天麻种子发芽营养来源的研究

Studies on Nutrition Source of Seeds Germination of Gastrodia elata BI.

天麻种子无胚乳及其它营养贮备,发芽非常困难。蜜环菌有抑制种子发芽的作用。天麻种子属共生萌发类型,种子发芽的营养,来源于消化侵入种胚细胞的紫萁小菇(Mycena osmundicola Lange),壳斗科(F(?)gace(?)e)植物的树叶是紫萁小菇良好的培养基,是种子萌发的间接营养来源。

The seeds of Gastrodia elata lack an endosperm and other stored nutrition and thus do not easily germinate. Armillaria mellea inhibit germination of the seeds, which exist in a type of symbiotic relationship with fungi. The nutrition necessary for germination is derived from Mycena osmundicola invading cells of the embryo. The tree leaves provide a good medium for Mycena osmundicola growth and an indirect nutritional source for germination.
