Abstract

The aseptic seed germination ofGaleola septentrionalis was observed only in an airtight vessel at 30 C, germination being enhanced with increasing air pressure in the vessel up to the optimum of 1.8 atm. The presence of O2 and CO2 was essential for germination, and their optimum concentrations were 5 and 8%, respectively. The optimum pressure for germination (1.8 atm) was not influence by the composition of the air. Ethylene added at concentrations ranging from 2 to 8μl/l enhanced germination and its removal reduced the germination.

The atmospheric condition required for the seed germination of this orchidin vitro was discussed with regard to that in its natural habitat.
