中文摘要：本文研究了在七种不同的温度条件（5-35°C）及8种不同的温度×CO2浓度组合(14-30°C 和775-870或1550-1650 mg/m3)条件下人工接种到菠菜上的疣孢漆斑菌的行为。结果表明气候条件与大环单端孢霉烯产生之间可能呈正相关。但是，因为疣孢漆斑菌产生霉菌毒素的能力，温度上升会诱导疣孢漆斑菌在温带地区传播；因而这种病原菌可能在将来很重要。
外文摘要：The behavior of Myrothecium verrucaria, artificially inoculated on spinach, was studied under seven different temperature conditions (from 5 to 35 °C) and under eight different combinations of temperature and CO2 concentration (14-30 °C and 775-870 or 1550-1650 mg/m3). The isolate used for this study was growing well on spinach, and the mycotoxins verrucarin A and roridin E were produced under all tested temperature and CO2 conditions. The maximum levels of verrucarin A (18.59 ng/g) and roridin E (49.62 ng/g) were found at a temperature of 26-30 °C and a CO2 level of 1550-1650 mg/m3. Rises in temperature as well as in temperature and CO2 concentrations had a significant effect by increasing Myrothecium leaf spots on spinach. The biosynthesis of verrucarin A was significantly increased at the highest temperature (35 °C), while roridin E was influenced by the CO2 concentration. These results show that a positive correlation between climate condition and macrocyclic trichothecene production is possible. However, because of the ability of M. verrucaria to produce mycotoxins, an increase in temperature could induce the spread of M. verrucaria in temperate regions; this pathogen may gain importance in the future.
