STATISTICAL-ANALYSIS OF EXPERIMENTAL-DATA ON THE PRODUCTIONAL PROCESS IN RED-CLOVER

A number of morphological, physiological, and biochemical characteristics of the plants were previously investigated during ontogenesis and under conditions of varying illumination intensity and root aeration in a multifactoral laboratory experiment designed to study the effect of nitrate nitrogen on the productional process in red clover (Trifolium pratense L., cv. VIK-7, early-ripening). The experimental data in their entirety were subjected to statistical analysis, which made it possible to present them in compact form, obtain a comparative quantitative estimate of the effect of different experimental factors, clarify the most informative of the studied indices, and establish relationships among them. Ontogenesis turned out to be the leading factor, illumination intensity acted more weakly, the weakest (but reliable) action was exerted by nitrate nutrition, and the effect of root aeration was reliable in solitary cases. A structural-functional parametrization of the object of investigation and a number of relationships useful for mathematical modeling of the productional process were obtained as a result of the productional process.
