Accumulation of starch in duckweeds (Lemnaceae), potential energy plants
Physiology and Molecular Biology of Plants, 2021Starch can accumulate in both actively growing vegetative fronds and over-wintering propagules, or turions of duckweeds, small floating aquatic plants belonging to the family of the Lemnaceae. The starch synthesizing potential of 36 duckweed species varies enormously, and the starch contents actually occurring in the duckweed tissues are determined by ...

Uptake and partitioning of zinc in Lemnaceae
Ecotoxicology, 2011Macrophytes provide food and shelter for aquatic invertebrates and fish, while also acting as reservoirs for nutrients and trace elements. Zinc accumulation has been reported for various Lemnaceae species. However, comparative accumulation across species and the link between zinc accumulation and toxicity are poorly understood.

Summary Lemna minor L. and Wolffia brasiliensis Weddell can use sucrose to support heterotrophic growth in darkness and photomixotrophic growth in the light, but each is killed by galactose in the medium. Spirodela punctata (G. F. W. Meyer) Thompson growth on sucrose and galactose was indistinguishable. L.

Flower development inSpirodela polyrrhiza (Lemnaceae)
Plant Systematics and Evolution, 1979Flowering under experimental conditions inSpirodela polyrrhiza, and the development of the spatha, stamina and pistil are described and illustrated by microphotographs. During the development of the microsporangia the existence of the middle layer between endothecium and tapetum has been documented for the first time inLemnaceae.

Allozyme divergence among species ofWolffia (Lemnaceae)
Plant Systematics and Evolution, 1995The genusWolffia was surveyed electrophoretically at 14 allozyme loci. A total of 133 clones representing 10 of the 11 recognized species was examined. Genetic identities among most pairs of species are zero, with non-zero values ranging from 0.14 to 0.40.Wolffia angusta and the newly describedW.

Ethylene Production and Overcrowding in Lemnaceae
Journal of Plant Physiology, 1986Summary In the present paper the effect of pushing together duckweeds on their ethylene evolution is communicated. The production of Lemna gibba G1 and Lemna aequinoctialis 6746 in a loose state was low and constant, ranging between 0.25 and 0.5 nl/g FW/h. After crowding, ethylene evolution increased slowly in L.

DIFFERENTIAL SENSITIVITY OF DUCKWEEDS (LEMNACEAE) TO SULPHITE
New Phytologist, 1986SummaryFrond replication and some aspects of carbon assimilation were observed in three species of duckweed (Lemnaceae) grown at two levels of irradiance in the presence and absence of sulphite. The objectives were to examine the relationship between the inhibition of frond replication caused by sulphite, and changes in carbon assimilation, and the ...

American Midland Naturalist, 1937
The Lemnaceae represent a group of floating aquatic plants of considerable economic and biological importance and of unique botanical interest. Of about 26 species known in the world, 13 are known from the United States and 10 from Indiana. The family includes the smallest flowering vascular plants in the world and the flowers themselves are among the ...
