The main aim of the present study was to investigate the possibility of the application of ultrasound for stimulating the viability behaviors of gladiolus seeds. The studies were carried out with seeds of three varieties of gladiolus. Seeds were treated with ultrasound for 2, 4, 6, and 8 min. Germination energy, germination, main germination time, uniformity of germination, time of 50% germinated seeds, seedling morphology- length of embryo root, length of hypocotyls and fresh weight were reported. The correlation dependences on the seedling's weight with the length of embryo root and hypocotyls, as well as a linear polynomial regression between the treatment period and germination, characterized with high determination coefficients were established. The highest viability was reported in the treatment of 6 minutes of ultrasound, approximately 20% above the control. These results can be used in hybridization breeding to accelerate seed development in the propagation of corms.
