For the conservation of biodiversity, this study of
patterns of biological processes and phases in the
development of Convallaria majalis L. that are
repeated annually becomes actual. In the article, we
have presented an analysis of five years of
observations of the rhythm of the development of
Convallaria majalis L. in the conditions of the middle
Don. There were allocated phenological phases of lily
of the valley: vegetative (beginning of sprout growth,
deploying of leaves), bud formation, flowering
(disclosure of the first flower, mass blossoming, the
withering of separate flowers, the ending of
flowering), fruitage (the beginning of fruit setting,
mass of fruit setting, mass ripening of fruits), the end
of the vegetation (appearance of the first changes in
color of leaves, the complete drying). We have defined
daily average temperature and the appropriate amount
of positive temperatures for the passage of various
phases of development Convallaria majalis L. By the
results of two growing seasons, the optimal daily
average temperature for the flowering period is 14,3 °
C (the sum of average daily temperatures 161,3-204,
0С) - until 9-15 days. At higher daily air temperatures
flowering begins at lower amount of positive and
effective temperatures after 40-45 days after the start
of the vegetation. At lower daily air temperatures
flowering is longer than at higher. In the conditions of
the middle Don there were allocated some examples of
Convallaria majalis L. which bloom two years in a
row
