Development dynamics of some carnations (Caryophyllaceae) met in the north-east part of the Small Caucasus

Summary

The article presents the phytocenological features of some carnations (Stellaria persica, Myosoton aquaticum, Cerastium davuricum, Cerastium cerastoides) distributed in Shamkir, Gadabay and Dashkesan regions. The species of Cerastium davuricum was studied in the composition of meadow clover-fescue (Trifolieta– Festucosum) formation, Cerastium cerastoide in the plant cover with association of multibranched Tamarisk hohenackeri (Tamarixetum ramasissima –T. hohenackeri). Phytocoenotic growth dynamics of Stellaria persica and Myosoton aquaticum at the coenopopulation level were studied in the hairy feather grassmeadow grass (Stipaetum capillata–Poaosum pratensis) association in Dashkasen district. In 2019, the coenopopulation was normal, full, with a density index of 69. The age spectrum was maximal in juvenile and virginile individuals. According to the “Delta-Omega” classification, individuals are young. In 2020, the coenopopulation began to rejuvenate. However, the dynamics of the age spectrum of only Stellaria persica was low. All changes that occur are fluctuation changes. The age spectrum characteristic of this species was preserved, and its viability was high.
