GREENSTIM Helping the plants to overcome environmental stresses For production of open field vegetables and fruits Improves the crop performance under conditions of heat, cold, salinity and drought Increases the amount of phytomass, seed and fruit yield Widely tested on different crops under commercial cultivations Natural and environmentally safe product
GREENSTIM Mode of action Based on glycinebetaine which occurs naturally in many organisms Accumulates naturally in certain plants (e.g. sugarbeet, spinach) in response to cold, drought and salinity Penetrates through the plant surface and translocates throughout the plant within 24-hours Protects the plant cells against negative effects of environmental stresses

GREENSTIM Greenstim as an osmoprotectant Greenstim acts as an osmoprotectant in the plant cell Facilitates water uptake and retention Stabilizes enzymes and protects membranes Enhances photosynthesis, nitrogen metabolism and translocation during environmental stresses
GREENSTIM Effect of Greenstim in the plant cell I Less inhibitory to enzyme activity than equivalent concentrations of inorganic ions Protects root membranes against heat destabilization Protects thylakoids against freezing stress Protects against NaCl/KCl inhibition and heat denaturation of several plant enzymes
GREENSTIM Effect of Greenstim in the plant cell II Protects enzymes against inactivation in dilute solution Protects proteins against the unfavorable consequences of dehydration Protects the oxygen-evolving PSII against the inhibitory effects of NaCl by preventing salt-induced dissocation of proteins Increases the threshold temperature for inhibition of PSII-mediated electron transport of chloroplasts

GREENSTIM Abiotic environmental stresses Abiotic environmental stresses are important factors limiting crop productivity 1. Lack of water and salinity Affect around 40 % of the most productive areas Mediterranean basin, California, Southern Asia, Australia Plants are sensitive to Na, Cl, So 2 2. Low temperatures 3. High temperatures
GREENSTIM Water deficit stress Water deficit stress disturbs many plant growth processes: –Cell enlargement and reduces growth of leaves, stem cell wall synthesis and reproductive structures –Protein synthesis reduces enzyme activity –Stomatal opening reduces photosynthesis –Photosynthesis reduces growth
