摘要/Abstract

摘要： 为通过紫外诱变育种技术选育香菇耐高温新品种,以野生耐高温香菇品种XG-1为出发菌株,采用不同紫外照射时间和强度筛选耐高温香菇新品种,并对综合性状较好的诱变菌株进行栽培试验。结果显示:在诱变时间25~30 s,诱变强度为12~16 W时,筛选出诱变菌株XG-5,定名为金西1号;其出菇温度可达38 ℃,属耐高温品种;斜靠栽培每袋(规格17 cm×33 cm的聚乙烯袋)可产1.013 kg,生物转化率达92.09%。

关键词: 高温香菇, 紫外诱变, 诱变时间, 诱变温度, 生物转化率

Abstract: In order to breed new varieties of Lentinus edodes which can bear high temperature by UV mutation, a wild high temperature resistant L. edodes sample XG-1 was used as the starting strain. New varieties of high temperature resistant L. edodes were screened by different UV irradiation time and intensity, and the cultivated strains with better comprehensive characters were cultivated. Mutant XG-5, known as Jinxi 1 was screened when the mutation time was 25~30 s and mutation intensity was 12~16 W; Its fruited temperature was up to 38 ℃, so it belonged to high temperature resistant varieties. In leaning cultivation mode, the field of Jinxi 1 could reach 1.013 kg per bag (polyethylene bag size 17 cm × 33 cm), and the biotransformation rate reached 92.09%.

Key words: high temperature Lentinula edodes, UV mutagenesis, mutagenesis time, induced temperature, bioconversion rate
