Abstract
The accurate and rapid measurement of physiological O2 transport is vital for understanding spatially and temporally dynamic metabolism and stress signalling in plant cells and tissues. Single channel luminescent O2- quenched optrodes have been available for use in laboratory and field experiments since the early 2000’s. However, to collect the large datasets needed to understand O2 transport in complex systems, many experiments require a multiple channel O2 sensor system. This research reports the development of a multiplexing fiber optic O2 microsensor system designed to conduct high temporal resolution experiments for field studies of plant physiology. The 10 channel system was demonstrated for measuring O2 concentration in developing soybean seeds (Glycine max L. Merr.) within a climate controlled greenhouse.
