A 6-hour application (6-hour pulse) of 1 millimolar azide significantly changed the phase of the potassium uptake rhythm of Lemna gibba G3. The phase response curve obtained was type 0 and very similar to that caused by a 6-hour pulse of low temperature (5 degrees C) or darkness. The magnitude of
The effect of Li(+) on the period of the K(+) uptake rhythm in the flow medium culture of the duckweed (Lemna gibba G3) was investigated under various ionic conditions. In the presence of Li(+) at 0.2 millimolar or higher concentrations, the period was longer than the normal level of 25.4 hours by 2
OBJECTIVE
A bioassay with duckweed (Lemna gibba L.) was used to study the effects of homeopathic potencies on the plant's growth rate. Screening included 12 substances: argentum nitricum, copper sulfate, gibberellic acid, 3-indole acetic acid, kinetin, lactose, lemna minor, methyl jasmonate,
Along with cadmium, lead, mercury and other heavy metals, chromium is an important environmental pollutant, mainly concentrated in areas of intense anthropogenic pressure. The effect of potassium dichromate on Lemna minor populations was tested using the growth inhibition test. Cyto-histological and
The use of wood as a sustainable biofuel results in the generation of residual wood ash. The ash contains high amounts of plant macronutrients such as phosphorus, potassium, calcium as well as several micronutrients. To explore the potential use of wood ash as a fertiliser, the growth enhancing
