We have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination
This work was carried out on the natural territories in the collection and of the Yakut botanical garden (JBG). The object of study was medicinal plants used in the treatment of cardio-vascular system. On the natural territories JBG we have noted 39 species of
medicinal plants. 26 species were studied in a culture
The work was done based on the collection of the
natural flora of the Yakut Botanical Garden. The
object of research was the seeds of 22 species of the
family Ranunculaceae. It is known that the seeds of
many buttercup characterized morphophysiological
tranquility associated with hypoplasia of the fetus
(Nikolaeva, 1988; 1999), due to what delayed the
germination of their seeds. Laboratory germination of
seeds of the studied species varies from 0 to 100%.
Among them, we have not found the kinds seeds
which have explosive or fast germination (1 type of
seed germination). The germination of the studied
seeds states ranging from 6-7 days or more. The
studied seeds were evenly distributed between 2 (12
species), and 3 types of seed germination (10 species).
Type 2 is characterized by slow germination, type 3 -
poor germination or lack of it
The article presents the results of the studies on the
variability of morphological traits of the
cenopopulations of Allium prostratum, Allium
ramosum on the natural territory of the Yakutsk
Botanical Garden and in cultura. We have performed
researches of biometric parameters, which revealed the
structural features of the plant and the nature of the
variability of their parts. The article also gives an
estimation of coenopopulations vitality
The article presents the results of studies of vitality
and of the correlation variability of morphological
traits cenopopulations Lilium pensylvanicum Ker.-
Gawl. on the natural territory of the Yakutsk Botanical
Garden and in cultura. The study shows variability of
their parts (variability) and the estimation
coenopopulations vitality (vitality)
