PEG treatment is unsuitable to study root related traits as it alters root anatomy in barley (Hordeum vulgare L.).

Abstract excerpt

BACKGROUND: The frequency and severity of abiotic stress events, especially drought, are increasing due to climate change. The plant root is the most important organ for water uptake and the first to be affected by water limitation. It is therefore becoming increasingly important to include root traits in studies on drought stress tolerance. However, phenotyping under field conditions remains a challenging task....
