Abstract:

This paper presents the influence of some fertilizers with microelements such as metal-ammonium phosphates on germination of Triticum aestivum seeds. The study presents experimental results regarding the effect of the solutions of different concentrations of copper-ammonium phosphate, iron (II)-ammonium phosphate, and zinc-ammonium phosphate on germination of Triticum aestivum seeds. Experiment aims to further the process of germination and development of caryopses, at histology level.To obtain chemical fertilizers with microelements such as metal-ammonium phosphates were used waste solutions from galvanic industry, diammonium phosphate and ammonia solution 25% [1,2]. Solutions were prepared on concentrations 0.1, 0.05, 0.025 and 0.0125% of each metal-ammonium phosphate. Lots of 30 seeds of Triticum aestivum L. were set for germination in Petri plates on filter paper, soaked with common water boiled and cooled. Seeds were kept in the dark 12 h at temperature 20-240C, during which germinates and the length of the rootlets is maximum 1-2 mm. After 12 h of germination, water is removed, the seeds are put in contact with the treating solutions, with the concentrations ranging from 0.1 to 0.125%. 24 h after the treatment of the seeds, there was read the length of the rootlets and calculated the inhibition coefficient and also it was determined the influence on mitotic cell division by microscopic examination [3]. Keywords: fertilizers with microelements, metal-ammonium phosphates, inhibition coefficient
