ResumoThe short-day plant Lemna paucicostata 6746 took up the same amount of copper from the medium whether the pH of the medium was 4.1 or 5.1. At pH 4.1, an addition of copper to the medium resulted in an unchanged chlorophyll content, a somewhat reduced growth rate and a substantial induction of long-day flowering. By contrast, at pH 5.1 the same copper concentration caused a reduction in the chlorophyll content and strong inhibition of growth, but it did not induce any long-day flowering.
