In vitro propagation of avocado (Persea americana Mill.) cv. Hass through morphogenesis Acta Agron. (Palmira)
Restrepo Osorio,Catalina; Gómez Velásquez,Felipe Andrés; Gil Correal,Alejandro; Torres Bonilla,Javier Mauricio; Urrea Trujillo,Aura Inés.
Abstract Given the importance and potential development of avocado (Persea americana Mill.) cultivation in Colombia and its problems for an efficient field cultivation, which includes the genetic variability of propagated material and adverse phytosanitary conditions, the aim of this study was to develop a method for in vitro clonal propagation for avocado cv. Hass. In vitro introduction of apical explants and nodal segments was carried out from grafted parent plants. Etiolation pretreatment effect on the number of shoots formed and in vitro phenolization was evaluated in grafted parent plants and in explants under in vitro conditions, subject to photoperiod (12/12 hours) and darkness. Darkness conditions reduced significantly plant phenolization, and...

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...

Effects of light and ethylene on endogenous hormones and development of Catasetum fimbriatum (Orchidaceae) Braz. 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...
