【英文摘要】 High CO_ 2 concentrations strongly inhibited the formation of Flammulina velutipes primordia and were also harmful for mushroom development, resulting in smaller fruit body caps and thinner stipes. Our data suggest that CO_ 2 concentrations should be maintained between 0.03～0.134 % at the time of primordia development, and between 0.134～0.448% during fruit body elongation. Cultivation of F. velutipes in pear refrigerated warehouses (PRWs) with limited ventilation resulted in CO_ 2 accumulation to levels that adversely affected fruit body formation and growth, and ultimately mushroom quality. Relatively minor modifications to improve the ventilation capacity of the PRWs, combined with spraying with Ca(OH)_ 2 solution, allowed CO_ 2 concentrations to be controlled at levels suitable for commercial mushroom production.
