Recent LI-6800 Publication

The “High mesophyll conductance in the high-yielding rice cultivar Takanari quantified with the combined gas exchange and chlorophyll fluorescence measurements under free-air CO₂ enrichment" study aimed to understand and define the ecophysiological traits that allow the high yield rice cultivar, Takanari, to support a high rate of photosynthesis.

Using the LI-6800, the study was able to quantify high mesophyll conductance (g_m) to determine to what extent gm influences photosynthesis. The study found that a high rate of photosynthesis in Takanari was supported primarily by greater stomatal conductance at the panicle initiation stage and by g_m at the grain filling stage.

LI-6800 One-Sided Leaf Gas Exchange

The new One-Sided Leaf Measurement kit (9968-313) allows users to explore gas exchange by looking at stomatal density or stomatal ratio on one side of the leaf. Dr. Paul Nabity at the University of California-Riverside, is using the kit to look at the formation of stomates and changes in stomatal density on the adaxial surface of grapes from phylloxera, a gall-forming, aphid-like parasite. The feeding and induced stomata formation helps promote assimilation of carbon into the gall.
