Thus, there is a lack for studies that discuss the theme about production practices of the mangrove ecosystem species seedlings. This study had the objective of: describe the phonological pattern of three typical species of mangrove ecosystem in order to provide information about the collection times and know the degree of correlation with environmental variables with the phonological periodsassess thein fluence of saline fertilization with NaCl and KCl on the production of seedlings of different mangrove species. This study showed that the environmental variables related of temperature were the most influential factors on phenology of Laguncularia racemosa, while the fluctuation of the water level acted strongly on the phenology of R. mangle. For Avicennia schaueriana the Salinity was the highest correlation with phenological events. The results showed that for L. racemosa species fertilization with NaCl at a concentration of 2 grams per liter of water gave larger increments to the seedlings. For R. mangle is recommended that 16 g of NaCl per liter of water, 10 ml of this solution applied weekly. / Uma das principais medidas de recupera??o ambiental de um ecossistema ? o restabelecimento de sua vegeta??o, que pode ocorrer por meio da produ??o de mudas de esp?cies nativas e posterior plantio, embora em se tratando dos Manguezais, o tema ? pouco debatido. Dessa forma, h? a necessidade de estudos que abordem o tema e discutam as pr?ticas de produ??o de mudas de esp?cies do ecossistema Manguezal. Assim, este trabalho teve como objetivos: descrever o padr?o fenol?gico de tr?s esp?cies t?picas do ecossistema Manguezal, no intuito de fornecer informa??es acerca das ?pocas de coleta e conhecer o grau de correla??o com as vari?veis ambientais com os per?odos fenol?gicos; avaliar a influ?ncia da aduba??o salina com NaCl e KCl sobre a produ??o de mudas de diferentes esp?cies de mangue. Este estudo comprovou que a as vari?veis ambientais ligadas ? temperatura foram os fatores de maior influ?ncia sobre os eventos fenol?gicos de Laguncularia racemosa, enquanto que a flutua??o do n?vel da mar? atuou fortemente sobre a fenologia de Rhizophora mangle. Para Avicennia schaueriana a salinidade foi a de maior correla??o com os eventos fenol?gicos. A an?lise dos resultados mostrou que para a esp?cie L. racemosa a aduba??o com NaCl a uma concentra??o de 2 gramas por litro de ?gua proporcionou maiores incrementos ?s mudas. J? para R. mangle ? recomendada a de 16 g de NaCl por litro de ?gua, aplicados 10 ml desta solu??o semanalmente.
