Abstract
When the long-day plant Lemna gibba L., strain G3 is grown under continuous light on ammonium-free half-strength Hutner's medium (NH4+-free 0.5 H medium) growth is excellent, but flowering is severely inhibited and often is zero. Addition of 10 micromolar salicylic acid (SA) to NH4+-free 0.5 H medium quickly reverses this inhibition and leads to optimal flowering. The SA treatment also leads to a considerable reduction in the growth rate and increase in frond gibbosity. Removal of SA from the medium quickly leads to an increase in the growth rate and a large decrease in flowering. Thus, for maximal effectiveness SA must be present in the medium for the entire experiment, and the effect of SA is clearly not inductive.This publication has 4 references indexed in Scilit:
