Scholarcy highlights

  • The gibberellin content of the reproductive organs ofCitrus sinensis Osb., cv
  • Gibberellins A1, A20, and A29 were identified in the reproductive buds of both cultivars 21 days prior to anthesis and in fruits 35 days after anthesis by comparison of their mass spectra and Kovats retention indices with those of standards
  • The presence of GA4 in both tissues, and of GA8 in the reproductive buds, was indicated by the occurrence of characteristic ions at the expected retention times, their spectra were too weak for full identification
  • The maximum GA1 concentration occurred at anthesis
  • Highest concentrations of gibberellins A20 and A4 were found in fruit 35 days after anthesis, the GA1 concentration at this stage remained low
