신품종 느타리버섯의 생육온도에 따른 호흡특성 비교

Comparison of respiration characteristics on the new variety of oyster mushroom according to the growth temperature

생육온도가 증가함에 따라 $CO_2(ppm/hr/m^3$/병)농도는 증가하였고, 생육단계별로는 생육후기에 가장 높은 경향을 나타내고 있으며, 품종별로 춘추2호<수한2호<청풍<진미<흑백 순으로 호흡량이 많은 경향을 나타내었다. 또한 생육 온도가 높아짐에 따라 $O_2(ppm/hr/m^3$/병)소비량은 증가하는 경향이었으며, 생육단계별로 생육후기에 가장 많이 소비되는 경향을 보이고 있고, 품종별로 춘추2호<수한2호<청풍<진미<흑백 순으로 소비된 $O_2$량이 많아지는 경향이었다. 그리고 느타리버섯의 생육적정 온도인 $15^{\circ}C$에서의 호흡지수는 춘추2호가 500일 때, 수한2호 528, 청풍 573, 진미 617, 흑백 634로 신품종의 호흡지수는 춘추2호 보다 높은 경향을 나타내었다.

This study was carried out to find out respiration characteristics of new variety of oyster mushroom to the temperature response. In new species of oyster mushroom, the account of respiration was on the increase when the growth temperature with the passage of growth stage was on the rise. The $CO_2$ concentration was accelerated as increasing the growth temperature, whereas the $O_2$ concentration was decreased. The account of respiration of new variety was in the descending order, Hukbaek>Jinmi>Chungpung>Suhan2>Chunchu2. Also, the ventilation exponent at $15^{\circ}C$ was Suhan2 2 ~12%, Chungpung 9~24%, Jinmi 15~37%, Hukbaek 17~39% in proportion to Chunchu2. The experiments related to respiration characteristics of new variety of oyster mushroom were worthy of recommending to new variety cultivator.
