一、天麻种子萌发与生长机理 天麻种子萌发初期,紫萁小菇菌侵入种子皮层,集结在胚末端胚柄细胞外围,使种子得到足够的营养,分生细胞迅速分裂,突破种皮,逐步形成初生原球茎。经继续生长发育后产生次生原球茎和营养茎。次生原球茎和营养茎在得到密环菌丝体营养后就完成了种子生长发育周期。 二、紫萁小菇的生物学特性与人工培育 紫萁小菇属口蘑科,小菇属真菌,子实体散生残丛生,呈半球形,灰色,柔软。菌丝无色透明有分隔。 紫萁小菇菌能为天麻种子萌发提供营养,在生产中应用又称天麻种子萌发菌。 人工培育萌发菌就是采集紫萁小
First, the germination and growth mechanism of Gastrodia elata Germplasm initial stage of germination, Agkistrodon acreus invade the seed cortex, the end of the embryo in the end of embryonic stem cell aggregation, the seeds get enough nutrition, meristematic cells rapidly split, breaking the seed coat, and gradually formed Primary protocorm. After continued growth and development produce secondary protocorm and nutrition stems. Secondary protocorm and nutrition stems get dense mycelium nutrition to complete the seed growth and development cycle. Second, the biological characteristics of Aster mushroom and artificial cultivation Aster mushroom Mushroom, Capillaris fungi, fruiting bodies loose residual clusters, was hemispherical, gray, soft. Mycelium colorless and transparent with separation. Aster mushroom can germinate Gastrodia seed germination to provide nutrition, in the production of gastrodia seed germination bacteria, also known as. Artificial germination germination is collecting Aster small
