  Author(s): Sandeep Jain*, Pooja Salaria, Ritu Rani and Rachana D Bhardwaj
  
  Sudden wilt syndrome of chilli pepper is an emerging disorder characterized by unexpected and abrupt wilting of plants due to water stagnation and resultant hypoxic conditions in the rhizosphere. This problem is further exacerbated by infection of soilborne fungus Fusarium oxysporum, which is not the primary cause. The study is an attempt to investigate physiological and biochemical alterations in three test organs (roots, leaves and fruits) of chilli pepper in response to sudden wilt syndrome. The sudden wilt-affected plants had lower levels of total phenols, o-dihydroxyphenols, flavonoids, ascorbic acid, peroxidase, polyphenol oxidase, catalase, phenylalanine ammonia lyase, tyrosine ammonia lyase, polyphenol oxidase, lignin, moisture content in leaves, Relative Water Content (RWC), Membrane Stability Index (MSI), chlorophyll A and B and the gas exchange parameters (net phot..
