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
The article investigates the impact of waste of elevators on morphological parameters and productivity of winter wheat grown on black leached soil
The article studies the impact of different substrats on rizoplane microflora of pelargonium zonale in protected ground
The article is devoted to the investigation of the influence of applying elevators waste to the soil on the content of ions Ca2+, K+, NH4+ , NO3 - and photosynthetic pigments in leaves of plants of winter wheat in the cultivation of the leached black soil
The article studies the impact of waste and ash from the elevators of their burning on the microflora of rhizoplane, rhizosphere and phylloplane of winter wheat grown on leached black soil
The article is devoted to the law and technological problems of elevators waste products processing into soil.
In the course of research the impact of polymeric pellicle-forming growth regulators (PGR) on the growth and development of rice plants while cultivated in conditions of salinity has been studied. It was ascertained that preseeding PGR treatment of seeds at the rate of 10 liters of solution for 1 (one) ton of seeds boosts germination energy, germinating ability of seeds, sprouts, length gets extended and weight enlarged. PGR lead to increase of electrochemical gradient on the membranes of chloroplasts, tilacoids and acceleration of electrons transport between I and II photo systems. PGR diminish toxicity of salinity which is fixed in parameters measured in experiments that are close to the control values. PGR application improves parameters of the structure of rice crop cultivated in conditions of salinity.
