THE EFFECT OF SOME CULTIVATION CONDITIONS ON PROPERTIES OF LEAVES OF THE CONTAINER-PRODUCED SPECIES ALNUS GLUTINOSA (L.) GAERTN

Abstract JEZDINSKÝ, A., ŘEZNÍČEK, V: The eff ect of some cultivation conditions on properties of leaves of the containerproduced species Alnus glutinosa (L.) Plants diff er in their reactions to unfavourable environmental conditions and the eff ect of the acting factors directly and indirectly results in changes in a number of plants organs. The leaves are vegetative organs and as such they are completely exposed to external conditions. Most markedly these conditions aff ect the assimilative organs. The objective of the present study was to evaluate the eff ect of four substrates and two sites diff ering in light intensity on the leaf morphology of the model plant species Alnus glutinosa (L.) Gaertn. The used substrates were the commercial peat-bark substrate (RKS II), sand and bark substrate. With these substrates the soil conditioner TerraCottem was applied at a rate of 5 g per one litre of the substrate. The experimental plants were grown in 2-litre containers. The focus of evaluations of the individual treatments was on some leaf properties. TerraCottem showed that it had a positive eff ect also on the leaf area ratio and on leaf effi ciency. The number of leaves varied. The eff ect of the substrate and of the light intensity was identical; the latter parameter was strongly correlated with leaf weight. The shape of the leaves (leaf length/width ratio) and the SLA index responded to the diff erent light intensities. Other parameters were calculated from the results of the measured values which specifi ed in greater detail the eff ect of the year, media, hydro absorbent and light. Treatments A3 (1 697.60 mm 2 ) and a conrol (1 708.10 mm 2 ) had the smallest leave area. These two treatmens signifi cantly statistically diff ered frome those in the shade location.

Žánry ve vybraných filmech bratří Coenů

The main purpose of this paper is to analyze film genres, their conventions, and their subsequent use in films Fargo and No Country for Old Men by the Coen Brothers. In the initial part of the paper the introduction and function of genre theory is presented. Specific concepts and definitions are further described. In the second part the Coen Brother's biography and their work are presented. The last part considers analysis of films with special attention being paid to the usage of genre conventions.Hlavním cílem této práce je poskytnout analýzu filmových žánrů, jejich konvencí a jejich následovné využití ve filmech Fargo a Tahle země není pro starý natočených bratry Coeny. V úvodní části práce je představena filmová teorie. Dále jsou popsány specifické koncepce a definice. Druhá část se věnuje biografii a dílu bratří Coenů. Poslední část zahrnuje analýzu filmů se zaměřením na jejich použití žánrových konvencí.Katedra anglistiky a amerikanistik

The effect of some cultivation conditions on properties of leaves of the container-produced species Alnus glutinosa (L.) Gaertn

Plants differ in their reactions to unfavourable environmental conditions and the effect of the acting factors directly and indirectly results in changes in a number of plants organs. The leaves are vegetative organs and as such they are completely exposed to external conditions. Most markedly these conditions affect the assimilative organs. The objective of the present study was to evaluate the effect of four substrates and two sites differing in light intensity on the leaf morphology of the model plant species Alnus glutinosa (L.) Gaertn. The used substrates were the commercial peat-bark substrate (RKS II), sand and bark substrate. With these substrates the soil conditioner TerraCottem was applied at a rate of 5 g per one litre of the substrate. The experimental plants were grown in 2-litre containers. The focus of evaluations of the individual treatments was on some leaf properties. TerraCottem showed that it had a positive effect also on the leaf area ratio and on leaf efficiency. The number of leaves varied. The effect of the substrate and of the light intensity was identical; the latter parameter was strongly correlated with leaf weight. The shape of the leaves (leaf length/width ratio) and the SLA index responded to the different light intensities. Other parameters were calculated from the results of the measured values which specified in greater detail the effect of the year, media, hydro absorbent and light. Treatments A3 (1 697.60 mm2) and a conrol (1 708.10 mm2) had the smallest leave area. These two treatmens significantly statistically differed frome those in the shade location. In the 2005 year the highest values were measured at the treatment B1 (41.22 m2.kg−1). Next year the values of the SLA were similar

Effect of Nutrient Supply on Some Selected Parameters of Sweet Pepper (Capsicum annuum L. cv. ‘HRF’) Transplants

In the trial the effect of nitrogen deficiency and potassium surplus on the dry weight, photosynthetic activity (A), transpiration (E), stomatal conductance (gs) and water use efficiency (WUE) were examined. The macroelement content of aboveground parts were analysed, too. The plants were grown in pots filled by pure Sphagnum peat. The top-dressing started in the 3-leave stage of plants, with different solution (every irrigation): control treatment: 0.28 g N, 0.097 g P (0.22 g P2O5), 0.42 g K (0.50 g K2O) per litre; nitrogen-deficiency: 0.097 g P (0.22 g P2O5), 0.42 g K (0.50 g K2O) per litre; potassium surplus: 0.28 g N, 0.097 g P (0.22 g P2O5), 0.83 g K (1.0 g K2O) per litre. The transplants grown in the commercial fertilization technology (control treatment) almost in every evaluated parameters shown average value. The potassium surplus resulted significantly higher transpiration activity (2.58 mmol H2O. m−2 . s−1) and photosynthetic activity (11.54 μmol CO2. m−2 . s−1) than the nitrogen deficiency (E: 1.91 mmol H2O. m−2 . s−1 and A: 9.01 μmol CO2. m−2 . s−1), but without significant differences with control treatment. The N, P and K content of aboveground parts was significantly lower in the nitrogen deficiency treatment, than in the case of the potassium surplus, too. The effect of treatments on the dry weight of the plants, the stomatal conductance and the water use efficiency was not proven statistically
