abstract = {Drought tolerance is a complex phenomenon comprising many
physiological, biochemical and morphological changes at both
aerial and below ground levels. We aim to reveal changes on
root morphology that promote drought tolerance in oat in
both seedling and adult plants. To this aim, we employed two
oat genotypes, previously characterized as susceptible and
tolerant to drought. Root phenotyping was carried out on
young plants grown either in pots or in rhizotrons under
controlled environments, and on adult plants grown in big
containers under field conditions. Overall, the tolerant
genotype showed an increased root length, branching rate,
root surface, and length of fine roots, while coarse to fine
ratio decreased as compared with the susceptible genotype.
We also observed a high and significant correlation between
various morphological root traits within and between
experiments, identifying several of them as appropriate
markers to identify drought tolerant oat genotypes.
Stimulation of fine root growth was one of the most
prominent responses to cope with gradual soil water
depletion, in both seedlings and adult plants. Although
seedling experiments did not exactly match the response of
adult plants, they were similarly informative for
discriminating between tolerant and susceptible genotypes.
This might contribute to easier and faster phenotyping of
large amount of plants.},
