The content and composition of glucosinolates in green parts of mustard plant iSinapis alba L.), at different stages of plant development were analysed. Four mustard varieties: Salvo, Metex, Ascot and Nakielska were taken under consideration. It was stated that in green parts of mustard sinalbin was dominating component of glucosinolates, but also glucotropeolin and small amounts of glucobrassicanapin apeared. The content of these compounds changes during vegetation and it is different in particular plant organs. Biological activity of mustard glucosinolates towards cabbage aphid was also studied. The correlation between the content of glucosinolates in plant and its susceptibility to aphid iBrevicoryne brassicae L.) infestation was checked. It was found that higher level of glucosinolates in plant caused some limitation of this pest development. Also the activity of water and alcohol extracts from mustard leaves was tested in relation to cabbage aphid. Disadvantageous influence of these extracts on aphids' survival was observed and this effect depended on extracr's concentration.

Praca zawiera analizy i oceny skutków wybranych regulacji polskiego prawa dotyczących gospodarki przestrzennej, zwłaszcza planowania przestrzennego. Różni się od poprzednich raportów położeniem większego nacisku na bariery blokujące naprawę wadliwego systemu publicznego zarządzania przestrzenią. Praca nie jest próbą oceny prawa pod względem jego poprawności jurydycznej i legislacyjnej.
