摘要：The aim of the study was to investigate how the foliar application of iodine, as well as its concentration in the working liquid influences on the growth of fresh and dry weight of plants, stems, leaves, roots and number of shoots and leaf laminae of sand Lucerne.The experiment was carried out in vases The three plants that have developed the largest number of leaves in the vase has been left.The experimental factors as the plant growth regulator with the trade name Stymjod in three concentration 1.5%, 3% and 4,5% in the working liquid were introduced, the control has been used distilled water.Two plant applications were performed.The first one in 6 appropriate leaf phase and the second in branching formation phase.A single dose of working liquid was 50 ml per vase.This dose of liquid caused the complete sprinkling of plants in a vase.The obtained results were statistically analyzed by analysis of variance.The experiment showed that the concentration of Stymjod in the working liquid is very important.It is difficult to say which concentrations gave the best results in cultivating sand lucerne.The present studies demonstrated that Stymjod applied foliarly at 4.5% concentration significantly affected the growth of stems and leaf blades.Additionally, 1.5% concentration increased the weight of fresh matter and dry matter of roots.The experiment showed that the effects of Stymjod application to hybrid alfalfa depended on its dose.It is difficult, however, to clearly state which concentration produced the best results so further research in this area is needed.
