Abstract

Irina Krohmal, Maxim Netsvetov

Morphological and anatomical treats of Campanula trachelium L. leaves from 8 samples of different sites of seed origin have been studied. There were described labile and stable leaf treats of plants growing in the steppe zone of Ukraine. The labile treats, i.e. petiole length and its ratio to width of leaf blade, number of trichomes and stomata on adaxial leaf side, are not strongly relate with climatic conditions in seed origin sites. The stable treats, i.e. leaf blade size, thickness of epidermis and palisade mesophyll, relate with climatic parameters in sites of origin.
