Properties of сrezacin as a growth stimulant of vegetable amaranth (Amaranthus L.)

Сrezacin, tris(2-oxyethyl)ammonium ortho-cresoxy acetate-based adaptogen of humans and animals, is applied in Russia as a stimulant of growth and productivity of crops (wheat, oats, spinach, potatoes, etc.). In other countries, crezacin is not used for these purposes. There is no information about its use in the cultivation of food amaranth ( Amaranthus L.), a source of high-quality protein and other useful substances. In this paper, we first report data on the effect of pre-sowing treatment with crezacin on seed germination, development and biometric parameters of amaranth plants during ontogenesis, and on their productivity and nutritive value. Our findings indicate the ability of crezacin to increase nitrate reductase activity, to influence the nitrite nitrogen content in the early stages of vegetation, to increase the electron transport rate ATP synthesis. The aim of the work was to assess the effect of different crezacin concentrations on seed germination, seedling quality, growth parameters, and activity of photosynthesis and nitrogen assimilation apparatus...
