Covering Broccoli And Parsley Seeds With Biodegradable Films And Coatings [recobrimento De Sementes De Brócolos E Salsa Com Coberturas E Filmes Biodegradáveis]

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.642291297Amarante, C., Banks, N.H., Postharvest physiology and quality of coated fruits and vegetables (2001) Horticultural Reviews, 26, pp. 161-238. , LondresButler, R., Coatings, films & treatments (1993) Seed World, 10, pp. 18-24. , Des PlainesDadlani, M., Shenoy, V.V., Seshu, D.V., Seed coating to improve stand establishment in rice (1992) Seed Science & Technology, 20, pp. 307-313Dandurand, L.M., Knudsen, G.R., Influence of Pseudomonas fluorescens on hyphal growth and biocontrol activity of Trichoderma harzianum in the spermosphere of pea (1993) Phytopathology, 83 (3), pp. 265-270. , St PaulDuan, X., Burris, J.S., Seed physiology, production & technology: Film coating impairs leaching of germination inhibitors in sugar beet seed (1997) Crop Science, 37 (2), pp. 515-520. , MadisonGURNEY'S SEED & NURSERY.
