The free amino acid and ammonia pools of Azolla caroliniana were analyzed by quantitative column chromatography on columns capable of separating all of the nitrogenous constituents normally found in physiological fluids. Comparisons were made of plants containing symbiotic algae and grown on nitrogen-free media, plants grown on media containing nitrate, and algae-free plants also grown on nitra...

in order to evaluate the yield and yield components of rice (oryza sativa l. cv. tarom hashemi) in integrated rice, duck and azolla, an experiment was conducted at the research farm of sari university of agricultural sciences and natural resources during 2012. experiment was arranged in split plot based on a randomized complete block design with three replications. the number of ducks as main p...

the genus azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics, and warm temperate regions of africa, asia, and america. for several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. hg, pb, cr and cd) through wastewater treatment or for elimination of...

Zinnia is an annual plant with the long flowering period from late spring to mid-autumn. It is a popular plant for landscape. In the present study, the effect of two types of growth promoting bacteria and Azolla compost on some ornamental characteristics of Zinnia were evaluated in pot cultivation and greenhouse conditions. The factorial experiment was conducted in three replications based on a...

This study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by Azolla caroliniana.  The experimental investigations have been carried out using Azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). Th...

Sustainable agriculture demands reduced input of man-made nitrogen (N) fertilizer, yet N2 fixation limits the productivity of crops with heterotrophic diazotrophic bacterial symbionts. We investigated floating ferns from the genus Azolla that host phototrophic diazotrophic Nostoc azollae in leaf pockets and belong to the fastest growing plants. Experimental production reported here demonstrated...
