Differences in Root and Shoot Response to Limited N‐supply in Oat and Spring Barley

Differences in Root and Shoot Response to Limited N‐supply in Oat and Spring Barley Oat and spring barley cultivars, varying in origin and date of release, were examined in soil boxes with sloped glass‐face. Considerable genotypic differences were found in shoot and root response to high and low nitrogen supply. Oat cultivars, representing a wider germplasm collection, exhibited a stronger and partially different shoot and root response to applied N‐levels than barley cultivars. Cultivar‐fertilization interaction effects were significant for seminal and adventitious root variation. Genotypic specificity (plasticity) in root response, as revealed in some oat and barley cultivars with a deeper penetration and more vigorous root growth under the low N‐supply, was recognized to be a valuable adaptive characteristic for breeding plants on light‐textured soils. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Agronomy and Crop Science Wiley

Abstract

Oat and spring barley cultivars, varying in origin and date of release, were examined in soil boxes with sloped glass‐face. Considerable genotypic differences were found in shoot and root response to high and low nitrogen supply. Oat cultivars, representing a wider germplasm collection, exhibited a stronger and partially different shoot and root response to applied N‐levels than barley cultivars. Cultivar‐fertilization interaction effects were significant for seminal and adventitious root variation. Genotypic specificity (plasticity) in root response, as revealed in some oat and barley cultivars with a deeper penetration and more vigorous root growth under the low N‐supply, was recognized to be a valuable adaptive characteristic for breeding plants on light‐textured soils.
