Abstract
-
1.
Growth of the floating aquatic weed, Salvinia, in sterile culture was exponential for at least 2 weeks under standardized conditions.
-
2.
Increase in light intensity or in CO2 resulted in increases in growth rate, but did not extend the exponential period of growth.
-
3.
This aquatic plant, like many others, discriminates against calcium relative to strontium.
-
4.
In culture Salvinia exhibited luxury consumption of N and P.
-
5.
Because of high C/N ratios, Salvinia may not be a favorable source of animal food, but might be useful in nutrient removal schemes.
-
6.
In sterile culture, S. molesta produced fewer leaves than S. minima, but maintained a significant increase in leaf area and dry weight. This may be correlated with the ability of the first species to rapidly spread over tropical waterways.
