In maize grain during cobs ripening period levels of anionic forms unsaturated fatty acids, and especially saturated fatty acids was increased. The increase of content of anionic forms of saturated, monounsaturated and polyunsaturated fatty acids under the influence of mineral nutrients, and their reduce under the influence of plant growth regulator Zeastymulin was showing. Change of the balance of anionic forms fatty acids of total lipids improves productivity of the investigated maize plants: the number cobs on the stem, their length and weight of 1000 grains of corn on the influence of mineral nutrients and Zeastymulin was increased.

Keywords: maize plants, anionic form of fatty acids of total lipids, mineral nutrients, plant growth regulator
