| Abstract/Contents: | "The monitoring of chlorophyll fluorescence reactions has become a fundamental tool in turfgrass physiology research. Fluorescence signals are able to estimate non-photochemical quenching (NPQ), the maximum quantum yield of photosystem II (Fv/Fm), the apparent electron transport rate (ETR), and other useful parameters. These parameters are generally used to demonstrate tolerance or susceptibility to abiotic and biotic stress, but the most common instruments used may not be the most suitable for turfgrass measurements. Typical chlorophyll fluorometers consist of a fiber optic probe, with diameter of 1 cm or less, that is placed on the leaf surface for quantifying fluorescence reactions. However, the size and the shape of the fiber optic probe can limit accuracy when describing whole-leaf and/or whole-plant stress. Many times individual measurements on turfgrasses may represent fluorescence reactions from multiple leaves from different plants, and the acquired data can be highly variable. Here, we show that the use of chlorophyll fluorescence imaging (Heinz-Walz Instruments) can overcome the aforementioned challenges associated with measuring chlorophyll fluorescence reactions in turfgrasses by providing high-resolution maps on single leaves and across whole plants." |
