- Leaf Porometer for stomatal conductance
The SC-1'sgets accurate stomatal conductance measurements practical for everyday research. It leaves the environment alone, and instead determines stomatal conductance by measuring the actual vapor flux from the leaf through the stomates and out to the environment.
- Leaf area meters
Several leaf area meters are available:
The ADC AM350 Portable leaf area meter is a compact, user friendly, field portable instrument for the accurate non-destructive measurement of leaf area and associated parameters. The AM350 consists of a high resolution scanner and scanboard with integral data and image storage. A multi positional carrying handle is provided for ease of use and increased portability. Measurements of leaves can be made on the scanboard plate or on an independent plain surface.E. Prikaziuk (Egor)PhD Candidate
The LI-3000C combines an easy-to-use readout console with the proven scanning technology of the LI-3000C sensor head to provide a powerful system for portable, non-destructive leaf area measurements. It utilizes an electronic method of rectangular approximation to provide 1 mm2 resolution. Leaf area, leaf length, average width, and maximum width are logged by the readout console as the scanning head is drawn over a leaf. Files can be viewed on the display or output to a computer using the LI‑3000C application software.
The LI-3100C Area Meter is designed for efficient, exacting measurements of both large and small objects. User-selectable area resolution of either 1 mm2 or 0.1 mm2 is available without having to change optics. This versatility provides the flexibility necessary for diverse project requirements.
- Plant canopy analyzers
Multiple versions of plant canopy analyzers are in the lab:
Leaf Area Index (LAI) measurements, such as those taken by the LAI-2000 or the LAI-2200/C, can be used to determine treatment effects, crop progression, and seasonal variation, to name a few parameters.
The process of obtaining LAI measurements can be very simple. To generate a value for LAI, take a series of Above and Below canopy readings, repeating as many times as needed to develop statistical robustness. The process of interpreting them, however, can be more complex.
