Abstract

ABSTRACT: Understanding germination is extremely important for the production of seedlings that are used in revegetation of degraded areas. Some species enter dormancy as a survival strategy to overcome adverse environmental conditions. Their seeds germinate only when this process is interrupted, which can occur naturally when the conditions become more favorable for the survival of the species or by induction. Studies showed that ultrasound can increase the germination rate of seeds. The objective of this research was to evaluate the effect of an ultrasound probe and compare it with other methodologies implemented for seed germination of Senna multijuga (Rich.) H. S. Irwin & Barneby, a species used in revegetation of degraded areas. The experiment evaluated the effect of the ultrasonic probe at different powers on seeds that were placed to germinate in a gerbox on paper moistened with distilled water. Ninety-five percent of seeds treated with ultrasound and only 14% of non-treated seeds (control) germinated. There was no significant difference in the germination among the treatments with different powers. The speed of germination index (SGI) reached 4.7 in seeds that underwent the treatment, and 0.6 in the control group. From the results it is possible to conclude that the ultrasound probe is an efficient treatment to accelerate seed germination in this species; and consequently, contributed to production of a greater number of seedlings to be used in revegetation of degraded areas in a short period of time.
