摘要: 本实验选用白灵菇的三个不同菌株白灵pL03-7、白灵PN-1和白灵PN-9为实验材料,比较了三者菌丝生长速度、菌丝体生物量及多糖含量,并进行了菌株间的拮抗性测定。结果表明,三个菌株间存在明显的遗传差异。白灵pL03-7的菌丝生长速度最快,日均长速为7.35mm;白灵pL03-7的菌丝体生物量最高,为1.0612g/150ml。白灵pL03-7、白灵PN-1和白灵PN-9的菌丝体多糖含量分别为63.80、73.93和72.29μg/mg。

Abstract: The antagonistic effects, the growth speed of hypha and mycelial biomass as well as polysaccharide content of three different Pleutotus nerbrodensis strains were tested in this study. The results showed that the genetic diversity exists in three strains. The hypha growth speed of strain pL03-7 is the fastest, 7.35 mm per day. And strain pL03-7 has the highest mycelial biomass, 1.0612 g/150 ml. The polysaccharide contents of strains pL03-7, PN-1 and PN-9 are 63.80, 73.93 and 72.29μg/mg respectively.

Key words: Pleurotus nerbrodensis, growth speed of hypha, mycelial biomass, polysaccharide content, antagonistic effect
