摘要(Abstract):

通过对霍山赤芝栽培品和野生品的外观性状和内部构造进行比较研究,为赤芝的深入研究提供参考。该研究采用性状观察、光学显微镜和扫描电镜等方法,比较霍山赤芝栽培品"霍芝一号"与野生赤芝的异同。结果表明,"霍芝一号"的菌盖颜色呈黄褐色、菌肉较厚,而霍山野生赤芝的菌盖颜色多以红褐色为主、菌肉较薄,且菌柄底部着生碎石和朽木;在光学显微镜下,赤芝栽培品和野生品均观察到清晰的骨架菌丝和缠绕菌丝,但未出现明显的差异;利用扫描电镜对赤芝栽培品和野生品的皮壳层、菌肉层和菌管层及孢子分别进行观察,发现"霍芝一号"的菌管壁较薄且形状不规则,而野生赤芝菌管壁整齐、致密,同时发现野生赤芝的孢子有2种类型,一种为保留了外壁的孢子Ⅰ型,表面具微小的凹孔,另一种为表面具有突起的孢子Ⅱ型,推测是Ⅰ型孢子脱落外壁所形成。该研究对霍山栽培和野生赤芝的外观性状和内部构造进行了系统的观察和比较,为赤芝栽培品和野生品的鉴别和品质评价提供理论依据和参考。
Through the comparative study on the appearance characters and internal structure of cultivated and wild Ganoderma lucidum in Huoshan,this paper provides a reference for the further study of G. lucidum. In this study,the similarities and differences between cultivated G. lucidum " Huozhi No. 1" and wild G. lucidum in Huoshan were compared by means of character observation,optical microscopy and scanning electron microscope( SEM). The results showed that the pileus color of " Huozhi No. 1" was yellowish brown and thicker,while that of wild G. lucidum was mainly reddish brown,the context was thinner,and there were gravel and rotten wood at the bottom of the stipe. A clear skeletal hyphae and binding hyphae were observed in cultivated and wild G. lucidum,but there was no significant difference. The shell layer,context layer,mediostratum layer and spores of cultivated and wild G. lucidum were observed by SEM,and the results showed that there was no significant difference. It was found that the mediostratum of " Huozhi No. 1" was thin and irregular,while the mediostratum of wild G. lucidum was neat and compact. There were two types of spores in wild G. lucidum,one of which retained the outer wall of spore type Ⅰ,with tiny pores on the surface. The other is type Ⅱ spores with many spinous processes on the surface,which may be formed by type Ⅰ spores falling off the outwall. In this study,the appearance characters and internal structure of cultivated and wild G. lucidum in Huoshan were systematically observed and compared,which provided theoretical basis and reference for the identification and quality evaluation of cultivated and wild G. lucidum.
