耐低温灰树花工厂化生产菌株的筛选

Screening on Resistance of Grifola frondosa Production Strains at Low Temperature

[目的]筛选适合低温环境生产出菇的菌种。[方法]通过比较13个野生灰树花菌株的菌丝生长速率、生长势、拮抗性,并以栽培周期、子实体品质及前期生物学转化率等为指标进行工厂化栽培考察。[结果]菌株"ZDL-05"在(18±2)℃时68 d完成2次出菇,且生物转化率为82.3%,同时在颜色、风味、叶片厚度、口感及朵形等方面表现优秀,适合灰树花低温工厂化栽培。[结论]灰树花菌株ZDLM-05可以作为秋冬季或较低温地区工厂化生产菌种。

[Objective] In order to select the suitable low temperature environment to produce mushroom strains. [Method]The comparison of mycelium growth rate,growth vigor,antagonism,cultivation period,fruitbody quality and early biological conversion rate of 13 wild strains of Grifola frondosa as indicators of industrial cultivation were carried out. [Result]The results showed that： the growth temperature shelf culture mode strain‘ZDLM-05＇at（ 18 ± 2） ℃ for 68 days,two times the cumulative matrix fruiting biological transformation rate was 82. 3%,while at low temperature,flavor,taste and leaf thickness,shape was so excellent,and was suitable for low temperature Grifola frondosa factory cultivation. [Conclusion] Grifola frondosa ＂ ZDLM-05＂ was used as factory production strains at low temperature area.
