MEDITERRANEAN FRUIT TREE CROPS

Academic Year 2026/2027 - Teacher: MARIO DI GUARDO

Expected Learning Outcomes

Course Description

The course provides students with an in-depth understanding of the interactions among biological, environmental, and technical–cultural factors involved in citrus, grapevine, and olive production. Particular attention is given to issues related to varietal selection and cultivation techniques, with a focus on identifying the most appropriate solutions for practical needs.

Learning Outcomes
By the end of the course, students will be able to:

Knowledge and understanding:

  • Analyze the relationships between biological, environmental, and cultivation factors in Mediterranean cropping systems

Applying knowledge and understanding:

  • Evaluate and select appropriate varieties for citrus, grapevine, and olive production.

  • Apply cultivation techniques suited to different environmental and production contexts.

  • Make independent agronomic decisions aimed at sustainability and product quality.

  • Provide technical support to stakeholders in the citrus, olive, and grapevine sectors regarding pre-planting choices and management practices

Making judgements:

  • Make independent agronomic decisions aimed at sustainability and product qualits

Communication skills:

  • Communicate technical and scientific information accurately, using appropriate terminology related to Mediterranean fruit tree crops and production systems.

  • Interpret and communicate information from scientific literature, technical reports, and experimental data related to fruit tree production.

  • Present and discuss technical topics concerning the biology, cultivation, management, and production of Mediterranean fruit tree species.

Learning skills:

  • Independently identify and critically evaluate scientific and technical sources concerning Mediterranean fruit tree species and their cultivation.

  • Acquire and update knowledge autonomously on emerging issues, technologies, and innovations in Mediterranean fruit production.

  • Use scientific literature and digital resources effectively to support independent learning and problem-solving.

Course Structure

Teaching Methods
Lectures supported by projected diagrams.

Other Activities
Practical exercises, discussion of case studies, and educational field visits.

Inclusion and Accessibility
To ensure equal opportunities and in compliance with current legislation, students may request a personal meeting to arrange possible compensatory and/or exemption measures, based on the learning objectives and their specific needs.
Students may also contact the designated CInAP (Center for Active and Participatory Inclusion – Services for Disabilities and/or Specific Learning Disorders) representatives of our Department: Prof.  Anna De Angelis.

If the course is delivered in blended or remote mode, appropriate adjustments may be made to the above, in order to ensure consistency with the syllabus


Required Prerequisites

A solid knowledge of fruitculture is important to better understand similarities and differences with respect to the species of the course. A basic knowledge of the fiosology and morphology of tree species is mandatory

Attendance of Lessons

Attending the classes is not mandatory, but strongly recommended, as it facilities the learning process and contributes to the achievement of the learning objectives.

Learning Assessment

Learning Assessment Procedures

Learning will be assessed through an oral examination. Student performance will be evaluated based on the following criteria:

  • Learning ability and depth of understanding of the topics covered

  • Clarity and coherence in synthesis and exposition

  • Reasoning and critical thinking skills

Grading Scale

  • Fail

    • Knowledge and understanding of the topic: significant shortcomings and inaccuracies 

    • Ability to analyze and synthesize: irrelevant with frequent generalizations 

    • Use of references: completely inappropriate.

  • 18–20 (Pass threshold)

    • Knowledge and understanding of the topic: very modest with evident imperfections

    • Analytical and synthesis skills: Barely sufficient.

    • Use of references: Barely appropriate.

  • 21–23 (Fair)

    • Knowledge and understanding of the topic: knowledge is slightly above the minimum acceptable level

    • Analytical and synthesis skills: a fair ability to analyze and synthesize information, presenting arguments in a logical and coherent manner

    • Use of references: Uses standard references.

  • 24–26 (Good)

    • Knowledge and understanding of the topic: Good knowledge.

    • Analytical and synthesis skills: good analytical and synthesis abilities, arguments are presented consistently

    • Use of references: Uses standard references.

  • 27–29 (Very Good)

    • Knowledge and understanding of the topic: More than good knowledge.

    • Analytical and synthesis skills: considerable abilities of analysis and synthesis

    • Use of references: the topic has been explored in depth
