	Population Growth of Lemna and Azolla
		The objective of this experiment was to analysis the growth of a Lemna population.
		Consequently, Lemna will grow as long as it will be limited by the availability of resources or by the competition with other individuals of its own species.
		Probably, because Lemna generations overlap in many populations, Lemna should have a growth rate superior to most of the other organisms that are submitted to important environmental resistance (death).

	The Lemnaceae (Duckweed Family)
		In Spirodela, Landoltia and Lemna it is a flattened structure with slender, hairlike roots on the underside.
		The plant bodies (fronds) of Lemna valdiviana are often connected in clusters of four to seven, and the nerve ("vein") typically extends 3/4 of the distance from the node (point of root attachment) to the apex.
		Lemna aequinoctialis is clearly a short-day plant because it requires 16 hours of darkness (8 hours of light) to flower.

	Lemna - Wikipedia, the free encyclopedia
		Lemna is a genus of free-floating aquatic plants from the duckweed family.
		The duckweeds have been classified as a separate family, the Lemnaceae, but some researchers (the AGP II) consider the duckweeds members of the Araceae.
		Lemna species grow as simple free-floating thalli on or just beneath the water surface.

		Lemna had been in trouble up and down the California coast the past few years for drugs, assault and "pimping" girls.
		The officer asked Lemna for "a paper." Lemna took Officer Gobert into Payne's restaurant, and fished what he claimed was heroin from behind a vending machine and sold it to the officer for six dollars.

	Comparative Sensitivity of Selenastrum capricornutum and Lemna minor to Sixteen Herbicides.
		The investigators compared the relative sensitivity of the algae Selenastrum capricornutum and the floating vascular plant Lemna minor to 16 herbicides(atrazine, metribuzin, simazine, cyanazine, alachlor, metolachlor, chlorsulfuron, metsulfuron, triallate, EPTC, trifluralin, diquat, paraquat, cicamba, bromoxynil, and 2,4-D).
		Lemna was tested according to the 96 hour assay of Taraldson and Norberg-King (1990), which was basically modified from APHA (1985) by eliminating EDTA and including a soil extract as an additional nutrient source.
		Entity - Selenastrum capricornutum and Lemna minor; Associated attributes - Aquatic Plant Toxicity and Sensitivity to 16 herbicices: alachlor, atrazine, bromoxynil, chlorsulfuron, cyanazine, dicamba, diquat, EPTC, metolachlor, metribuzin, metsulfuron, paraquat, simazine, triallate, trifluralin, 2,4-D as measured by EC50, NOEC and LOEC.

		The genus Lemna, that belongs to the Duckweed family, is found throughout all parts of the world.
		The species in the genus Lemna are, as the other genera in the Duckweed-family (Lemnaceae), greatly reduced plants, that neither have real leaves nor stem, but the whole plant consists only of a flat body, and as a characteristic for the genus Lemna a single root.
		In the genus Lemna there are 14 described species, of these, three are living in the nature in northern Europe.

	Nitrate and Lemna
		Algae have a daily cell number doublng, at the very least, whilst Lemna a 2.4 day doubling at most.
		Lemna therefore loses out and the pot grows green with algae.
		The answer to this is as for any other plant (makes proteins) also high nitrate and low oxygen in the water with added decay bacteria induces dentrification.

	Blue Light-induced Chloroplast Reorientations in Lemna trisulca L. (Duckweed) are Controlled by Two Separable Cellular ... (Site not responding. Last check: 2007-10-10)
		In Lemna trisulca and other higher plant species characterized so far, orientational movements of chloroplasts are induced by blue light, and their action spectra suggest a common photoreceptor (flavoprotein), involved in both LFR and HFR induction (6).
		This theoretical study indicated that LFR and HFR in Lemna are controlled by two different rate-limiting processes and consequently may involve separate regulatory mechanisms (10).
		Further studies with the use of several calcium antagonists have indicated that although the proper regulation of cytosolic calcium homeostasis is indispensable for both LFR and HFR in Lemna, some additional, as yet undefined, factors are required to specify the direction of chloroplast movement (14).

	Modeling duckweed growth in wastewater treatment systems
		A model or mathematical expression derived from duckweed growth data was used to fit data from experiments conducted in a greenhouse in Lubbock, Texas.
		The data used in the above analyses were based on Lemna biomass harvested from the first trough in each series (A, E, I and M Figure 1) that received the wastewater at one of these six concentrations (0, 3.9, 8.9, 13.9, 28.5 and 54.6 mg/litre TN).
		The main objective of developing this model was to separate the effects of N, temperature, and solar radiation on the growth and protein content of duckweed.
