| 摘 要： | 对金钗石斛黑斑病菌的生物学特性、培养性状及形态等研究表明,病原菌为细极链格孢菌(Al-ternaria tenuissima).适宜菌丝生长的温度为5~35℃,最适温度为25℃,分生孢子萌发的温度范围为5~35℃,最适温度为25℃.光照对菌丝生长和孢子萌发无明显的影响.药效试验表明:10%苯醚甲环唑67μg/mL,64%恶霜灵1 607μg/mL对菌丝的抑菌率均为100%,90%乙磷铝的抑菌效果不明显. |

| Abstract: | Biological characteristics of Alternaria tenuissima in Dendrobium nobile were studied.The results showed that the suitable temperature range for mycelid growth is from 5-35℃,and the optimium temperature is 25℃.The temperature is 5-35℃ to germinate of spores,and 25℃ were optimum.Different illumination did not obviously influence to mycelial growth and spores germination.The study also indicated that the fungicides(10% difenoconazole at 67μg/mL,and 64% oxadixyl at 1607μg/mL) creat strong fungistatic action against Alternaria tenuissima in vitro,and the percentage for fungistutic action of inhibiton to the mycelial growth recorded 100%.The fungicides(90% fosetyl-aluminium) is not obvious for fungistatic action. |
