(十) 高溫菇據國內外學者之鑑定確屬Agaricus bitorquis，再經生物及加工食用有關試驗資料，確定可供食用。
In order to closely examine a) the effect of environmental factors on mycelial growth and fructification, b) the relationships between the yield and both the rate of spawning and season of cultivation, as well as c) the quality of processing product of a new mushroom,which has been identified as Agaricus bitorquis by ATCC, many experiments were carried out and the conclusions are described as follows
1. The optimum temperature for mycelial growth was 30°C; no growth from the innoculum was observed at the temperature lower than 15°C or upper than 40°C in 15 days; the highest critical temperature. for mycelial growth was 39C.
2. The mycelia grew well in the pH range of 5.1 to 7.0, but poorly when the pH value was lowered to 4 or raised to 10.
3. Normal rnycelial growth was obtained when the water content of the compost was strikingly adjusted to 56-79%, with an optimum at 56%, but the growth was limited when the water content was lower than 45%.
4. Potato-compost-dextrose agar medium was excellent for mycelial growth among the media being tested, both the compost agar medium and corn agar medium were suboptimum and the Czapek agar medium was bad for mycelial growth. The mycelia grew slowly, but easily developed primordia on PDA.
5. A great number of primordia or pinheads were obtained on agar media if the culture was put at 30°C, however only a few primordia were observed when the temperature was lowered to 25°C or raised to 35°C. The primordium could hardly be observed if the culture was put at the temperature lower than 20°C.
6. The formation of primordia was not evidently affected by change in temperature during inocubation in the range of 25 to 35°C.
7. The initiation of fruiting was not closely related to light. The culture could initiate fruiting on agar media when it was subjected to different light intensity of 0-1000 Lux. However practically it was usually exposed to 50-100 Lux for the convenience of the management of cultivation.
8. With the respect to the experiment on the relationship between the yield and the rate of spawning, it was observed that there was no significant difference in yield when the compost was spawned at the rates of 2 to 16 bottles (350 gram/bottle) per pin (ca. 3.24m2) . In practical application, the most economic spawning rate is 2 bottles of spawn per pin.
9. From April to October the climatic conditions are suitable for cultivation of Agaricus bitorquis in Taiwan.
10. The quality of dehydrated product of the new mushroom A. bitorquis obtained by subjecting the slices of fruit—bodies to quick freezing and drying could be compared with that of dehydrated mushroom of A. bisporus. However, the canned product with whole mushrooms of the former was not so good as those of the latter due to the presence of thin membrances on the pileal surface of the former. It would he better if the mushrooms of the former were cut into slices.
