Particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined in the article. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis is analyzed
The article studies the influence of polymeric in
the form of formers and growth regulators on the
growth and development of rice plants when
grown in saline conditions. We controlled the effect
of salinity on grows regulators and vigor, seed
germination, root and shoot weight, the content of
photosynthetic pigments parameters, induction
curves of delayed fluorescence, the indicators of
structure of harvest, grain yield. It was found, that
pre-sowing seed soaking in solutions of polymer
grows regulators has a stimulating effect on the
growth and development of rice plants in the early
stages: we significantly increased germination and
emergence, dry weight of root and shoot compared
to control. At different stages of ontogeny
rice, the absolute content of pigments in the leaves
and the relationship between the individual variants
change. The absolute content of pigments in
leaves and their relationship between experiences
at different stages of ontogeny change. In the period
of intensive vegetative growth from seedling
stage the content of total chlorophyll is maximum,
and by the end of the growing season it decreases.
It can be assumed that the salinity of the substrate
significantly reduces the productivity of photosynthesis
in young plants, possibly due to imbalance
of ions in the cell, the older it gets – the weaker
the phenomenon is and even becomes reversed.
The second maximum IR ZF increases during the
growing season from germination to flowering,
then decreases to the beginning of ripening in all
embodiments. The same dynamics is characteristic
of the magnitude of the proton gradient in the
membranes of chloroplasts tylakoids. Salt protection
effect of growth regulators on grain yield is
significant on both backgrounds of mineral nutrition
