The features of the growth and development of Anemarrhena asphodeloides Bunge in the VILAR Botanical Garden

The results of studies in 2019-2022 of a new medicinal plant for the flora of Russia Anemarrhena asphodeloides are presented. In the conditions of the VILAR Botanical Garden, all phenological phases are observed. However, the onset of generative phases in Anemarrhena asphodeloides occurs a month later than in nature. So, flowering does not begin in June, but it occurs in the second half of July. The beginning of seed ripening is noted not in August but at the end of September. In addition, plants of Anemarrhena asphodeloides during introduction (zone of excessive moisture) reach a greater height (up to 120 cm) than in natural dry conditions (up to 100 cm). It is shown that during spring sowing, Anemarrhena asphodeloides individuals finish their vegetation in the first year of life in the rosette phase with a height of 12.8-25.7 cm (3-8 leaves). In the second year of life, the generative phase is observed in 62 % of individuals, and in the third year it occurs in 64.5 % of specimens. The average weight of air-dry rhizomes with roots is 14,9 ± 3,5 g/individuals in three-year-olds, and 18,4 ± 4,1 g/individuals in four-year-olds.
