STUDY ON SYMBIOTIC RELATION BETWEEN GASTRO-DIA ELATA AND ARMILLARIELLA MELLEABY AUTORADIOGRAPHY
蜜环菌和天麻共生营养关系的放射性自显影研究

Gastrodia elata Bl. was labelled by 3H-glucose with pouring method. After labelled G. elata was cultured together with Armillariella mellea (Vahl: Fr.) Karst., observation was made by autoradiography to see whether labelled materials appeared in rhizomorphs of A. mellea. The results showed that G. elata absorbed labelled materials which were transported by vascular tissue. We found that there were silver grains deposited in rhizomorphs of A. mellea. The fact proves that A. mellea obtains nutrient from G. elata, which suggests special symbiotic relation between G. elata and A. mellea.
