Correlations between plant temperature (Tp) in <i>Artemisia ordosica</i> and environmental factors.

N = 143. Tp0, Tp1/4, Tp1/2, Tp3/4, Tp1: Plant temperatures at fractions from the bottom of 0,1/4, 1/2, 3/4,1 of the total plant height; Ta: Air temperature; Tc: Air temperature in the crown; V: wind speed; S: solar radiation intensity; RH: Relative humidity; Hc: Relative humidity in the crown.
For all dates measurements were conductes over periods of up to 30 min and normalized before correlation analysis. Larger values indicate a stronger relationship with the corresponding index. Ta and Tc had larger values than Tp.
