Fig. 4.

Short-term Q₁₀ values of Agrostis scabra and Agrostis stolonifera grown at soil temperatures of 17 °C and 27 °C for 7, 14, 21, or 28 d. Q₁₀ was calculated as the ratio of root respiration rate grown at 17 °C and measured at 27 °C to those grown and measured at 17 °C (27/17 °C) or the ratio for roots grown at 27 °C and measured at 37 °C d to those grown and measured at 27 °C (37/27 °C). Error bars represent standard errors (n=5).
