DETERMINATION OF SOME INORGANIC ELEMENT CONCENTRATION CHANGES IN GERMINATING CHICKPEA SEEDS EXPOSED TO PROGESTERONE AND beta-ESTRADIOL BY USING WDXRF SPECTROSCOPIC TECHNIQUE

In the present study, we aimed to determine the concentration changes of some inorganic elements in germinating chickpea (Cicer arietinum cv. Aziziye-94) seeds exposed to progesterone and estradiol by using WDXRF technique. Chickpea seeds were germinated in hormone solutions of various concentrations (10(-4), 10(-6), 10(-9), 10(-12), and 10(-15) M). Essential inorganic elements, especially S, K, Cl, Mg and P, were measured in chickpea seeds after 5-days germination. Also Na and Ca, playing an important role in cells, were measured. The results demonstrated that the elements (except for Ca and Na) were augmented by all levels of both progesterone and estradiol. Compared to other concentrations, 10(-4)-10(-6)M of progesterone and 10(-9)-10(-12)M of estradiol led to higher increase in element contents. Similarly, higher root and shoot length values were recorded at these concentrations.
