Приведена характеристика альгоценозов обрастаний каменистых субстратов и макрофитов среднего течения р. Сылва. Проанализированы многолетние (1992-2012 гг.) изменения альгофоры перифитона. Показано, что видовой состав, численность и биомасса фитоперифитона зависят от гидролого-гидрохимических условий в местах отбора проб. Для эпифитона и от морфо-физиологических особенностей субстрата-макрофита: погруженные Potamogeton lucens L., P. perfoliatus L., P. gramineus L. и P. pectinatus L., Myriophyllum spicatum L. и полупогруженные Nuphar lutea (L.) Smith, Petasites hybridus (L.) Gaertn., Mey. et Sxherb., Equisetum fluviatile (L.).

Chlorophyll content of wheat (Triticum aestivum L. ‘Mericopa’) and corn (Zea mays L. ‘Merit’) treated with the herbicide fluridone {1-methyl-3-phenyl-5-[3-(trifluoromethyl)-phenyl]-4(1H)-pyridinone} and grown under high light intensity (10.8 klux), was markedly reduced. Corn and wheat germinated from seeds treated with 10 uM fluridone and grown for 6 days were almost completely bleached. Under low light intensity (108 lux) the influence of fluridone on chlorophyll production was greatly reduced. Under very low light intensity (21.5 lux) this influence was almost completely lost. The effect of light on the activity of fluridone suggests that the inhibition of carotenoid production may represent the mode of action of this herbicide. This study shows that the carotenoid content of wheat or corn drops dramatically when these plants are treated with fluridone.
