【摘要】 采用摇床转速和装液量来控制不同通气量,对西瓜枯萎病尖孢镰刀菌株X.1.7 030527 02进行培养,研究结果表明:当装液量相同时,尖孢镰刀菌孢子生长量随转速的增加而增加,而当转速<60r/min和>150r/min时,尖孢镰刀菌孢子生长量随装液量的变化差异不大,当转速90～120r/min时,尖孢镰刀菌孢子生长量随的装液量增加而减少.装液量越大,平均孢子萌发率越高,100mL/250mL装液量的平均孢子萌发率最高,比50mL/250mL和25mL/250mL分别高1.6%和4.05%.摇床转速对孢子萌发率表现在转速低孢子萌发率高的趋势.菌丝体生长量受通气量(装液量和转速)变化影响较小.更多还原

【Abstract】 Culturing experiments of Fusarium oxysporum Schl.f.sp.niveum X.1.7-030527-02 for the ventilation were carried out under the different liquid volumes and rotate speeds.The results showed the amount of spores produced was positively related to the different liquid volumes under the rotate speeds,in which the more spores were reproduced in the triangle bottle contained with 25 mL/250 mL medium than that with 50 mL/250 mL or 100 mL/250 mL,respectively.The geminating rate of a spore was negatively correlated to the ventilation with the liquid volumes and the rotating speed.But the growth of the fungus was not greatly affected by the ventilation.更多还原
