多脂鳞伞紫外线诱变育种

摘要

Using an obtained Pholiota adipose strain as starting strain, spore suspension was induced by ultraviolet (UV). The results showed that a mutant strain UV-65 was obtained after 65s treatment under UV. It was demonstrated that UV-65 grew stronger than the starting strain and the production of mycelia increased by 20%. It had stable inheritance after six continuously passages.%该研究用已经选育出来的多脂鳞伞菌株作为出发菌株,利用紫外线对其孢子悬液进行诱变处理.结果表明,在紫外线照射65秒的情况下,得到一株正突变菌株(UV-65),经过斜面培养和发酵实验证实,其菌丝生长比出发菌株旺盛、菌丝产量提高20％；经过6代的连续传代培养,其遗传性状较为稳定.
