| Aim(s) of Course |
: |
This course aims to enable the students to quantify the main water properties and flow processes within the soil-plant-atmosphere continuum and to familiarize them with some of the tools necessary to measure plant water relations parameters in the field; to provide the student with required background in evapotranspiration and photosynthesis mechanisms as well as drought and salinity tolerances of plants. |
|
| Course Contents |
: |
Chemical properties of water, soil texture and structure, soil and plant water contents and relations, evapotranspiration and water use efficiency, effects of abiotic stresses on plant growth and yield and aproaches to improve water productivity and stress tolerance of plants. Emphasis will be on water potential measurements with Scholander pressure chambers, leaf gas exchange measurements with porometers and photosynthesis systems. |
