The leaf morphogenesis of three meadow forb species, Convolvulus arvensis L., Prunella vulgaris L., and Phalacroloma annua (L). Dumort, was studied on the floodplain meadows of the Psyol River under pasture loads of different levels. The integrated estimation of the morphogenesis using the index of fluctuating leaf asymmetry for the investigated species is given. It is established that along the gradient of pasture digression the index of fluctuating asymmetry in Convolvulus arvensis and Prunella vulgaris increases regularly while in Phalacroloma annua the level of fluctuating asymmetry does not change. The results of the research are recommended for bimonitoring.

Keywords: meadow forbs, leaf structure, fluctuating asymmetry, pasturable digression, Convolvulus arvensis, Prunella vulgaris, Phalacroloma annua
