Analysis of the calendar age of (Pyrola rotundifolia L.) ramets at interpretation of ontogenetic structure species

The ontogenetic structure of pricing of Pyrola rotundifolia had been studied. It is shown that a high proportion of plants of the virginal ontogenetic state in the structure of the coenopopulation can be caused both by delayed development of plants and by intensive vegetative propagation processes, during which a systematic replenishment of the cenopopulation with young ramets is noted. The chronological age of plants can be used to correctly interpret the ontogenetic structure of the coenopopulation. An increase in the chronological age, accompanied by a gradual transition of plants to a more adult ontogenetic state, may indicate normal plant development. The increase in the length of the stay of the ramet in the virginal ontogenetic state, the correspondence of the chronological age of the plants of the virgin and mid-generation generative state is associated with difficulties in the transition of plants to flowering.
