Abstract in another language

Mucilage is receiving increasing attention because of its putative effects on plant growth,but so far no method is available to measure its spatial distribution in the rhizosphere.Wetested whether the C-H signal related to mucilage fatty acids is detectable by infraredspectroscopy and if this method can be used to determine the spatial distribution ofmucilage in the rhizosphere. Maize plants were grown in rhizoboxes filled with soil free oforganic matter. Infrared measurements were carried out along transects perpendicularas well as axially to the root channels. The perpendicular gradients of the C-H proportionsshowed a decrease of C-H with increasing distance: 0.8mm apart from the root centerthe C-H signals achieved a level near zero. The measured concentrations of mucilagewere comparable with results obtained in previous studies, which encourages the use ofinfrared spectroscopy to quantitatively image mucilage in the rhizosphere.
