Porównanie odporności na suszę dwóch odmian pszenicy

The effects of drought stress on changes in the relative water content, in levels of photochemical efficiency and chlorophyll content and in activities of antioxidative enzymes of second leaves of winter wheat (Triticum aestivum L.) cultivars Mironovská and Estica were compared. In one set, control plants were regularly watered, the other set of plant was subjected to water deficit period since 11th day to 18th day of plants life-span. The activity of all antioxidative enzymes and content of β-carotene increased, relative water content, total chlorophyll content and photochemical efficiency decreased after treatment in both cultivars. In the case of Estica the values of antioxidative enzymes activity was higher than in the case of Mironovská. It is therefore possible to assume that Estika is capable of dealing with higher levels of active oxygen species created during drought stress.This might enabled it compensate the effects of drought stres more effectively.W pracy porównano wpływ suszy na względną zawartość wody, wydajność fotochemiczną PS II i zawartość chlorofilu oraz aktywność enzymów antyoksydacyjnych w 2. liściu pszenicy ozimej odmian Mironowska i Estica. Rośliny grupy kontrolnej regularnie podlewano, drugą grupę poddano działaniu suszy glebowej w okresie od 11. do 18. dnia wegetacji. Zabieg ten zwiększył aktywność enzymów antyoksydacyjnych i zawartość β-karotenu, przy równoczesnym obniżeniu względnej zawartości wody, stężenia chlorofilu i wartości wydajności fotochemicznej PS II liści obydwóch odmian. Aktywność antyoksydantów była wyższa u odmiany Estica w porównaiu z Mironowską. W związku z tym wydaje się możliwe, iż Estica charakteryzuje się zwiększoną wydajnością unieszkodliwiania reaktywnych form tlenu wytwarzanych w zwiększonych ilościach podczas deficytu wody, co może przyczyniać się do tolerowania stresu suszy glebowej przez tę odmianę

Financial competencies as investigated in the nursing field: Findings of a scoping review

Aim(s): This study aims to map the extent of the research activity in the field of financial competencies and nursing and identify main patterns, advances, gaps, and evidence produced to date. Background: Financial competencies are important indicators of professionalism and may influence the quality of care in nursing; moreover, these competencies are the basis of health care sustainability. Despite their relevance, studies available on financial competencies in the nursing field have not been mapped to date. Evaluation: A scoping review was guided according to (a) the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Review and (b) the Patterns, Advances, Gaps and Evidence for practice and Research recommendations framework. Key issue(s): A total of 21 studies were included. Main research patterns have been developing/evaluating the effectiveness of education programmes and investigating the nurse's role in the context of financial management, challenges and needs perceived by them, and tool validation to assess these competencies. The most frequently used concept across studies was ‘financial management competencies’ (n = 19). Conclusion(s): The sparse production of studies across countries suggests that there is a need to invest in this research field. Implications for nursing management: Nurses with managerial roles should invest in their financial competencies by requiring formal training both at the academic and at the continuing education levels. They should also promote educational initiatives for clinical nurses, to increase their capacity to contribute, understand, and manage the emerging financial issues
