Duckweed consists of four genera: Lemna, Spirodela, Wolffia and Wolffiella. So far, 37 species belonging to the four genera have been identified from different parts of the world. Selected species are listed in Table 3.1. Taxonomically the family is complicated by clonal characteristics (Culley et al., 1981). The most commonly
21 Dec 2017 Full-text (PDF) | Duckweeds have been consumed as human food since long. Species of the duckweed genera, Spirodela, Landoltia, Lemna, Wolffiella and Wolffia were analysed for protein, fat, and starch contents as well as their amino acid and fatty acid distribution. Protein content spanned from 20%
Duckweed. Family Lemnaceae. Duckweeds are very common in Iowa waters. These aquatic plants are the world's smallest and simplest flowering plants. Duckweeds are floating plants that grow on the surface of still or slow moving waters during warmer weather. Because duckweeds usually reproduce by budding, they.
30 Mar 2016 Full-text (PDF) | Lemnaceae, or duckweed as it is commonly called, is a well-known organism that is ideal for biological experiments due to its easy maintenance, rapid reproduction rate and abundance (Kuhn, D., 1969). The four genera of duckweed are Lemna, Spirodela, Wolffia and Wolfiella ( Riemer

Duckweeds are plants on a miniature scale; they have leaves, roots and flowers – just very small ones! Duckweeds float on the surface of ponds. Where there is a lot of duckweed it can block out sunlight, which affects other pond life. This chart shows six duckweeds that you might see when you're spending time around the

Duckweed species can grow so densely on water surfaces that they appear as finely groomed turf. They are considered the world's smallest flowering plants. To put their size and numbers in perspective, watermeal is approximately the size of a sugar crystal or a grain of salt, which translates to 5 to 10 billion plants per acre.
ABSTRACT. The minute, reduced plants of family Lemnaceae have presented a formidable challenge to systematic inves- tigations. The simplified morphology of duckweeds has made it particularly difficult to reconcile their interspecific relation- ships. A comprehensive phylogenetic analysis of all currently recognized
Results 73 - 84 Abstract: Duckweed (Lemna minor L.) has a wide application in Turkey having suitable climatic conditions. In this study, the growth of duckweed was assessed in laboratory scale experiments. They were fed with municipal and industrial wastewater at constant temprature. COD, total nitrogen. (TN), total
