Combined impacts of prolonged drought and warming on plant size and foliar chemistry.

ABSTRACT:

Background and aims

Future shifts in precipitation regimes and temperature are expected to affect plant traits dramatically. To date, many studies have explored the effects of acute stresses, but few have investigated the consequences of prolonged shifts in climatic conditions on plant growth and chemistry.

Methods

Plant size and metabolite profiles were assessed on naturally occurring Plantago lanceolata plants growing under different precipitation (ambient, 50 % less than ambient = drought) and temperature (ambient, +0.8, +2.4 and +4.0 °C above ambient) treatments at the Boston Area Climate Experiment (constructed in 2007).

Key results

The analysis of primary and secondary metabolites revealed pronounced effects of drought, and a precipitation × temperature interact
