Many times the question arises as to which variety, treatment, nutrient regimen, etc. produces
the desired effects on the plant root system. Phenotype Screening Corporation's
Comparative Evaluation service can provide the answer in a quick and effective manner.
Our artificial growth substrate and our uniform, controlled Root Lab conditions provide the
perfect environment for that difference to manifest itself without random
weather, weed, pest, and soil condition effects.
Our evaluations may be used as a pre-screening step to generate a set of very high quality,
very detailed data using a small number of plants. Because of the nondestructive nature of our
imaging technology, the same individual plants can be followed over the time of the experiment.
If desired, above surface traits such as vegetative state and plant height can be recorded.
Other traits may be measured, if desired.
We describe below some of the applications we have performed using this technology.
Along with a description of the application, we provide example pricing for a typical
project. Please Contact us for a quotation for your project.
You may see differences in variety performance that cannot be understood or explained through
field trials or from an examination of excavated root systems. We can grow the varieties
in our Root Lab and show you the trajectory of root system development through the entire plant
growth cycle. If there is a morphological difference in varieties, we will show it to you.
The ultimate purpose of any treatment is to improve the input cost vs yield proposition.
In order to properly market and apply a treatment a certain level of understanding of how
the treatment works is necessary.
We can assist in the early phenomenology stage of evaluation by comparing treated vs untreated
plant development in our artificial substrate controlled environment. Besides root system
development over time, we can measure above surface properties over time and at end of
experiment. This can give insight as to the underlying mechanism of treatment effects.
The below animated bar chart shows growth of Maize roots for treated and untreated plants.
Each bar represents a root size class; note that size classes overlap as shown in the key on right.
Because the application of nutrient solution to plants grown in our artificial substrate is
controlled by programmable timers, the quantity of moisture available to the plant root system is
totally determined by experimental design. Because of the rapid draining of our growth substrate,
moisture conditions at the root can be changed more rapidly than would be possible in a nomal soil.
The evaluation of plants under nutrient stress is easy to do with our custom mixed nutrient solution
and totally inert artificial growth substrate. You specify the nutrient solution makeup and we apply
it to the plants. With our nondestructive imaging of the plant root system, measurement of
vegetative state, and end of experiment biomass, we can determine the
effects of nurient stress on plant development.
A minimal comparative analysis experiment is four sets of eight plants. This can be four comparisons for a
genetic evaluation or one control and three treatments, one set for each case.
Our current grow room capacity is 20 sets of eight plants in one meter deep containers.
Example pricing for four lines, or four conditions, eight plants each, is shown below.
Three levels of experimental effort and analysis work are priced. These prices are for corn, soybean,
or cotton in one meter deep containers. Other plants, container sizes, and experimental procedures are
