Numerical analysis of the taxa belonging to the genus Rosularia (DC.) Stapf was carried out to find out their phenetic relationship. Data from different disciplines viz. general, pollen and seed morphology, chemistry and distribution pattern were used. As a result of cluster analysis two distinct groups are formed. Out of which one group consists of R. sedoides (Decne.) H. Ohba and R. alpestris...

In the course of the study of collected specimens from West Azerbaijan province (NW Iran), Prometheum rechingeri (Crassulaceae) is reported for the first time from Iran. Based on recent phylogenetic and morphological studies in Crassulaceae family, genus Prometheum was considered as independent genus. So far, two species viz. P. pilosum (under Sedum pilosum), and P. sempervivoides (under S. se...

The studies were carried out on the territory of State National Natural Park «Kulsai Lakes», located northern macroslope Kungei Alatau ridge. main dominant species plant communities southern slopes mountains with bedrock outcrops at altitudes 1600-2000 m a. s. l. have been identified. These are shrubs - Juniperus sabina, Cotoneaster melanocarpus, Ephedra intermedia, Artemisia gmelinii. Dominant...

Photosynthetic characteristics and induction of crassulacean acid metabolism (CAM) by drought stress were investigated in Sedum album, Sedum stoloniferum and Rosularia elymaitica from Crassulaceae. Titratable acidity, malate content, phosphoenolpyruvate carboxylase (PEPC) activity and gas exchange parameters were determined in plants at the end and beginning of the photoperiod. Results showed t...
