温度对蜡蚧轮枝菌MZ041024菌株菌落生长和产孢量的影响

Influence of Temperature on the Growth and Spore Production of Verticillium lecanii Viegas(MZ041024)

室内测定表明,蜡蚧轮枝菌MZ041024菌株菌丝和分生孢子在10-35℃均能生长,适合温度范围15-30℃,当温度在25℃时,第7d的菌落为2.477±0.084 cm,第14d为4.597±0.069 cm,第21d为6.789±0.073 cm;产孢量分别为1.676×10^8孢子/皿,4.283×10^9孢子/皿,7.062×10^8孢子/皿,说明25℃最适合蜡蚧轮枝菌MZ041024菌株生长.

The mycelial biolmass and production of conidia of Verticillium lecanii Viegas MZ041024 were studied different temperature. The result showed mycelium growth and conidiospore production occurred at 10to35℃. The suitable temperature were between 15 - 30℃ ,But 25℃ was optimum temperature for mycelium growth and conidium production. The mycelia biomass of Verticillium lecanii Vie- gas （MZ041024） was compazatively high at 25 ℃ after 7d, 14d and 21 d. These diameters of colonies reached 2.477 ± 0. 084cm, 4. 597± 0. 069cm and 6.789 ±0. 073cm. The conidia production reached 1. 676 ×10^8, 4. 283×10^9 and 7. 062 ×10^8condia/disn.
