Grow Leaf Length
Gathering of data:
Attachment of thread on tip of a young growing leaf, thread over a wheel connected to rotary potentiometer and fixed with a weight.
Recording of changes in voltage via rotary potentiometer.
Calculation of leaf length growth via recorded voltage changes.
Leaf length growth of Arabidopsis thalianan in continuous light, plants transferred from 12h day-night regime to constant light in constant temperature.Grey box indicated darkness for 12h before change to constant light.
Example for results from Poire et al., 2010 Journal of Experimental Botany, Page 1 of 9 doi:10.1093/jxb/erq049
