Última The effects of seasonal change of water level in an estuary on Ludwigia octovalvis (Jacq.) P. H. Raven (Onograceae) growth Acta Botanica Ribeiro,Jose Pedro Nepomuceno; Matsumoto,Reginaldo Sadao; Lima,Maria Inês Salgueiro. The Massaguaçu River estuary is an irregular estuary with sandbar breaching cycles that are irregular and happen several times each year. The species Ludwigia octovalvis is a perennial weed in several places around the world, but it is seasonal in the Massaguaçu River. In this survey we determined the relationship between the rain, estuary water level variation, and the spatial and temporal distribution of this species. In a laboratory we simulated the water level variation in water tanks in order to understand how this species responds to flooding. In the field, we determined the distribution of L. octovalvis in the higher pluviose season and in the lower pluviose season. This species is relatively common in the higher pluviose season and completely... Tipo: Info:eu-repo/semantics/article Palavras-chave: Etiolation; Estuary ecology; Stress; Submergence; Tidal.

J. Plant Physiol. Suzuki,Rogério M.; Kerbauy,Gilberto B.. This study attempted to clarify the effects of dark, light and ethylene on plant growth and endogenous levels of indole-3-acetic acid (IAA), cytokinins and abscisic acid in Catasetum fimbriatum. Dark-incubation fully inhibited root and pseudobulb formation as well as leaf growth, but favored shoot elongation. The results of continuous and active growth in dark-incubated shoots (stolons) were induced by strong apical meristem sink activity and by the significantly increased levels of cytokinins in shoots. In fact, shoot length, cytokinin and IAA levels in dark-incubated shoots were about twice as great as for those grown under light conditions. Moreover, the total cytokinin level in shoots of C. fimbriatum under light conditions without ethylene was...
