The results showed that centrifugal (≤14 000 r·min-1, ≤30 min) almost had no influence on spore germination; Sterilizing spore surface for 10-20 min with 1% NaClO was the best sterile method; Modified Knop’s medium was the best for spore germination; Spore could not germinate in dark, but the dark treatment could improve the regularity of spore germination; Red light could promote spore germinating about 1 day earlier than white light, but had no obvious influence on promoting spore germination rate. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2012.03.004
