【中文摘要】 本文研究了草菇厚垣孢子的萌发条件及对不良条件的抵抗力.试验结果表明,草菇厚垣孢子萌发最适温度为40℃,培养基PH为7,对培养基的营养状况无要求;草菇厚垣孢子与菌丝体均不耐干旱;菌丝体可耐45℃3d,但50℃处理24h便失活,而厚垣孢子可耐50℃处理24h.在4℃处理14d后,厚垣孢子的萌发率没有下降,而菌丝体完全失活,厚垣泡子耐酸能力比菌丝体强。
【英文摘要】 The germination conditions and the resistance to undesirable environment of Volvariella volvacea chlamydospore were studied in this paper. The result showed that the optimal temperature for chlamydospore germination was 40℃ and the optimal pH was 7, and that the germination of chlamydospore had no relation to medium nutrient. The mycelium and the chlamydospore were not tolerant of drought. It was proved that the mycelium could tolerate 45 ℃ for 3 days, but it lost vitality at 50℃ for 24 hours, that the chlamydospore kept high vitality after being treated at 50℃ for 24 hours, that the chlamydospore germination rate did not decrease after being treated at 4℃ for two weeks, but the mycelia total lost the vitality, and that the chlamydospore had stronger tolerance of acid treatment than the mycelia.
