Comparative study of morphological and physiological characteristics of the petrophytic plant Gypsophila juzepczukii Ikonn. (Caryophyllaceae)

A comparative study of the morphological and physiological characteristics of the petrophytic plant Gypsophila juzepczukii Ikonn. (family Caryophyllaceae) growing in different populations on the territory of the Zhiguli Nature Reserve in the Samara Region is presented. It was revealed that G. juzepczukii is well adapted to existence both on a rocky substrate (P-1) and on vertical rocky surfaces (P-2). At the same time, P-2 plants were noted to have a greater length and width of the leaf, the content of photosynthetic pigments, and antioxidants. Thus, in this study, variations in morphological and physiological characteristics depending on the place of plant growth were shown using two populations of G. juzepczukii as an example.
