Abstract
Abstract Phosfon retardation of growth was studied in 2 cultivars of Chrysanthemum morifolium Ramat., ‘Jet Fire’ and ‘Maple Leaves’. Retarded growth of ‘Jet Fire’ was the result of fewer and shorter internodes, whereas in ‘Maple Leaves’ the number of internodes remained the same but their length was less compared to the controls. In both cultivars, the shorter internodes were the result of a reduction in cell division and hence cell number. The length of cells in the pith of fully developed internodes remained the same. Application of gibberellin overcame the growth retarding effect of phosfon while indoleacetic acid was ineffective. Combined applications of gibberellin and indoleacetic acid had the same effect on growth of phosfon-treated plants as gibberellin alone. The gibberellin content of the shoot apex was much less in phosfon-treated plants, but there was a larger reduction in the gibberellin content in ‘Jet Fire’ than in ‘Maple Leaves’. Protein, RNA and DNA contents of the leaves and apices were determined colorimetri-cally and there were no measurable differences as a result of phosfon treatment.
