An important part of plant science is understanding how plants respond to their environment, so monitoring plant phenotypes is of great importance. CD BioSciences can help customers around the world observe all aspects of plant performance, including size and shape, root structure, growth rate under specific conditions, and more. These data can be used to develop improved and sustainable crops.
Suitable for: Most crops and pasture types.
The photosynthetic machinery that enables plants to convert sunlight to chemical energy has two means of dissipating light energy that exceeds a leaf's needs: fluorescence, which is the instantaneous re-emission of light of another wavelength, and heat. Leaf fluorescence can also be actively stimulated with an external light source, and this has become a powerful technique for studying photosynthesis by individual leaves. An instrument at the APPFs CSIRO node is extending the approach to plant canopies by inducing fluorescence with an eye-safe laser.As the laser strikes a clump of leaves, light energy is absorbed by the pigment chlorophyll, and the amount of fluorescence is determined by both the amount of light absorbed and the amount not used in photosynthesis or released as heat.The laser is programmed to emit pulses of light in rapid succession, varied with pulses that are more spread out, and a detector continuously measures the amount of fluorescence occurring on the target leave
