TESTING THE INFLUENCE OF THE ENVIRONMENTALLY FRIENDLY PHYTOHORMONE GIBB A3, UPON MAIZE MACROAND MICROELEMENTAL CONTENT

摘要

Ourdays, the identification of friendly solutions in order to enhance physiological development of cereals is one of themain priorities of agriculture. This approach, also contributes to the promotion of the practices of the sustainableagriculture. A practice, which occupies more and more space is the use of endogenous type substances, asphytohormones, in order to increase cereals’ physiological development, and nutritional traits. This is the contextwhere the aim of our study is placed, meaning that we focused on determining the effects of GIBB A3 phytohormone ontwo maize hybrids content in macro-, and microelements, within specific environmental conditions of Transylvania.Two maize hybrids were studied, Turda Star, and Turda 200, respectively, and their elemental content was quantifiedby AAS, and raw data were processed with IBM SPSS Version 20. The results of our trial show the influence of GIBBA3 hormone upon the analyzed macro- (K, P, S, Cl, Mg, Ca), and microelemental (Fe, Mn, Zn) content of studied maizehybrids, mainly K, and P, which may also be considered as indicators of physiological status of the plant.
