Abstract
Aim. The aim of the research if to study variability of the sprout of S. daghestanica, included in the list of endemic species of the Eastern Caucasus and listed in the Red Book of Dagestan.
Methods. Collection of species at the flowering stage was held in three districts of Dagestan: Gergebilskaya (751 m above sea level), Akushinsky (1058 m above sea level.) and Karabudakhkent (747 m above sea level). From each collected sample we randomly selected 30 shoots, 3 sprouts from 10 plants, morphometric features of which were taken into consideration.
Results. The group with the highest coefficient of variation of the studied traits of the S. daghestanica sprout is characterized by: "the length of the apical generative sprout", "the length of the developed lateral generative sprout", "the number of nodes on the generative part", "the number of nodes on the vegetative part" "the number of flowers on the main generative sprout", "the number of lateral generative sprouts". The variability of feature "total length of the sprout" proved to be the lowest. The relative stability of this trait, in our opinion, is due to the optimal conditions for the realization of the growth potential.
Conclusion. For such characteristics as "the number of nodes on the generative part", "the number of nodes on the vegetative part", "number of lateral generative sprouts", "the length of the developed lateral generative sprout" are under the significant influence of environmental factors. No differences could be identified or they were not valid, concerning the following characteristics: "the total length of the sprout", "the length of the generative part", "the length of the vegetative part", "the length of apical generative sprout", "the number of flowers on the apical sprout", "diameter of the vegetative part at the base", "diameter of the generative part at the base".
