Climatic conditions and leaf-level responses across a natural drought and recovery. (A) An image of FIL2 (left) and HAL2 (right) that was taken prior to the onset of drought demonstrates the reduced growth rate of HAL2 compared to its lowland relative. From May 25 through July 5, 2013, <1 cm of rain fell at the site of the experiment. (B) Cumulative rainfall is presented along with daily maximum soil temperature. Leaf water potential (MPa, Ψ) was measured on July 5 (drought) and again on July 8 after irrigation and natural rainfall (recovery); means ± SE are presented for Ψ at predawn (C) and midday (D).
