✦ Synopsis

Ancymidol foliar spray at 132 mg • liter -' a .i . modified leaf anatomy of developing Helianthus annuus L . `Mammoth Russian' leaves, but not of mature leaves . Ancymidol was effective in retarding plant growth when applied at the young seedling or at a more mature stage of growth . Ancymidol increased leaf weight per unit area and chlorophyll content on an area and unit weight basis, regardless of stage of leaf development . Total chlorophyll per leaf was also increased in mature leaves . Thus, darker green foliage due to increased chlorophyll content and modified leaf anatomy responses were determined to be independent effects .
