| 摘 要： | 主要研究绿粘帚霉厚垣孢子的诱导因素及其生物学特性。营养条件和生态因子试验表明,PD为绿粘帚霉产厚垣孢子的最佳培养基,厚垣孢子产生的最适培养条件为:光照、振荡、pH 3、30℃,在此条件下可完全抑制其分生孢子的产生,并在1周内可产生厚垣孢子8.00×106个/mL;厚垣孢子萌发试验显示,25℃、pH为6~8为绿粘帚霉厚垣孢子的最佳萌发条件,48 h时可达90%以上的萌发率,在5℃下贮存比较适宜。

| Abstract: | Factors influencing chlamydospore production of Gliocladium virens and characteristic of the spore are studied.The optimal medium for chlamydospore production of G.virens is potato-dextrose liquid which is screened out from 8 kinds of mediums.In PD medium,the optimum culture conditions are pH 3,30?℃,rotating in the light.The acid environment greatly enhances chlamydospore formation and inhibited production of conidia entirely,and the numbers of chlamydospore production are 8.00×10~6?chlamydospores/mL in these conditions for a week;Studies of chlamydospore germinating show: The optimum germination pH value was pH 6～8 and the optimum temperature of germination is 25?℃;the germinating rate can reach above 90% after 48 hours;the optimal temperature for storing is under 5?℃. |
