growth on the other. Reasons for these disproportions projecting themselves into the welfare of woody plants probably lie in an incorrect dosage of products. Thus, a special long-term experiment was established with the objective to find an optimal dosing to be used in practice for the reclamation...
