2 ROOT DEVELOPMENT STIMULATOR MECHANISM BY WHICH AUXINS (IAA*) ARE PROTECTED KINETICS OF AUXIN DETERIORATION DIAGRAM OF THE MECHANISM OF AUXIN PROTECTION Intensity of auxin deterioration (Optical density) Average speed 2,73 nmole of IAA/min Average speed 1,07 nmole of AIA/min Phase of protection of auxins overtime Phase of kinetic protection Time peroxidase peroxidase + Ref. : Montpellier University Research Laboratory (34) *IAA : Indole-3-acetic acid REMARK In the presence of the enzyme peroxidase, the auxins are rapidly broken down in the control batch. The addition of root development stimulator into the reactive environment acts in two stages: protects the auxins from enzyme deterioration = protective phase over time significantly slows the speed of enzyme deterioration = kinetic protective phase, the speed with which the auxins deteriorate is reduced by 60%

3 ROOTS RESISTANCE PROCESSUS OF PLANT DEFENCES DIAGRAM OF THE MECHANISM OF ROOT DAMAGE Stress and intoxication, pathogens Tissue degradation Cytoplasmic imbalance (ionic : K/Ca, etc ) Production of isoperoxydases The lignification process scarring (protective barrier) Changes in isoperoxydasic activity in the ionic parietal extract in the presence or absence of Osiryl Isoperoxydasic activity (optical density) h 24 h 48 h 72 h 96 h Time ZOOM got a better isoperoxydasic rate = Eliciting parietal isoperoxydasic effect Ref. : Montpellier University Research Laboratory (34)

Drip feed application, sprinkling and watering at 0.2% concentration ( 0.5 % maximum watering concentration on vine plants). GENERAL RECOMMENDATIONS is preferably applied at the end of the watering cycle to prevent leaching.
