Abstract

The study concerned shoot formation and structural and morphological peculiarities of different life forms of Nepeta pamirensis specimens, as well as their morphogenesis and its polyvariety in the conditions of the Pamir Mountains (Tajikistan). Depending on the habitat conditions, Nepeta pamirensis specimens formed three life forms: herbaceous caudex taproot perennial plants, cushion semishrubs and aeroxylic semishrubs. For each life form the phases of morphogenesis were determined and the functional and zonal structure of shoot systems were described.
