| Abstract:
Six cultivars of Chrysanthemum have been grown in three different concentrations of recirculated nutrient solution. The nutrient content in the solutions as well as the content of the plants was analyzed at intervals during the growing period. The plants seems to be very tolerant to variation in the nutrient concentration. To a certain extent a lack of potassium seems to be compensated for by increased uptake of calcium and magnesium. The major inorganic elements decreased during the growing period probably because of dilution by organic matter formed. Contrary to the other elements the content of iron, manganese, zinc and copper in the plants increased during the growing period. - The plants grown in the two weakest solutions got yellow leaves indicating iron deficiency. This could not, however, be confirmed by plant analyses. | |
