Abstract

Since the market price of H. marmoreus has fallen, it is suggested by us that H. marmoreus is dealt on basis of its shape. We researched the shape of H. marmoreus desired by the consuming public. To produce such H. marmoreus, relationships between he shape of H. marmoreus and the density of carbon dioxide gas in terms of budding were researched in our experiments. These data are shown in figures 4 to 7.<BR>In this paper, the triangular fuzzy numbers are used. They are shown as (the lowest limit value, the most probable value, the supremum value). The best height (mm) Of H. marmoreus was obtained as (36.3, 48.2, 59.8). Let xp be the concentration of carbon dioxide gas (100 ppm), and h be the membership function of fuzzy model : the fuzzy model Y1 (xp) which shows the relationship between the height and xp is as follows : <BR>Y1 (xp) = (23.571, 4.200/ (1-h)) L+ (0.23810, 0)) Lxp+ (0.12351, 0.018750/ (1-h)) Lxp2 (13) <BR>So, to produce the desirable H. marmoreus, the best concentration of carbon dioxide gas was obtained as (1163, 1319, 1419). The best diameter (mm) of stem was obtained as (6.9, 8.6, 103). Then, the fuzzy model Y2, (xp) on the diameter of stem is as follows : <BR>Y2 (xp) = (30.671, 3.7857/ (1-h)) L- (2.833, 0.14286/ (1-h)) Lxp+ (0.090476, 0) Lxp2 (14) <BR>So, the best concentration of carbon dioxide gas was obtained as (1440, 1455, 1457) or (1530, 1675, 1833). The best diameter (mm) of cap was obtained as (11.5, 13.7, 15.8).Then, the fuzzy model Y3 (xp) on the diameter of cap (mm) is as follows : <BR>Y3 (xp) = (35.214, 5.2143/ (1-h)) L- (0.07093, 0.0084325/ (1-h)) Lxp2 (15) <BR>So, the best concentration of carbon dioxide gas was obtained as (1720, 1742, 1761).<BR>From the analyses described above, it is concluded that when the concentration of carbon dioxide gas are set from the center to the supremum of ordinary limit, the desirable H. marmoreus is made.
