Abstract

Seasonal production and nutrient concentrations of mushrooms in an Quercus acutissima forest were studied from 1999 to 2000. Thirty 2×2m quadrats were established randomly in the study area. 114 species of mushrooms were identified during the study period. Although mushrooms occurred from May to November in each year, the highest biomass production occurred in August. Seasonal dominant species was Lactarius violascens in June, R. bella and L. violascens in July, Marasmius siccus in August, Cortinarius tenuipes in September, Lepista nuda and C. tenuipes in October, respectively. Annual production of mushrooms in 1999 and 2000 were 84.8 kgDW·ha/sup -1/·yr/sup -1/ and 86.7 kgDW·ha/sup -1/·yr/sup -1/, respectively. Seasonal production was27.1kg/ha for July, 35.9kg/ha for August and 17.1 kg/ha for September, 3.7kg/ha for October, respectively. Seasonal dominant species in biomass was Russula alboareolata in June, R. bella in July, R. pseudodelica in August and September, Lepista nuda in October, respectively. R. pseudodelica showed the highest biomass in the study area, which is 17.5% of the total biomass. Average concentration of nutrients in mushrooms was 45.2mg/g for N, 1.5 mg/g for P, 29.6 mg/g for K, 0.2 mg/g for Ca and 0.8 mg/g for Mg, respectively, which were much higher than those in the leaf litter. Nutrients absorbed by mushrooms in 2000 was 4,163.1 g·ha/sup -1/·yr/sup -1/ for N, 130.1 g·ha/sup -1/·yr/sup -1/ for P, 2,568.2 g·ha/sup -1/·yr/sup -1/ for K, 12.4 g·ha/sup -1/·yr/sup -1/ for Ca, 68.5 g·ha/sup -1/·yr/sup -1/ for Mg, respectively.

1999년 3월부터 2000년 11월까지 공주시 근교의 참나무림에서 계절별 버섯의 출현종과 개체수, 생산량 및 영양염류 함량을 조사하였다. 조사기간 중 방형구 내에서 출현한 종은 114종류이었고, 총 개체수는 352,750개/ha이었다. 8월에 버섯의 출현종 수와 생산량이 가장 높았고, 출현한 개체수도 전체의 47%를 차지하였다. 월별 우점종은 6월과 7월에는 잿빛젖버섯, 8월은 애기낙엽버섯, 9월은 노랑끈적버섯, 10월은 노랑끈적버섯과 민자주방망이버섯이 우점하였다. 버섯의 연간 생산량은 1999년과 2000년에 각각 84.8 kg·ha/sup -1/·yr/sup -1/, 86.7 kg·ha/sup -1/·yr/sup -1/로 조사되었다. 버섯의 현존량은 7월, 8월, 9월, 10월에 각각 27.1, 35.9, 17.1, 3.7 ㎏/㏊이었다. 월별 현존량이 많은 종은 6월 횐꽃무당버섯, 7월 수원무당버섯, 8월과 9월 횐무당버섯아재비, 10월 민자주방망이버섯이었다. 연간 최대 현존량을 보인 버섯은 횐무당버섯아재비로 전체의 17.5%를 차지하였다. 버섯의 평균 영양염류 함량은 N 45.2±8.9 mg/g, P 1.5±0.8 mg/g, K 29.6±8.1 mg/g, Ca 0.2±0.3 mg/g, Mg 0.8±0.3 mg/g Ca과 Mg을 제외하고는 주변의 낙엽이나 토양보다 훨씬 높은 값이었다. 버섯을 통해 연간 임상에 축적되는 영양염류의 양은 N 4,163.1 g·ha/sup -1/·yr/sup -1/, P 130.1 g·ha/sup -1/·yr/sup -1/, K 2,568.2 g·ha/sup -1/·yr/sup -1/. Ca 12.4 g·ha/sup -1/·yr/sup -1/. Mg 68.5 g·ha/sup -1/·yr/sup -1/이었다.
