研究了一株具有生防潜力的芦苇内生真菌Choiromyces aboriginum Mü1W1C6菌株的生物学特性。结果表明,与麦芽糖培养基、查彼培养基相比,该真菌在马铃薯葡萄糖琼脂培养基(PDA)和基本培养基上生长较好;在PDA培养基上1,0～35℃均能生长2,0～30℃时生长较好2,5℃时最适;葡萄糖、果糖能显著促进该真菌的生长,而乳糖、淀粉、麦芽糖则没有明显的促进作用;有机氮源更有利于菌丝生长,无机氮源不利于菌丝生长;该内生真菌对pH的适应范围很广,在pH 5～11的范围内都能生长良好,相比之下,在中性偏碱性的环境中生长最好;光周期、生长因子、微量元素对芦苇内生真菌的生长均无显著影响。
The biological characteristics of a strain of Choiromyces aboriginum Mü1W1C6 with endophytic potential of Phragmites communis were studied. The results showed that the fungi grew better on potato dextrose agar medium (PDA) and minimal medium than on maltose medium and petri dish, and grew well on PDA medium at 1,0 ~ 35 ℃ , And the best growth at 0 ~ 30 ℃ was at 2,5 ℃. Glucose and fructose could significantly promote the growth of the fungi, while lactose, starch and maltose had no obvious promoting effect; organic nitrogen source was more conducive to mycelial growth , Inorganic nitrogen source is not conducive to mycelial growth; the endophytic fungi adapt to a wide range of pH, good growth in the pH range of 5 to 11, in contrast, in a neutral alkaline environment The best; photoperiod, growth factors, trace elements have no significant effect on the growth of endophytic fungi Phragmites australis.
