Developing
Applications with Partners
We
develop the application to suit the needs of our partner. Below are
some applications developed in conjunction with our research partners.
Root System
Development
Example
images of a single maize plant taken approximately 12 days apart
beginning at four days following germination. this illustrates the
capability to nondestructively image the same plant at several points
in its development. This capability can drastically reduce the number
of plants required to do a development study. Red/cyan glasses are
required to see the stereo effect.
   
Characterize
Intragenic vs. Intergenic Structural Traits
In
the case of rice, two varieties can be compared by simply inspecting
the images. The below images show two plants each of two different
varieties. Red/cyan glasses are required to see the stereo effect.
 
 
Ra4993
relatively wide angular
distribution of root system
and relatively short, large
diameter roots |
Ra5531
relatively narrow angular
distribution of root system
and relatively long, fine
root structure |
Angular
distribution of roots would be completely lost using the conventional
wash and scan method.
Root System
Classification
The
distinctions between two different varieties may not be easy to see
using the unaided eye. Two varieties of soybean were distinguished by
plotting lateral root density against taproot length.
In
this case, the prolific root variety is above the center line and the
normal variety is below the center line. When the two varieties are
crossed, this classification capability will be used to screen progeny
for the prolific root characteristic.
Introduction of
Stressors
A
plant may be subjected to stress during part or all of its development.
The polymeric growth substrates used by Phenotype Screening Corporation
contain no nutrients, moisture, or pests of any kind. The Plant
Scientist has total control over nutrient and moisture delivery to the
plant. Pests may be introduced and plant response monitored.
When
subjected to iron deficiency Maize displays a chlorosis in the
interveinal areas.
A
soybean subjected to drought stress.
This
pest was found growing in the root system of a poplar cutting started
in our substrate material. It is believed to have hatched from an
insect egg previously deposited on the poplar cutting.
