Sunfleck use research needs appropriate experimental leaves


Credit: CC0 Public Domain “All the roads of learning begin in the darkness and go out into the light.” This quote is often attributed to Hippocrates and exhibits a double level of relevance in photosynthesis research. The use of light by plant leaves to drive photosynthesis is often studied in steady state environments, but most plant leaves are required to adjust to fluctuations in incident light every day. The research into use of fluctuating light by plant leaves has expanded in recent decades. A study from the Western Pacific Tropical Research Center at the University of Guam has shown that accurate results in this subdiscipline of plant physiology can only be obtained when methods employ leaves that were grown in fluctuating light prior to experimental methods. The results have been published in a recent issue of the journal Plants .

The experimental results confirmed that leaves which were constructed under homogeneous shade such as commercial shade fabric did not respond to fluctuating light in a manner that was similar to leaves which were constructed under fluctuating light. To expand the applicability of the results, three model species were employed for this study. Soybean represented eudicot angiosperms, corn represented monocot angiosperms, […]
