conidiospore

The pathogen source of inoculation is mainly from the conidiospore of infected tobacco plant residue the year before .

病菌的侵染来源主要是来自烟株病残体产生的分生孢子。

The lethal temperature of mycelium and conidiospore exceeded 50 ℃ 3 .

菌丝和分生孢子生命力顽强，致死温度均超过50℃。

The result of experiments on three kinds preserved condition showed the germination rate of conidiospore was 91.4 % in 4 ℃ refrigerator after 6 months .

3种储藏条件试验的结果，以4℃冰箱中黑暗下6个月的孢子萌发率最高（91.47%）。

In addition , conidiospore gemination rates were 0.00 % and 18.96 % respectively , compared with that of CK was 23.11 % .

与对照分生孢子23.11%的萌发率相比，10.00%浓度的薄荷提取液处理的萌发率为0.00%，20.00%的泽漆为18.96%。在抑制效果上，薄荷提取液显著优于泽漆提取液。

After being cultivated for about 6 days , two primary mycelia fused through terminal cells or other parts and developed into secondary mycelia with clamp connection and conidiospore .

培养约6天，两条初生菌丝通过顶端细胞或其他部位融合，发育成具有顶端分生孢子和锁状联合的次生菌丝体；

The optimum conditions for the conidiospore sprouting were 25-28 ℃ of the temperature and 100 % relative humidity , PH 6-7 was optimum for the sprouting and growth .

该菌分生孢子萌发适温25－28℃，相对湿度为100%，萌发和生长最适pH值为6－7。
