Advantage in Knowledge

Digital plant phenotyping and digital seed testing provide advantage in knowledge.

Claiming such, we would like to point out the advantages by comparing the digital methods to non-digital phenotyping and seed testing. The non-digital methods are “traditional” measurements, assessments, or inspections where operators rate the sample material and note down their observations.

Of course, we would never presume that the esteemed experimenters would work careless, but it is general consent in human biology that errors occur unconsciously and fatigue comes with increasing working time, even if we try to work as accurate as possible.

data acquisition qualitydepend on current mood of inspectorstandardised
comparability: time to time or location to locationlow due to human factorhigh due to standardised technical settings
data transfererror-prone due to human writing or typingreliable due to automatic transfer into database

Thus, digital technology is a tool to assist the experimenter and to take over the boring and fatiguing part of the work.

The main advantage is that digital tools give access to a much broader range of data types and allow higher temporal and spatial density of data points.
