INFLUENCE OF LOW-INTENSITY ELECTROMAGNETIC RADIATION OF THE MILLIMETER RANGE ON THE PIGMENTAL COMPOSITION AND PHOTOSYNTHETIC ACTIVITY OF <i>TRITICUM AESTIVUM</i> L. UNDER CHLORIDE SALINATION
This work shows the adaptive effects of Siliplant on Triticum aestivum L. under water-scarce conditions. The results of the study showed that Silisplant has a stimulating effect on the vigour of the sprouting and sprouts wheat seeds when treated with different concentrations of the drug. Pre-sowing soaking of Bunchuk wheat at at various concentrations of the synthetic Silisplant growth regulator has been shown to have a stimulating effect on the build-up of dry matter from above-ground plants in the early stages of ontogenesis. The optimum time for seed soaking, in which the experimental variants exceed the control variants maximum, is 240 mines. The positive influence of the growth regulator Silisplant on germination and growth processes Triticum aestivum L., variety Bunchuk both under optimal conditions and under conditions of water scarcity has been established. The optimum concentration of the synthetic growth regulator is shown to be 0.3 %. In 4-day experimental sprouts, the seeds of which were pre-treated for 240 minutes in a solution of a drug of a given concentration, the mass of the raw material increases on average by 50 %, The dry matter mass is 33 %, the length of the coleooptyl is 34 %, and the length of the root system is 44 % compared to the control under conditions of water scarcity. The positive influence of synthetic growth regulator Silisplant on morphometric indicators Triticum aestivum L., variety Bunchuk has been established. The runoff height increases reliably by 22 %, the root length by 23 %, the raw material mass by 9-13 %, and the dry matter weight by 14-25 % in experimental plants compared to control plants under conditions of insufficient water supply. Triticum aestivum L., The optimum concentration growth regulator increases transpiration intensity by an average of 43 % and reduces water scarcity by 56 % in experimental plants compared to control plants under conditions of water scarcity. Thus, the stimulating influence of growth regulator Siliplat on vigour of germination, laboratory germination, length of above ground part, length of root system, indicators of water balance of plants Triticum aestivum L., variety Bunchuk with insufficient water supply is shown.
