Species Info

  • Shorea affinis (native; endandered)
  • Shorea congestiflora (native; critically endandered)
  • Shorea cordifolia (native; critically endandered)
  • Shorea gardneri (native; critically endandered)
  • Shorea zeylanica (native; critically endandered)


  • This study examines whether the degree of ectomycorrhizal (EM) colonization of potted Shorea spp. was associated with the amount and quality of daily photosynthetic photon flux density (PFD).
  • Five species (Shorea affinis,S. congestiflora, S. cordifolia,S. gardneri, and S. zeylanica) were grown in pots for two years under well-watered conditions in five different shade treatments: deep shade, light shade, short duration direct light, long duration direct light, and full sun.
  • Results show that the percentage EM colonization was significantly different among shade treatments, for all five species ( p < 0.05). However, EM root colonization was not significantly different among species.
  • Highest percentages of EM colonization for all species, except for S. congestiflora, were in treatments providing full open conditions. However, seedling growth of all species were best under partial shade conditions.
