Effect of Ancymidol on growth and chlorophyll content of Helianthus annuus L. in water culture experiments Height of young sunflower plants in water culture was shortened up to 30 % by 0,75 ppm ancymidol in the nutrient solution. The chlorophyll concentration of the aerial plant parts increased from 15 to 30 %under the influence of 0,75 ppm ancymidol, the amount of chlorphyll per plant however was not changed compared with the control. The reduced height of the ancymidol plants was accompanied by a reduced fresh weight, in some cases also by a lowered dry weight of plants. Dry weight of the roots of ancymidol plants was not changed.
