These three major parameters characterizing expansion growth of primary roots can be analysed over several days with high spatial (20 mum) and temporal resolution (several minutes) as the camera follows the growing root by an image-controlled root tracking device. In combination with a rhizotron set up for hydroponic plant cultivation the impact of rapid changes of environmental factors can be assessed. First applications of this new system proved the absence of diurnal variation of root growth in Zea mays under constant temperature conditions. The distribution profile of relative elemental growth rate (REGR) showed two maxima under constant and varying growth conditions. Lateral oscillatory movements of growing root tips were present even under constant environmental conditions. Dynamic changes in velocity- and REGR-distribution within 1 h could be quantified after a step change in temperature from 21 degreesC to 26 degreesC. Most prominent growth responses were found in the zone of maximal root elongation. 000051536 536__ $$0G:(DE-Juel1)FUEK257$$2G:(DE-HGF)$$aChemie und Dynamik der Geo-Biosphäre$$cU01$$x0 000051536 588__ $$aDataset connected to Web of Science 000051536 650_7 $$2WoSType$$aJ 000051536 65320 $$2Author$$adiurnal course 000051536 65320 $$2Author$$akinematics 000051536 65320 $$2Author$$aoscillation 000051536 65320 $$2Author$$aroot growth 000051536 65320 $$2Author$$atemperature 000051536 65320 $$2Author$$aZea mays 000051536 7001_ $$0P:(DE-Juel1)VDB3187$$aSpies, H.$$b1$$uFZJ 000051536 7001_ $$0P:(DE-Juel1)VDB7943$$aTerjung, S.$$b2$$uFZJ 000051536 7001_ $$0P:(DE-Juel1)VDB7944$$aKuesters, R.$$b3$$uFZJ 000051536 7001_ $$0P:(DE-Juel1)VDB8902$$aKirchgeßner, N.$$b4$$uFZJ 000051536 7001_ $$0P:(DE-Juel1)129402$$aSchurr, U.$$b5$$uFZJ 000051536 773__ $$0PERI:(DE-600)1466717-4$$a10.1093/jexbot/53.369.689$$gVol. 53, p. 689 - 698$$p689 - 698$$q53<689 - 698$$tThe @journal of experimental botany$$v53$$x0022-0957$$y2002 000051536 909CO $$ooai:juser.fz-juelich.de:51536$$pVDB 000051536 9131_ $$0G:(DE-Juel1)FUEK257$$bEnvironment (Umwelt)$$kU01$$lChemie und Dynamik der Geo-Biosphäre$$vChemie und Dynamik der Geo-Biosphäre$$x0 000051536 9141_ $$y2002 000051536 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000051536 9201_ $$0I:(DE-Juel1)VDB49$$d31.12.2006$$gICG$$kICG-III$$lPhytosphäre$$x0 000051536 970__ $$aVDB:(DE-Juel1)8092 000051536 980__ $$aVDB 000051536 980__ $$aConvertedRecord 000051536 980__ $$ajournal 000051536 980__ $$aI:(DE-Juel1)IBG-2-20101118 000051536 980__ $$aUNRESTRICTED 000051536 981__ $$aI:(DE-Juel1)IBG-2-20101118 000051536 981__ $$aI:(DE-Juel1)ICG-3-20090406
