Applied Plant Physiology-Plant Stress Identification

Content

THEORY 1. Identification of stresses in the field 2. Sequential steps to identify stresses at the crop level a. Knowledge of the characteristics of the cultivated plant b. Recognizing the symptoms and signs - determining the problem c. Observation of possible particular patterns in the field d. Review of crop history e. Distinguish between problems caused by biotic or abiotic stressors in the field e1. Distinguish between biotic stressors 1. Symptoms or signs of pathogen infestation 2. Symptoms or signs of insect, mite or herbivore infestation e2. Distinguish between abiotic stressors 1. Mechanical stress 2. Extreme values of physical parameters (temperature, light intensity, oxygen concentration, water sufficiency) 3. Toxicities 3. Identification of stresses at the plant level a. Seeds b. Seedlings c. Grown plants c1. leaves c2. shoots c3. roots 4. Difficult cases: Different stressors causing similar symptoms PRACTICAL EXERCISES IN THE FIELD Field training on the sequential steps to identify stresses at the crop level. Observation of possible particular patterns in the field. Differentiation of symptoms caused by biotic or abiotic stress factors in the field. Identification of stresses at plant level and its organs based on symptoms and signs. Learning to use a key.

Learning results

The course aims to synthesize all the knowledge that students have acquired in order to recognize the effects of stressors in the field. Upon successful completion of the course, students will possess knowledge regarding the steps to follow in order to identify biotic and abiotic stresses of individual plants or crops in the field or in the greenhouse.
