| description | Background. Symphytum officinale L. is a valuable forage and medicinal plant.
The roots and leaves of the species are used in folk medicine as an antimicrobial and antiinflammatory
agent; preparations from the roots of the plant have pronounced immunostimulating
properties. The basis of introduction is the passage of the species through
all stages of the life cycle in the conditions of culture, the ability to form fruits and seeds.
Materials and methods. Ontogenetic studies were carried out according to the methodology
of T.A. Rabinova, with additions by A.A. Uranov and E.L. Nukhimovsky. Results. S. officinale
in the conditions of the Angara region there are 3 periods of ontogenesis: latent, virginal,
generative. Seedlings appear on the 14th-15th day. A rosette of leaves begins to form
in juvenile plants. In immature individuals, branching of shoots begins, while the number of
leaves in the rosette increases by 2 times. Young generative individuals bloom for the first
time for 1-2 years of life. Individuals enter the middle-aged generative state for 3 years, two
generations of shoots are observed in plants. At the 4th year of life, the plants pass into the
old generative state. At the end of August-September, individuals have a partial rhizome.
The following year, a large number of new reproductive shoots begin to grow from the renewal
buds on the rhizome. Conclusions. In the conditions of the Angara culture, S. officinale
successfully passes all stages of development, blooms, forms fruits and seeds. The
plant is a promising species for cultivation in the conditions of culture of the Angara region.
It has a number of advantages for feed production: with rapid growth and development,
during the growing season, the species has two generations of shoots, the plant has good
otavnost and the ability to form a large number of adventitious buds and shoots, the absence
of characteristic signs of rapid biological aging, self-rejuvenation, vegetative and seed reproduction,
high productivity of stems, leaves and roots. |
