RESUMEN
OBJECTIVE: To study on the relationship between the endophyte and the life cycle of Ophiopogon japonicus in Zhejiang. METHODS: Sample roots of Ophiopogon japonicus at different growth stages were thoroughly washed and cut into small fragments, then cleared (removing cytoplasmic contents from cells) using hot 10% KOH and stained with acid fuchsin (alternative stain). The hyphae, the arbuscular and the vesicular of endophyte were examined. RESULTS: The hyphae appeared and grew in the seedling stage, the hyphae grew into arbuscular in the root tuber generating stage and vesicular in the stage of root tuber expanding period. CONCLUSION: The endophytes in Ophiopogon japonicus appeared in forms of hyphae, arbuscular and vesicular at different growth stages to meet the needs of Ophiopogon japonicus developing.
