Of the bioforms spectrum (Fig. 3), one can see the predominance of the hemicryptophytes (60.53%), followed by geophytes (14.47%). The significant presence of the terophytes (10.53%) is due to anthropogenic pressures exerted on these phytocoenoses. Phanerophytes (9.21%) are also present in considerable numbers.

Fig. 3: Bioforms spectrum of Calamagrostio-Salicetum cinereae association

The chorological analysis of this association (Fig. 4) shows that Eurasian element is predominant (26.32%), followed by European element (13.16%), Circumboreal (11.84%), Eurosiberian, European-Caucasian and Paleotemperate (10.53%). Under the influence of anthropogenic factors subcosmopolite populations expanded (7.89%).

Of the total species that make up the phytocoenoses of this association, 45.45% are polyploid, 44.16% are diploid and 9.09% diploid-polyploid (Fig. 5). The diploid index has the value of 0.965.
