Abstract

Data characterizing the temperature dependence of the growth and CO₂ emission of two species of xylotrophic fungi (D. confragosa and D. tricolor) during their development on wort–agar and wood debris in a laboratory experiment are presented. Currently available estimates of the temperature dynamics of CO₂ emission by wood debris do not fully take into account the relationship between temperature, CO₂ emission, growth, and respiratory activity of fungi. In the range of 10–30°C, both linear growth and CO₂ emission activity of fungal mycelium are positively and linearly related to temperature (Spearman’s correlation coefficient, 0.94–0.97) to the same extent (Q₁₀ of growth, 2.2; Q₁₀ of respiration, 2.1), and CO₂ emission is directly proportional to mycelium area and its specific emission activity. As a result, the temperature effect on CO₂ emission is a derivative of two equally temperature dependent factors: growth and specific emission activity of mycelium. It is equal to the product of the effects of each of the factors separately and is described by an exponential equation, which reflects the non-additive, possibly synergistic nature of the temperature enhancement of CO₂ emission in the range from 20 to 30°C.

温度对两种木质营养真菌和木屑二氧化碳排放的影响

摘要

本文介绍了实验室实验中两种木质营养真菌（D. confragosa和D. tricolor ）在麦芽汁琼脂和木材碎片上发育过程中生长和 CO ₂排放对温度的依赖性的数据。目前对木材碎片CO ₂排放温度动态的估计并未完全考虑温度、CO ₂排放、生长和真菌呼吸活动之间的关系。在10~30℃范围内，真菌菌丝体的线性生长和CO _{2排放活性均与温度呈相同程度的正线性关系（Spearman相关系数为0.94~0.97）（} Q₁₀的成长，2.2；呼吸作用的Q _10，2.1 )，CO ₂排放量与菌丝体面积及其比排放活性成正比。因此，温度对CO ₂排放的影响是两个同样与温度相关的因素的导数：菌丝体的生长和比排放活性。它等于各因素单独作用的乘积，用指数方程描述，反映了20～30℃范围内CO ₂排放温度升高的非加和性、可能的协同性。。
