Abstract

The mushroom takes in charge of decomposer in ecosystem and its production is important indicator for sounded ecosystem function. To determine standing crop of basidiocarps(fruit body of mushroom), a weight must be measured by harvesting mushroom individual in the field. But this method has profound affection on the basidiocarps population or its surrounding condition due to habitat destruction. Thus, in this study, without harvesting any mushroom in the field, we developed allometric equation using some morphological parameters to estimate standing crop biomass of basidiocarps. Lentinula edodes, Pleurotus ostreatus, Flammulina velutipes and Conocybe tenera were used for allometry. Morphological variables of the mushroom were pileus diameter, pileus area, stipe length and stipe thickness. Consequently, all the experimental mushrooms species showed significantly correlation in biomass estimation of basidiocarps from allometric equation (p<0.05). As a result of this research, the standing biomass of the basidiocarps could be indirectly estimated with proportional expression, allometric equation drived from morphological characters.

버섯은 생태계에서 분해자로 역할을 담당하며, 그 양은 생태계의 건전성을 나타내는 중요한 지표이다. 버섯의 생산량을 알기 위해서는 개체를 수확하여 그 무게를 측정하여야 한다. 그러나 이 방법은 버섯 개체를 수확할 때 서식지를 훼손하고, 또한 한 지역에서 버섯의 동태를 장기적으로 관찰하는데 적합하지 못하다. 따라서 본 연구에서는 자실체의 외부 형질을 측정하고 이로부터 현존량을 추정하는 비례식을 만들었다. 사용한 버섯은 표고(L. edodes), 느타리(P. ostreatus), 팽이버섯(F. velutipes)과 종버섯(C. tenera)이다. 버섯의 자실체에서 형질 변수(갓 직경, PD; 갓 면적, PA; 대 길이, SL; 대 두께, ST)를 측정하고, 이 변수로부터 건조 생물량과의 회귀관계식을 구하였다. 그 결과 버섯 4종 모두 추정한 식에서 유의한 상관성을 보임으로써(p < 0.05), 외부 형질 변수로부터 유도된 비례식을 사용하여 버섯의 현존량을 예측할 수 있음이 확인되었다.
