最近,我们在实验室诱变获得了一株佛罗里达侧耳无孢子突变体。这种无孢子突变体对商品性侧耳栽培种而言,是十分理想的。Eger,1977;Ohira,1979;Sakula,1967;Schichijo等1969,1970;Grabbe和Zadrazil,1977已发现,多种伞菌包括侧耳、香菇和双孢蘑菇会弹射出孢子引起人体呼吸道产生病变。双孢蘑菇的子实体菌褶由菌膜覆盖,子实体通常在菌膜破裂前(即菌蕾阶段)采摘,因 Recently, we obtained a strain of Florida Pleurotus aestivum mutagenized in laboratory. This spore-free mutant is ideal for commercial otter cultivation. Eger, 1977; Ohira, 1979; Sakula, 1967; Schichijo et al., 1969, 1970; Grabbe and Zadrazil, 1977. Various types of toadstools including Pleurotus ostreatus, mushrooms and Agaricus bisporus have been found to eject spores causing lesions in the human respiratory tract. Agaricus bisporus fruiting body folds covered by the bacterial membrane, fruiting bodies usually in the rupture of the membrane before (ie, bacterial bud stage) picking, due to
