Взаимодействие с микоризными грибами — ведущий фактор морфогенеза корней двудольных в умеренных эдафических условиях?

Abstract

The features of root systems and root structure of 28 herbaceous dicotyledon species (fam. Apiaceae, Asteraceae, Caryophyllaceae, Lamiaceae and Polygonaceae) in relation to their potential and actual mycorrhizal status, biomorphes and duration of ontogenesis were investigated. It is shown that the key bioecological characteristics that best explains the features of roots structure is actual mycorrhizal status, i.e. presence or absence of mycorrhiza in the species in a particular study. Ontogenesis characteristics (annual or perennial species) and biomorphological structure (with tap or rhizome) have less explanatory value in relation to the structure signs of roots of herbaceous dicots.
