Stressors and Agrofood Productivity


At the end of this course the student will have acquired knowledge, skills and competencies that enable him to develop the ability to interpret and analyze parameters associated with agro-food processes and apply concepts and techniques with ecophysiological impact for the development of methodologies for enhancing the production and conversion of agro-industries.

In this framework, the students will be able to dominate and exploit scientific bases that enable the evaluation of detailed aspects and skills with application in the development of plant productive capacity, integrating knowledge related to the radiation spectrum, water potential, thermal factors and indexes of inorganic and organic pollution.

Teaching method

The teaching, supported in the use of multimedia projections and e-learning methods (i.e., the use of the Moodle program), will include theoretical and practical classes grounded in the theoretical and application of concepts.

Evaluation method

Continuous assessment in two components: theoretical (2 individual Mini-Tests - each with 30% of the final classification) and theoretical-practical: (production and oral presentation of a research project on the synthesis and mobilization of assimilates and crop production, based on literature and laboratory studies - 40% of the final classification).

Final rating: (0.30*Mini-Test1) + (0.30*Mini-Test2) + (0.40*Research work). Approval requires a minimum score of 9.5 (scale of 20 values) for each component (theoretical-practical and theoretical).

Students without approval in the continuous assessment will be submitted to exam. Rating equal to 0.6*Exam+0.4*classification of theoretical-practical. Approval with a minimum grade of 9.5 (scale of 20 values).

Subject matter

Raw food of plant origin: food needs and agri-food intensification; Ecophysiology and agri-food production.
Ecophysiological evaluation linked to the productive plant capacity: photosynthetic active and ultraviolet radiation (anatomical changes; photoinhibitory mechanisms; tolerance mechanisms); limiting temperatures (interactions between plant species and heat stress, elevated temperatures - functional disorders and survival mechanisms; positive low temperatures - damage to sensitive species; freezing – damage mechanisms; water deficit (decrease cell turgidity; inhibition of metabolism of proteins and amino acids; stomatal closure and mobilization of assimilates; mechanisms of resistance, tolerance and senescence; considering climate change, combined CO2 and high temperatures); organic and inorganic pollutants (mechanisms and types, direct and indirect effects.
