Definitions

  • the invention relates to the use of 4-substituted-1-phenyl-pyrazole-3-carboxylic acid derivatives or their salts, to increase the stress tolerance in plants to abiotic stress, to enhance plant growth and / or to increase the yield of plants, and to specific processes for the preparation of the abovementioned Links. It is known that certain 1,4-diphenylpyrazole-3-carboxylic acid derivatives can be used as non-steroidal anti-inflammatory agents (cf.
  • 1-phenyl-4-alkylpyrazole-3-carboxylic acid derivatives can be used as pharmaceutical active substances for the treatment of ischemia (compare WO9943663) and for the treatment of parasites or as agrochemical active substances (see EP 933363).
  • 5-substituted-1-arylpyrazole-3-carboxylic acid derivatives are described as plant growth regulators in WO2005 / 063020. However, these differ fundamentally in the substitution of position 4 in the pyrazole ring.
  • the preparation of substituted 1,4-diphenylpyrazole-3-carboxylic acid derivatives is described in the references (see Synthesis 2009 (14), 2328-2332; Journal of Heterocyclic Chemistry 2007 44 (3), 603-607;

  • the response to salt stress involves phosphatases of the ATPK and MP2C types. Furthermore, in salt stress the biosynthesis of osmolytes such as proline or sucrose is often activated. Involved here are e.g. sucrose synthase and proline transporters (Hasegawa et al., 2000, Annu Rev Plant Physiol Plant Mol Biol 51: 463-499). The stress control of plants against cold and
  • Late Embryogenesis Abundant Proteins which include dehydrins as an important class, is known (Ingram and Bartels, 1996, Annu Rev Plant Physiol Plant Mol Biol 47: 277-403, Close, 1997, Physiol Plant 100: 291-296). These are chaperones that stabilize vesicles, proteins and membrane structures in stressed plants (Bray, 1993, Plant Physiol 103: 1035-1040). Moreover, induction of aldehyde dehydrogenases, which detoxify the reactive oxygen species (ROS) produced by oxidative stress, is often used (Kirch et al., 2005, Plant Mol Biol 57: 315-332).

  • HSF Heat Shock Factors
  • HSP Heat Shock Proteins
  • Substances or their stable synthetic derivatives and derived structures are also effective in external application to plants or seed dressing and activate defense reactions that result in an increased stress or pathogen tolerance of the plant [Sembdner, and Parthier, 1993, Ann. Rev. Plant Physiol. Plant Mol. Biol. 44: 569-589].
