Chlorophyll Fluorescence to Assess Drought Performance
November 14, 2008| |
Scientists at the Australian National University (ANU) have developed a rapid, non-invasive technique to assess plant performance during drought. The technique measures chlorophyll fluorescence to determine how plants cope up with low-water conditions. A paper describing the method was published online ahead of print by Plant Methods.
The ANU researchers led by Barry Pogson found that found plants' viability during increasing water deficit could be measured and quantified by measuring changes to the maximum efficiency of photosystem II (Fv/Fm), and that this was easily measurable by chlorophyll fluorometry. The versatility of the technique was verified by comparing drought performance of several Arabidopsis ecotypes to a variety of mutants with altered drought tolerance or photosynthetic efficiency. The chlorophyll fluorescence technique might complement existing methods of evaluating drought performance while also increasing the number of tools available for assessment of other plant stresses.
