Researchers (IMAGE) American Society of Agronomy Caption Researchers Glyn Bengough and Nico Koebernick sampling a field experiment planted with barley that has different root hair properties: (i) parent wildtype, (ii) no root hairs, (iii) short root hairs, (iv) long root hairs and (v) a commercial variety with a very fibrous and hairy root system. Intact samples are being collected for XRay CT imaging so that the effect of root hairs on soil pore structure can be explored. Credit Paul Hallett. Usage Restrictions Please use with story only.
