Abstract
The ecological, morphological, physiological and biochemical characteristics of representatives of the genus Galium (Rubiaceae) have been studied. The objects of study are the hybrid (notovid) Galium × affrenum (Klokov) Ostapko (=notovid) and its parent species G. ruthenicum Willd. and G. octonarium (Klokov) Pobed. s. l. G. × affrenum habitually is closer to G. ruthenicum, but he differs in the color of the flower. Using the method of artificial neural networks, it was shown that, according to the physiological and biochemical characteristics, the notovid is closer to the parent species G. octonarium. The leaf biomass of G. × affrenum is characterized by an increased content and greater variability in the concentration of photosynthetic pigments and lipid metabolism, which may be the key to its greater stability and viability.
