تالاب بینالمللی فریدونکنار در جنوب شرقی مناطق کم ارتفاع دریای خزر قرار دارد و با وسعتی معادل 5427 هکتار در محدوده جغرافیایی 52 درجه و 31 دقیقه طول شرقی و 36 درجه و 45 دقیقه عرض شمالی واقعشده است. نمونههای گیاهی از 6 ایستگاه جمعآوری و به طریق علمی خشک و پرس و با کمک کلیدهای تخصصی شناسایی و شکل زیستی و کوروتیپ آنها مشخص گردید. در این مطالعه که در سالهای 91 تا 92 و در چهارفصل سال ان...
Industrial wastewater treatment comprises several processes to fulfill the discharge permits or to enable the reuse of wastewater. For tannery wastewater, constructed wetlands (CWs) may be an interesting treatment option. Two-stage series of horizontal subsurface flow CWs with Phragmites australis (UP series) and Typha latifolia (UT series) provided high removal of organics from tannery wastewa...
Two major emergent macrophytes, Phragmites australis and Typha angustifolia, show a clear zonation with respect to water depth, i.e., P. occupies shallower than T. angustifolia. However, the reasons for this interspecific difference is unclear. Therefore, study focused on features that enable angustifolia survive at greater depths australis. In both outdoor greenhouse experiments, did not deepe...
The results of the comparative-morphological analysis Typha astrakhanica are presented. It has been established that according to morphological signs, plants from southern reservoirs (Volga delta) Astrakhan oblast differ those given in botanical literature, T. angustifolia, australis, domingensis, grossheimii. described species membranous, rounded at apex upward-directed lobes (ears) vagina ste...
Restoration efforts take place at large scales to improve the ecological value of degraded, modified river deltas. To anticipate on implications using dredged, estuarine sediment restore wetlands in deltas, we studied development Typha latifolia (cattail) and Phragmites australis (common reed) two designated dredged sediments, virgin Holocene clay (clay) eroded (mud), under different water leve...
In order to address energy efficiency issues in the building sector, we conducted this study which focuses on optimization of mechanical characteristics Typha concrete for its use load-bearing structures buildings. The fact that buildings are very energy-intensive makes it essential develop new forms construction based bioclimatic architecture and valorization certain materials considered as wa...
The article presents data on the study of effect technogenically polluted wastewater digital biomass and NDVI parameters phytoremediants. Analysis plant growth development was carried out Phragmites australis (Cav.) Trin. ex Steud. (obtained by in vitro method), Typha angustifolia L. T. latifolia from seeds). All species were grown combination with various microorganisms under influence wastewa...
