The aim of this paper is to analyze the level of sustainable development (SD) in voivodeships of Poland in the year 2010. The level of SD of voivodeships in Poland was estimated in three dimensions: economic, social and environmental with two methods: soft modeling and TOPSIS. On the basis of sustainable development theory, a soft model has been built to show relations between economy, society and environment as well as their impact on sustainable development. The analysis of results shows optimal relations between the level of economic, social and environmental development, which will allow future generations to make use of existing resources. Application of the soft modeling and TOPSIS method had enabled classifi cation of regions in regard of economy level, society and environment so as the comparison of the results of grouping achieved using this methods. The study was completed with data of Polish Statistic Offi ce collected in 2010.

W pracy oceniano zmienność fenotypową u 10 linii wsobnych żyta ozimego wyselekcjonowanych z różnych odmian uprawnych i form hodowlanych. Różnice pomiędzy liniami dotyczyły cech związanych z produktywnością roślin: długości źdźbła i kłosa, krzewistości, liczby ziaren z kłosa, masy 1000 ziaren, plonu ziarna z rośliny, intensywności fotosyntezy netto i transpiracji, a także liczby chloroplastów w mezofilu oraz zawartości chlorofilu. Wybrane linie wsobne żyta charakteryzowały się dużym zróżnicowaniem pod względem wymienionych cech i wykazywały wartości skrajne. Spośród analizowanych linii wyróżniała się linia J74, która miała najwyższe wartości dla większości cech (długość kłosa, liczba ziaren z kłosa i roślin, ulistnienie oraz aktywność fotosyntetyczna), co predysponuje ją do zastosowania w hodowli wysokoproduktywnych, heterozyjnych odmian żyta.

Accumulation of various osmolytes was examined in plants of sugar beet cv. Janus grown under two soil water treatments: control (60% of the field water capacity; FWC) and drought (30–35% FWC). The water shortage started on the 61st day after emergence (DAE), at the stage of the beginning of tap-roots development and was imposed for 35 days. Osmotic potential of sugar beet plant organs, particularly tap-roots, was decreased significantly as a consequence of a long-term drought. Water shortage reduced univalent (K+, Na+ ) cations concentrations in the petioles and divalent (Ca2+, Mg2+) ions level in the mature and old leaves. Cation concentrations in the taproots were not affected by water shortage. The ratio of univalent to divalent cations was significantly increased in young leaves and petioles as a consequence of drought. Long-term water deficit caused a significant reduction of inorganic phosphorus (Pi) concentration in young and old leaves. Under the water stress condition, the concentration of proline was increased in all individual plant organs, except proline concentration in the youngest leaves. Drought treatment caused a significant increase of glycine betaine content in shoot without any change in tap-roots. Glucose concentrations were significantly increased only in tap-roots as the effect of drought. In response to water shortage the accumulation of sucrose was observed in all the examined leaves and tap-roots. Overall, a long-term drought activated an effective mechanism for osmotic adjustment both in the shoot and in the root tissues which may be critical to survival rather than to maintain plant growth but sugar beet organs accumulate different solutes as a response to water cessation.

Generation of superoxide anion (O2) and peroxidase activity were significantly increased in bean leaves infected with incompatible and compatible pathogens: Botrytis fabae and Botrytis cinerea, respectively, but the induction was greater on direct inoculation with B. fabae, than with B. cinerea. A slightly higher O2 level was also detected in the parts of leaves surrounding the inoculation side. Overproduction of Ó2 was observed earlier than the increase in peroxidase activity. Pretreatment of the leaves with methyl jasmonate enhanced both O2 production and peroxidase activity following inoculation with B. cinerea. Induction of superoxide dismutase activity after the infection was less pronounced than changes in Ó2 level. The differences in the rate of NADH oxidation in the extracts from control and inoculated leaves, correlated with the differences in the rate of O2 production. The results indicate thatCte level is one of the essential factors responsible for the difference in the interactions between bean plant and compatible and incompatible pathogens.
