Duckweed: Growth factor and applications in nonfood, food, and health
Versatile Duckweed! Duckweeds are aquatic plants that are mainly constituted of five genera, Lemna, Spirodela, Wolffia, Wolffiella, and Landoltia. The growth rates and chemical compositions are influenced by light intensity, photoperiod, nutrient content, microbial growth, temperature, medium salinity and conductivity, windspeed, climate, and water pH.

Modification of chromate toxicity by sulphate in duckweeds (Lemnaceae)
Two duckweed species, Spirodela polyrhiza and Lemna minor, were used to measure the toxicity of chromate (100 microM) at three levels of sulphate (13 microM, low sulphate=LS; 410 microM, normal sulphate=NS; 10,000 microM, high sulphate=HS). Growth rates calculated on the basis of dry weight, chlorophyll and carotenoid content were all reduced by ...

A substantial number of Lemnaceae are invasive outside their natural distribution area. Lemna minuta is considered invasive in several European countries, where it can occur in the same habitat as invasive Azolla filiculoides and native Lemna minor.

Native Growth and Conservation of Duckweed (Lemnaceae) in Jordan
Duckweeds are the world's smallest flowering plants. Its existence is affected by the water quality and availability. The increased water demand and water scarcity in most of the Mediterranean countries as Jordan have caused remarkable lowering in the water-table which reduced floods and disappearance of the seasonal lakes.

ilustraciones, fotografías, mapas Las Lemnaceae son una familia de plantas acuáticas errantes caracterizadas por la reducción de sus órganos y la poca diferenciación morfológica. La familia consta de cinco géneros y 37 especies y presenta una distribución casi cosmopolita. En Colombia se presentan los cinco géneros (Landoltia, Lemna, Spirodela, Wolffia,
