Effects of red and far red lights on nodulation and nitrogen fixation in soybean (Glycine max L.Merr)

  • P. A. Balatti
  • E. R. Montaldi


Rooted leaves and plants were irradiated at the end of the photoperiod with red light for 15 minutes, while another group was also irradiated with red light and immediately afterwards with far- red light.

The reduction in Pfr/Ptotal established by far red irradiation promoted nodulation probably by affecting an hormonal balance.
