THE INFLUENCE OF ANCYMIDOL ON MORPHOLOGY, ANATOMY, AND CHLOROPHYLL LEVELS IN DEVELOPING AND MATURE HELIANTHUS-ANNUUS LEAVES Academic Article uri icon

abstract

  • Ancymidol foliar spray at 132 mgliter-1 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. 1990 Kluwer Academic Publishers.
