BATISTA, Juliana A. et al. Vigor of broccoli seeds submitted to biodegradable coatings and micronutrients. Hortic. Bras. [online]. 2005, vol.23, n.3, pp.841-845. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362005000300030.

The development and application of biodegradable coatings and films have been used for many years in order to improve quality of the coated or packed product. The development and characterization of pectin and pectin/gelatin-based biofilms with fatty acids was evaluated and verified their efficiency as coatings to broccoli seeds (Brassica oleracea L. var. italica). The solubility in water of the films was determined. The counting and visual observations of the germinated broccoli seeds were done each three days and fresh and dried weight of the plants were determined at the end of the experiment. Pectin-based films with stearic acid were 100% soluble in water and composite films of pectin and gelatin were 18%. The application of the biodegradable coatings on broccoli seeds had no effect on the plants development, showing their potential for commercial use. The fertilizers, sodium molibdate (0.2mg L-1) and boric acid (1mg L-1), added to the coating solution had no interference in the emergence and development of the broccoli plants.

Palavras-chave : Brassica oleracea L. var. italica; coating; biofilm; pectin; gelatin.
