Fig. 5: Caryological spectrum of Calamagrostio-Salicetum cinereae association

In the case oi hedges of Calamagrostio-Salicetum cinereae the frequencies of the types of pollination and dispersal of diaspores have values comparable to those of the alder small forests of Alno-Ulmion alliance (Querco-Fagetea class). Being located in open spaces, both anemogamy and anemochory occur at high frequencies.

In all the phytocoenoses of this association, entomophilic and anemophilic species are predominant. Self-pollinated species associated with anemophilic and apogamic species appear with erratic frequencies.

Zoochory and anemochory have a predominant role in propagating diaspores. Because of high groundwater levels, mirmecochory occurs with lower frequencies, but hydrochory has higher frequencies instead (Fig. 7).
