Assessing Drought Tolerance

Botanists are increasingly engaged in efforts to cultivate plants that have low water requirements. Measurement of chlorophyll fluorescence is an effective way of determining how well plants can cope with low-water conditions. The technique allows a quantitative and precise determination of viability in intact, drought-stressed plants.

Due to the increasing demands of industrial, municipal and agricultural consumption on dwindling water supplies, botanists are increasingly engaged in efforts to cultivate plants that have low water requirements. Barry Pogson led a team of researchers from the Australian National University who investigated whether chlorophyll fluorescence could be used in the assessment of plant water status during such studies.
