Uptake and transformation of phenols by duckweed (Lemna gibba)
Phenol and its derivatives are common constituents of numerous natural and synthetic chemicals including pesticides. As a consequence of anthropological activities, a portion of them may reach various water bodies as contaminants which will have a great impact on the aquatic environment including biota. Aquatic plants are known to be one of the major habitants and food for many species and henc...
متن کاملAdjuvants Affect Duckweed (Lemna minor) Control with Pelargonic Acid
Duckweeds (Lemna spp.) are small, free floating aquatic plants that flourish on stagnant or slow moving water surfaces throughout the world. Members of the genus are among the smallest flowering plants, providing food for fish and fowl, but their aggressive growth and invasive tendencies make them formidable aquatic weeds, which when uncontrolled can result in oxygen depletion, fish kills, and ...
متن کاملPb-Induced Avoidance-Like Chloroplast Movements in Fronds of Lemna trisulca L.
Lead ions are particularly dangerous to the photosynthetic apparatus, but little is known about the effects of trace metals, including Pb, on regulation of chloroplast redistribution. In this study a new effect of lead on chloroplast distribution patterns and movements was demonstrated in mesophyll cells of a small-sized aquatic angiosperm Lemna trisulca L. (star duckweed). An analysis of confo...
متن کاملRole of Catecholamines in Promotion of Flowering in a Short-Day Duckweed, Lemna paucicostata 6746.
l-Epinephrine, l-norepinephrine, and l-isoproterenol substantially promote flowering under a photoperiodic regime of 8 hours light and 16 hours darkness in Lemna paucicostata 6746 when grown on the modified Bonner-Devirian medium devoid of ethylenediaminetetraacetic acid. If catecholamines are provided to plants at 10(-4) molar level prior to transferring them to the short-day regime, they not ...
متن کاملEffect of copper on the toxicity and genotoxicity of cadmium in duckweed (lemna minor L.).
We investigated interactions between copper (in the concentrations of 2.5 μmol L-1 and 5 μmol L-1) and cadmium (5 μmol L-1) in common duckweed (Lemna minor L.) by exposing it to either metal or to their combinations for four or seven days. Their uptake increased with time, but it was lower in plants treated with combinations of metals than in plants treated with either metal given alone. In sep...
