      abstract     = {Early vigor has been proposed as a favorable trait for
                      cereals grown in drought-prone environments. This research
                      aimed at characterizing early stage shoot and root growth of
                      three Spanish barley landraces compared with three modern
                      cultivars. Genotypes were grown in an automated phenotyping
                      platform, GrowScreen-Rhizo, under well-watered and drought
                      conditions. Seminal and lateral root length, root system
                      width and depth were recorded automatically during the
                      experiment. Drought induced greater growth reduction in
                      shoots $(43\%$ dry weight reduction) than in roots $(23\%$
                      dry weight). Genotypic differences were larger under no
                      stress, partly due to a more profuse growth of landraces in
                      this treatment. Accession SBCC146 was the most vigorous for
                      shoot growth, whereas SBCC073 diverted more assimilates to
                      root growth. Among cultivars, Cierzo was the most vigorous
                      one and Scarlett had the least root dry weight of all
                      genotypes, under both conditions. Root growth was redirected
                      to lateral roots when seminal roots could not progress
                      further in dry soil. This study reveals the presence of
                      genetic diversity in dynamics of early growth of barley. The
                      different patterns of growth observed for SBCC073 and
                      SBCC146 should be explored further, to test if they affect
                      field performance of barley in drought-prone environments},
