摘要:
AbstractMonoclonal cultures ofFossombronia brasiliensiswere grown with different photoperiods, temperatures and inorganic nitrogen sources. The subsequent vegetative growth and production of gametangia is described. A quantitative analysis of the numbers of antheridia and archegonia and their relative proportions is given. At 18°C,F. brasiliensiswas found to be a short-day plant, with a critical night length of between six and twelve hours, while at 10°C it exhibited quantitative SD plant properties. Plants produced more male gametangia at 18°C and more female gametangia at 10°C. Nitrogen as nitrate consistently produced more gametangia than the ammonium source.
