Changes in Sporophore Appearance of Cultivated Mushroom, Agaricus bisporus, during the Harvesting Period

양송이 자실체(子實體) 발생(發生)의 경시적(經時的) 변동(變動)에 관한 연구(硏究)

This stuy was conducted to analyse the variation in occurrance of fruit body of Agaricus bisporus (Lange) Sing, depending on difference of cultivation and harvesting method and to find out a method for early predicting the mushroom yield potential at the base of results of the analysis. The results obtained were as follows ; 1. Total mushroom yield was highly correlated with picking amount of fruit bodies during first 30 days of picking period, and yield potentiality in the certain high yielding mushroom house was markedly affected with the yield of middle and late period of picking. 2. Variation of mushroom yield with varying the degree of maturity of fruit bodies appeared to be different between spring and autumn cropping : in case autumn cropping was usally undertaken with normal cropping scheme, mushroom yield showed a reduction in early period of picking but an increase in late period when the mushrooms where picked at pre-matured stage. 3. When the picking rate of button form was laid in the range of 20~45%, and increase of total mushroom yield was accompanied by an increasing tendency of picking rate of button form. 4. Cropping results from mushroom houses could be early predicted from the regression equations, which was based on the analysis of variation in fruit body occurance throughout the picking period.

1. 본(本) 연구(硏究)는 양송이의 재배(栽培) 및 수확방법(收穫方法)이 다를 때 자실체발생(子實體發生)의 변동상(變動相)을 밝히고 수량(收量)의 조기예측방법(早期豫測方法)을 확립(確立)하고자 실시(實施)하였다. 2. 양송이 수량(收量)은 최초(最初) 30일간(日間)의 채취량(採取量)과 상관(相關)이 높고 다수확재배사(多收穫栽培舍)의 수량구성(收量構成)에 있어서는 중후기(中後期)의 채취량(採取量)과 다소(多小)가 큰 역할(役割)을 하였다. 3 채취시기(採取時期)에 따른 수량(收量)의 변화(變化)는 재배시기(栽培時期)에 따라 다르나 작업관리(作業管理)가 정상상태인 추기재배(秋期栽培) 때는 어린 버섯을 채취(採取)하므로서 초기수량(初期收量)은 감소(減少)하고 후기채취량(後期採取量)은 증가(增加)하였다. 4. Button 채취비율(採取比率) 20~45% 범위(範圍)에서 전수량(全收量)이 증가(增加)하면 Button 채취비율(採取比率)도 증가(增加)하는 경향(碩向)을 보였다. 5 양송이 재배합(栽培舍)은 자실체발생(子實體發生)의 변동(變動)을 조사(調査)하여 재배결과(栽培結果)의 조기예측(早期豫測)을 위한 회귀식(回歸式)을 산출(算出)하였다.
