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

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
