    Notes: Abstract In the presence of ethylene, which enhances carnation flower senescence, carbohydrates contribute to ovary growth not only from the stem and calyx but also from the petals. With silver thiosulphate and ethanol treatments which delay flower senescence, the petals remain the active sink and ovary development is suppressed. Ethylene stimulated chloroplast development in the ovary wall. However, the calyx plus stem of all treatments showed the greater photosynthetic ability and transported a major portion of the synthesised products to the ovary.

    Cytokinins in cut carnation flower III. The influence of indoleacetic acid on growth, cytokinin content and metabolism of 14C-benzyladenine in cultured ovaries (1987)

    Keywords: Dianthus caryophyllus ; cytokinins ; (8-14C)-benzyladenine ; auxin ; indoleacetic acid ; ovaries

    Notes: Abstract Exogenous applications of auxin to in vitro grown carnation ovaries resulted in an increase in dry mass and a decrease in the levels of endogenous cytokinins within the ovaries. Untreated ovaries showed no significant increase in dry mass. There was however, an increase in endogenous cytokinins over the same period. When 14C-BA was applied to ovaries both with and without exogenous auxin the pattern of growth and cytokinin changes followed a similar trend. Although the BA-metabolites were similar in both treatments, degradative metabolism of the cytokinin was faster and the increase in ovary dry mass greater when auxin was included in the treatment.
