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 Structure of the betaine molecule Osmolyte H H C H 3 methyl groups H H C + N H O H C H - C O H C H H Molecular weight 117,15 GREENSTIM Greenstim production Process steps: Sugar beet • Water extraction • Juice purification Beet sugar factory • Concentration • Crystallization Sugar Pulp Molasses betaine 3-6 % Process steps: • Filtration Separation • Chromatographic separation • Concentration Sugar Sep. molasses Greenstim • Crystallization 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 Hyperosmotic stress and no compensatory mechanisms Water flows out of the cell Increased electrolyte concentration in the cell Lower electrolyte concentration Depressed metabolism Water flows out of the cell Cell shrinks Water no longer flows out of the cell Electrolyte GREENSTIM Hyperosmotic stress and compensation with K+-uptake K+ water Increased electrolyte concentration in the cell Water balance maintained Cell volume maintained High energy cost K+ K+ Depressed metabolism GREENSTIM Hyperosmotic stress and compensation with glycinebetaine Glycinebetaine H HCH H HC H Water balance maintained N + H C H HCH H K+ O C - O Stable electrolyte concentration in the cell K+ Cell volume maintained Lower energy cost Stable metabolism Glycinebetaine GREENSTIM Greenstim as an osmoprotectant Osmotic stress Water no Greenstim Greenstim Water Increased salt levels Salts Turgor pressure negative Turgor pressure positive Metabolic rate reduced Metabolic rate normal GREENSTIM Betaine - methyl donor Cysteine Important functions: • DNA/RNA synthesis • secondary metabolites Me-transferases Methyl group Betaine Homocysteine CH3 *SAM methionine ATP *S-adenosyl methionine Protein synthesis 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, So2 2. Low temperatures 3. High temperatures GREENSTIM Water deficit stress • Water deficit stress disturbs many plant growth processes: – Cell enlargement and cell wall synthesis reduces growth of leaves, stem – Protein synthesis reduces enzyme activity – Stomatal opening reduces photosynthesis – Photosynthesis reduces growth and reproductive structures GREENSTIM Relationship between photosynthesis in leaf water potential (trendsetting) 35 30 60 Translocation 25 Photosynthesis 50 20 40 15 30 Translocation rate (% C removed from treated area h -1 Photosynthesis rate (mg CO2 fixed dm -2 h-1 70 10 -15 -17 -19 -21 -23 -25 -27 Leaf water potential (bars) Photosynthesis Translocation GREENSTIM Greenstim improves the fruit retention under environmental stresses DROUGHT, SALINITY, HEAT, FROST GREENSTIM STRONG NO GREENSTIM SUGAR SUPPLY WEAK GREENSTIM Storage and package size • Storage in room temperature and protected from humidity • In an unopened package the self life of the product is 2 years • Package sizes 2 kg, 25 kg and big bag (600-800 kg) GREENSTIM
