Approbation of functional diagnostics methods for application in the plant state assessing

Abstract

The requirement of safflower (Carthamus tinctorius L., variety Alexandrite) for 14 nutrients was studied by the method of plants functional diagnostics. The possibility of using this method of plants functional diagnostics for assessing the state of plants, as well as assessing the ecological state was shown. This method is based on the chloroplasts suspension photochemical activity. It was found that the studied safflower is deficient in such mineral elements as Zn, Mg, Cu, Mo, N, KS. Doses for foliar feeding were determined based on the results of functional diagnostics. Functional diagnostic methods make it possible to assess the plant's requirement for a particular nutrient element, and not their content in the plant. The requirement of plants for elements can be estimated by controlling the intensity of physiological and biochemical processes. This method can be attributed to the main control tools in agriculture, which allows to control the crop yields. Because only with a constant supply of the necessary nutrients in optimal proportions throughout the growing season is it possible to maximize the use of the biological potential of plants. The use of plants functional diagnostic leads to a reduction in unproductive costs and the greening of agriculture. The data obtained by this method can be useful in a complex assessment of the ecological state of the environment.
