The objective of this work was to compare the performance of broccoli and parsley seeds coated or adhered to biodegradable films of gelatin and chitosan. Initially, the optimum number of coating layers and the thickness of the film were determined in order not to affect the germination of seeds. The performance was evaluated by germination capacity and vigor, and by fresh and dry weight of plants with 30 days. The seeds inserted into the films of gelatin and chitosan showed lower germination results than the control seeds. The coating of the seeds with gelatin and chitosan coatings of had good results in terms of vigor and development of plants. The results indicated that coating the seeds with biodegradable coatings can be promising due to the improvement of the germination of the coated seeds and the development of the plants when compared to the seeds with not treated.
