plants can express resistance to pests by biosynthesizing allelochemicals. they may be normally present, or their biosynthesis may be elicited or enhanced by injury. this work was initiated to develop a more rapid, integrated approach to identify chemicals that are responsible for resistance to pests, or that are associated with stress. intact tissues were subjected to histochemical evaluations with a spectrum of class specific reagents. treatments gave chromophores in solution that could be semiquantitated. stains of the tissues were also obtained in this process and evaluated alternately, surface chemicals of the plant tissues were selectivity removed by dipping in solvents and chromatographed in appropriate tlc systems. characteristic colors were developed with diagnostic spray reagents. 8 refs
