THE recently characterized plant growth inhibitor, abscisic acid1,2, has been shown to occur in the phloem sap of willow by spectropolarimetry of a purified aphid honeydew extract3. The pronounced Cotton effect exhibited by abscisic acid4,5 provides a highly specific test for the presence of this compound in plant extracts, but relatively few plant physiology laboratories are equipped with facilities for spectropolarimetry. Many laboratories, however, possess equipment for gas–liquid… CONTINUE READING
