Performance of Azolla caroliniana Willd. and Salvinia auriculata Aubl. on fish farming effluent.
The increasing release of untreated fish farming effluents into water courses that flow to the Pantanal wetlands in Mato Grosso (Brazil) may drive this ecosystem to eutrophication. Therefore, the growth of Azolla caroliniana Willd. and Salvinia auriculata Aubl. in fish farming effluent and their effect on its quality were evaluated for 48 days in a greenhouse. The results were compared to those...
متن کاملCompetition between Salvinia minima and Spirodela polyrhiza mediated by nutrient levels and herbivory
We investigated the effects of initial biomass, nutrients, herbivory, and competition with Spirodela polyrhiza (L.) Schleid on Salviniaminima Baker biomass and density. S. minima populationswere subjected to two levels of herbivory (control vs. two adults per plant) from the weevil Cyrtobagous salviniae Calder and Sands and eight levels of competition from S. polyrhiza, while growing in high (5...
متن کاملBiochemical responses and accumulation of cadmium in Spirodela polyrhiza.
The present study focused on biochemical responses of Spirodela polyrhiza to cadmium stresses and its accumulation. The laboratory experiments were conducted for the assessment of biochemical responses and accumulation of cadmium in plants at its various concentrations (0.1, 0.5, 1.5 and 2.0 ppm) at the regular interval for twelve days exposure. Spirodela showed visible symptoms like withering ...
متن کاملThe Spirodela polyrhiza genome reveals insights into its neotenous reduction fast growth and aquatic lifestyle
The subfamily of the Lemnoideae belongs to a different order than other monocotyledonous species that have been sequenced and comprises aquatic plants that grow rapidly on the water surface. Here we select Spirodela polyrhiza for whole-genome sequencing. We show that Spirodela has a genome with no signs of recent retrotranspositions but signatures of two ancient whole-genome duplications, possi...
متن کاملThe Mitochondrial Genome of an Aquatic Plant, Spirodela polyrhiza
BACKGROUND Spirodela polyrhiza is a species of the order Alismatales, which represent the basal lineage of monocots with more ancestral features than the Poales. Its complete sequence of the mitochondrial (mt) genome could provide clues for the understanding of the evolution of mt genomes in plant. METHODS Spirodela polyrhiza mt genome was sequenced from total genomic DNA without physical sep...
