UEDA Keiko,Taketoshi UMEDA,Shinsuke HIROMATSU and Yasuhiro MORI (Fukuoka Agriculture and Forestry Research Center,Kurume,Fukuoka

To investigate the possibility of shortening the incubation period of Pholiota adiposa “Fukuoka O-N” by 14 days, we cultivated“Fukuoka O-N” that was incubated for 56 days after inoculation and examined the crop duration, number of stipes, and fruit bodyyield. There were no significant differences in these indices between crops incubated for 56 days and those incubated for 70 days,
which were used as the control. To estimate the physiological activities in the hyphae, the concentration of CO 2 that was released
from the hyphae in the culture bottles was periodically measured using an O2/ CO2 analyzer during incubation after inoculation withthe spawn “Fukuoka O-N”. The CO2 concentration rapidly increased at the beginning of the incubation period and reached amaximum 14 days later. Thereafter, it sharply decreased up to 35 days and then gradually decreased up to 70 days. These results
suggest that until the 35th day, the hyphae actively grew, and at the 56th day they were at the same maturation level as that on the70th day. From these results, we suggest that it is possible to shorten the incubation period of P. adiposa “Fukuoka O-N” by 14 days
with no negative results in the yields.
