Bletilla striata var. Alba is a variant of B. striata which possesses high ornamental and medicinal value. However, there have been no reports on its seed germination and propagation to date. In this study, using the seeds of B. Striata var. Alba as the experimental material, indoor seed germination tests and pot tests were carried out to investigate the effects of mycorrhizal fungi from different sources (MB-15, MB-18, MH1-E and YDLXB) on seed germination and seedling growth. The results demonstrated that various mycorrhizal fungi had different effects on promoting the germination of B. striata var. Alba seeds. Among them, the Sebacina fungus MB-18, derived from the roots of B. striata, exhibited an extremely significant promotional effect. Compared with the control treatment, the germination rate and seedling formation rate in the petri dish experiment increased by 10.76% and 20.55% respectively, while in the pot validation test was 36.95% and 355.78%, respectively. Moreover, when sown directly, the seeds of B. striata var. Alba could germinate, but the seedling formation process was hindered. However, compatible mycorrhizal fungi (MB-15, MB-18, MH1-E and YDLXB) effectively promoted the formation of seedlings. The results are of great significance for the germplasm conservation, large-scale seedling breeding and sustainable utilization of B. striata var. Alba.
