Acompletely randomised design, having three treatments and seven repeats per treatment, was used for determining chlorophyll a fluorescence in broccoli plants affected by iron toxicity. One month old Legacy hybrid broccoli seedlings (Brassica oleracea var. Italica) were taken as initial vegetal material and sown in a greenhouse in Tunja, Colombia, in glass vessels containing a nutritive solution. Iron sulphate at 100 and 250 ppm Fe concentration was added about three weeks after transplanting (as well as control with out iron sulphate) for inducing reactions to the excess of metal in the plants. Chlorophyll fluorescence was measured in leaves which were fully expanded and adapted to the dark seventeen days after applying Fe. Analysis of var...
