Název v původním jazyce

Occurrence of nutrients and plant hormones (cytokinins and IAA) in the water fern Salvinia molesta during growth and composting.

Popis výsledku v původním jazyce

The aquatic fern Salvinia molesta is classified as an invasive, noxious weed in southern Africa. It has rapid growth and forms a thick mat in slow moving water bodies. It is hypothesized that S. molesta is a suitable candidate to promote as an organic fertilizer. The aims of this study were to determine the mineral content as well as the cytokinin and auxin content in S. molesta. The release of these compounds into the culture medium and upon decomposition of the air-dried plant matter was also determined. Minerals detected in the fresh plant material were N > K > P > Ca > Mg > Fe > Na > Cu > Zn while Cd, Pb and Ni were below the level of detection. The mineral concentrations changed after 14 days decomposition with there being an increase in Ca, Mg and Fe and a decrease in K. Sixteen isoprenoid cytokinins were detected in the plant material (total concentration 81.62 pmol/g DW) while only four cytokinins occurred at a greatly reduced concentration in the culture medium (4.31 p
