The main goal of the present study was to establish the effect of ultrasound on the sowing parameters of snapdragon (Antirrhinum majus L.) seeds. Experiments were carried out with three varieties snapdragon. The seeds were sonicated with ultrasound for 2, 4, 6 and 8 minutes. The following parameters were investigated: germination energy, germinability, Mean germination time, Uniformity of germination, length of embryo root and hypocotyls, and fresh weight of the sprouts. The sowing parameters were improved from each duration of ultrasound treatment. The best results for germination and in most of the parameters were found about treatment with 6 minutes. The high correlation between the length of hypocotyls and embryo root and fresh weight was established. Polynomial regression with a high determination coefficient was registered.
