A novel bioassay using root re-growth in Lemna.
A new phytotoxicity test method based on root elongation of three Lemna species (Lemna gibba, L. minor, and L. paucicostata) has been developed. Tests with aquatic plants have, typically, favored measurements on fronds (e.g. frond number, area, biomass) rather than on roots, due, in part, to issues associated with handling fragile roots and the time-consuming procedures of selecting roots with ...

متن کاملEvaluation of Blue Tilapia (Oreochromis aureus) for Duckweed (Lemna minor) Control in South Carolina's Private Waters
We evaluated the consumption of duckweed (Lemna minor, Linnaeus) by juvenile Blue Tilapia (Oreochromis aureus, Steindachner) through 48 hour indoor tank feeding trials. Feeding trials consisted of 5 tanks (4 treatment, 1 control). Tanks were stocked with 25 g of fresh duckweed at the initiation of each feeding trial. Designated treatment tanks were also stocked with 1 tilapia per tank. At the e...
متن کاملEvaluation of environmental bacterial communities as a factor affecting the growth of duckweed Lemna minor
BACKGROUND Duckweed (family Lemnaceae) has recently been recognized as an ideal biomass feedstock for biofuel production due to its rapid growth and high starch content, which inspired interest in improving their productivity. Since microbes that co-exist with plants are known to have significant effects on their growth according to the previous studies for terrestrial plants, this study has at...
متن کاملPhytoremediation of Cu, Cr and Pb mixtures by Lemna minor.
The present study reports the capacity of the aquatic macrophyte Lemna minor to remediate combinations of Cu(II), Pb(II) and Cr(III) from a simulated natural environment. The effect of these metal mixtures on the growth of L. minor was also investigated using growth rate and biomass inhibition calculations. L. minor was successful in removing Cr and Pb from the water, and it remained an effecti...
