On the basis of the concepts of I.G. Serebryakov (founder of the science of plant life forms, ecological morphology) and an analysis of current data, the main directions of research and achievements...

The development of Scutellaria supina individuals has been studied in the Asian part of its distribution range. Four life forms (subshrub, dwarf subshrub, taproot herbaceous polycarpic, and long-rhizo

The morphogenesis and structural and morphological polyvariation of monocarpic shoots of individuals of Panzerina species, growing in different ecological and phytocoenotic conditions in Siberia, were studied. Depending on the habitat conditions, adult plants of P. lanata subsp. argyracea form three ontobiomorphs; P. canescence plants form two ontobiomorphs; and P. lanata plants form a single one. It was determined that Panzerina species ontomorphogenesis can be realized through three main variants, including a total of 26 possible ways.

This paper presents the results of a study of the ontogenesis and structural and morphological features of various life forms of Nepeta pulchella Pojark. (Lamiaceae). The environmental and coenotic fe

The paper presents the results of the complex study of main biological and chemical characteristics in the endemic species Nepeta densiflora which occupies the boundary position in the distribution of Spicatae (Benth.) Pojark.section of Nepeta genus. It has been established that the ontogenesis is complete and the individuals successively pass the morphogenesis stages: primary shoot → primary bush → clump → branching particle. Assessment of coenopopulation states has identified the studied population as normal and stable. Coenopopulation stability is determined by its seed regeneration and complex ontogenesis. Species existence under the studied ecological and coenotic conditions can be successful, provided that there is no phytocoenotic environment composed of turfed lady’s mantle community. In N. densiflora, the main components of the essential oil were found to be cis-trans-Nepetalactone (up to 70%), cis-β-Ocimene (4.8%), Germacrene D (3.1%) and β-Cyclocitral (2.4%).
