Tiefenverteilung von Wurzeln bei Winterweizen

Summary in the original language of the document

The production and distribution of roots was examined for two winter wheat cultivars
(Capo and Saturnus). Plants were grown in PVC tubes of 150 cm length that were
placed in a field. The length of roots in 20 cm soil sections was measured at three
times. Mean root length densities decreased from 7-15 cm cm-3 soil in the top 20 cm
soil to 2 cm cm-3 at soil depths below 80 cm. Only slight differences were obtained for
the two cultivars and between harvests. Saturnus produced relatively greater root
lengths in upper soil horizons, while Capo spread its roots further down the soil profile.
Maximum rooting depth was between 150 to 160 cm.
