Abstract
Currently the biostimulant activity on plants of a substance is determined in laboratory via bioassays.
These methods are based on simple physiological responses that allow a comparison of the inducing potential of chemical substances (i.e., hormones) with molecules of proven biostimulant activity.
Examples of bioassays tests include the measurement of inhibition of watercress root or chicory hypocotyledon growth.
By comparing the effect of the examined substance with reference hormones possible biostimulant activities can be inferred.
One limitation of these bioassays is that the type of application, the dose, or the timing of the application of the biostimulant are not taken into consideration.
On the other hand, experiments carried out on whole plants concentrate on end points, detecting only the biostimulant effect at the end of growth, for example the biomass production.
A large gap in knowledge for the biostimulant effect still exists, environmental variability is not taken into account and large differences between the laboratory and field tests may exaggerate or hide the real biostimulant effect.
