From: Response characteristics of highland barley under freeze-thaw, drought and artemisinin stresses
The effects of freeze-thaw, drought and artemisinin stress on the POD activity of highland barley. In Figures, T1 represents the temperature dropping to 10 °C after freeze-thaw for 2 h; T2 represents the temperature dropping to − 5 °C after freeze-thaw for 8 h; T3 represents the temperature rising back to 10 °C after freeze-thaw for 14 h
