摘要:The first object is to provide an inhibitor of the synthesis of endogenous auxin. The second object is to provide a plant growth inhibitor or a herbicidal agent utilizing the auxin biosynthesis inhibitor. Thus, disclosed are: a method for screening a candidate for an auxin biosynthesis inhibitor capable of inhibiting the expression of an auxin-inducible gene, by adding each of candidate compounds for the auxin inhibitor to a plant; a method for selecting a compound capable of actually inhibiting the auxin synthesis in a plant, by adding each of candidate compounds to the plant, disrupting the plant and then measuring the amount of endogenous auxin; and a method for selecting a compound capable of inhibiting the production of indolpyruvic acid in the presence of a tryptophan deaminase and tryptophan which are prepared in advance. More specifically disclosed are: an auxin biosynthesis inhibitor comprising AVG, AOA, AOIBA, L-AOPP or an analogue thereof; and a plant growth regulator or a herbicidal agent comprising the compound as an active ingredient.

摘要:Our discovery concerns the method of synthesis and the application of new chemical products for plant growing. These new products are polymeric derivatives of low molecular weight plant growth regulators and are characterized by slow release of the auxin from the polymeric carrier. By copolymerisation of allylic esters of the low molecular weight auxins with the acrylic (or the methylacrylic) acid and the following modification of the synthesized co-polymers of acids to their corresponding ammonium salts, water soluble polymeric auxins possesing optimal molecular weight and desirable (high) content of the low molecular weight auxin in the polymer were prepared. The method of synthesis and the final products fulfill the requirements of the preparation technology and of their application respectively. We suggest the application of the new products in agronomy (i.e. treatment of seeds, rootstocks, plants, scions, cutting etc) either by themselves or by combination of them with other chemicals. The chemical structure of the new products we discover is :n n    R = H-, -CH3, Au = auxin residue
