Two outdoor shiitake (Lentinula edodes) cultivation experiments, established in Missouri USA in 1999 and 2000, produced mushrooms in 2000-2005. We examined shiitake production in response to substrate species, inoculum form, inoculum strain, and inoculation timing, using total mushroom weight per log as the primary response variable with log characteristics as covariates. The significantly greater mushroom weight produced by sugar maple logs compared with white or northern red oak was attributable to the higher proportion of undiscolored wood volume in the maple logs, rather than to bark thickness or log diameter. The "wide temperature range" shiitake strain produced significantly greater yield compared with the "warm" or "cold" weather strains. Both the wide-range and warm-weather strains were stimulated to fruit by significant rain events, while the cold-weather strain was responsive to temperature. Inoculation with sawdust spawn gave significantly greater yield than colonized wooden dowels or pre-packaged "thimble" plug inoculum. The second and third full years following inoculation were the most productive.
1999年和2000年在美国密苏里州开展了两项室外香菇栽培试验，并于2000年至2005年收获了香菇。我们以每根原木的香菇总重量作为主要响应变量，以原木特征作为协变量，研究了香菇产量对基质种类、接种体形式、接种菌株和接种时间的响应。与白橡木或北方红橡木相比，糖枫原木产生的香菇重量显著更高，这归因于枫木原木中未变色木材体积的比例更高，而不是树皮厚度或原木直径。“宽温度范围”香菇菌株的产量显著高于“温暖”或“寒冷”天气菌株。大量降雨事件刺激了宽温度范围菌株和温暖天气菌株出菇，而寒冷天气菌株对温度有响应。接种木屑菌种的产量显著高于定殖木钉或预包装“顶针”塞接种体。接种后的第二和第三个完整年份产量最高。
