Description
MICROCLIMATT aims to test the effectiveness of microalgae biostimulants, through demonstrative trials (phenotypic, physiological and transcriptomic), in the fight against the effects of climate change on wheat and tomato.
Objectives
- Development of microalgae derivatives with biostimulant activity for plant crops
- Evaluation of the effects of microalgae derivatives on gene expression using transcriptomic techniques.
- Verification of the effectiveness of derivatives to improve drought resistance in tomato and wheat crops
- Evaluation of the effects on productivity and CO2 fixation by plant biomass, resulting from the treatment of crops with microalgae derivatives
- Greenhouse and field verification of the influence of two microalgae-derived biostimulants on soil health supporting tomato and wheat crops
Results
- Industrial-scale development of the biostimulants BIO-1 and BIO-2 from microalgae cultures.
- Rapid and sustained overexpression of hundreds of genes related to the response to phytohormones, activating the plant's adaptation to different abiotic stresses (temperature, drought, salinity, osmotic pressure)
- Clear superiority of treated plants in recovering from the effects of water stress.
- Increased grain productivity in wheat crops on plots treated with BIO-1, representing more than 0.5 tonnes/ha of additional CO2 fixation. In greenhouse tomato crops, the additional CO2 fixation induced by the biostimulant reaches values of more than 1.2 tonnes/ha of additional CO2 fixation.
- In wheat crops, BIO-1 has a positive impact on the quality, functionality, and sustainability of the soils they support, promoting the mobility of important nutrients and increasing the structural biodiversity of the microbiota. A similar response to BIO-1 has not been observed in tomato crops.
