Introduction: Arabidopsis thaliana is a small plant member of the mustard (Brassicaceae) family, used as a model organism in plant biology. The balance between vital-metabolic processes of growth and development performed on living organisms, is often affected by external influences. These influences represented by temperature, humidity, light intensity and nutrients, stimulate, accelerate, slow down or even stop all qualitative and quantitative development of the plant.

Aims: To observe the evolution of plant in all phenological stages, starting with germination and ending with seed growth and development under the action of AD type bio-phyto-dynamic modulators. After the full growth of plant the research continues pursuing the possible changes relating to the plant genome.

Materials and methods: Seeds of Arabidopsis thaliana were used, divided in three variants. Two with DEA and DIEE AD type bio-phyto-dynamic modulators attached and the third representing the witness variant. After the basal wheel of leaves has been formed some plants were selected to be exposed to water stress.

Results: After a period of thirteen days without water the differences between the two categories were noticeable. The presence of bio-phyto-dynamic modulators managed to restore the balance needed to make visible the processes of growth and development of plants affected by water shortages.

Conclusion: The presence of AD type bio-phyto-modulators had a protective effect for the plants affected by water stress, acting as a protective shield against water shortage.
