The influence of an alternating magnetic field with a different signal shape on the morphometry and ontogenesis of Zea mays L.

The paper considers the issues of factorial ecology concerning the mechanisms of influence of physical factors, in particular, an alternating magnetic field with different characteristics, on plant objects. The obtained biological effects on Zea mays L. seeds depend to a greater extent on the shape of the applied signal. It is assumed that physiological responses are associated with a change in pH, the release of proteins, and also with the barrier function of plant seed membranes. The obtained schemes for processing sugar corn with an alternating magnetic field, taking into account ontogenesis and morphometry, are further recommended to be used in the field as a method of presowing treatment of agricultural crops: B = 1 mT, f = 20 Hz, t = 60 min, sinusoid signal type; B = 1 mT, f = 50 Hz, t = 60 min, sinusoid signal type; B = 1 mT, f = 30 Hz, t = 60 min, meander signal type; B = 1 mT, f = 50 Hz, t = 60 min, meander signal type; B = 1 mT, f = 20 Hz, t = 60 min, meander signal type.
