Morphophysiological reactions of Amaranthus retroflexus L. plant depending on the place of growing
Summary
The accumulation of dry biomass and forms of nitrogen in the root and above-ground organs of wild-growing amaranth (Amaranthus retroflexus L.) was studied. Plant samples were taken from the Kurdamir (experimental plot), Barda and Tartar regions of Azerbaijan. It was shown that the accumulation of dry biomass in the roots decreased by 86% in Barda, and by 70% in the Tartar region, and in aboveground organs it decreased by 85% and 52%, respectively, relative to the control. The analysis of the obtained data on the distribution of protein nitrogen showed that its content in the root and aboveground organs of plants, in the Tartar and Barda regions decreased compared to the samples taken from the Kurdamir region. At the same time, it should be noted that the content of protein nitrogen in the Barda region was higher than in plants taken from the Tartar region. It is believed that an increase in the amount of protein nitrogen in the roots can be an indicator of plant survival as an integral part of the mechanism of adaptation to adverse environmental conditions.
