Was ist ein Monitoring-PAM-Sensor? Ein Blick auf die Photosynthese selbst
Der PAM (Pulse Amplitude Modulation) Chlorophyll-Fluoreszenz-Sensor ist ein fortschrittlicher pflanzenphysiologischer Sensor, der direkt misst, wie effizient die Photosynthese arbeitet in der Pflanze.
Nicht indirekt wie der NDVI, sondern er misst die Photosynthese selbst.
Wie funktioniert er?
Der Sensor verwendet drei Hauptlichtkomponenten:
1. Gepulstes Anregungslicht (Pulsed Excitation Light)
- Er sendet kurze, kontrollierte Lichtpulse an das Blatt.
2. Chlorophyll- Fluoreszenz (Pulsed Chlorophyll Fluorescence)
- Das Chlorophyll reagiert auf diese Anregung durch Aussenden von Fluoreszenzlicht.
- Dieses Signal wird gemessen.
3. Umgebungs- licht (Ambient Light)
- Messungen können sogar bei Sonnenlicht durchgeführt werden.
- Dank der PAM-Technik wird es vom Umgebungslicht getrennt.
Was misst er?
Gemessene Basisparameter
Der PAM-Sensor liefert die folgenden kritischen Photosyntheseparameter.
- F₀: Minimale Fluoreszenz
- Fₘ: Maximale Fluoreszenz
- Fᵥ/Fₘ: Photosystem II (PSII) maximale Quantenausbeute

, began during the COVID-19 pandemic. The researchers had to conduct online meetings and field studies with strict disease control measures.
The eight research projects are:
1. The “Social Enterprise to Enhance the Grassroots Economy and Develop Sustainable Quality of Life for People in Bueng Kan Province” project by Asst. Prof. Dr. Natthaphon Panyaso, Faculty of Management Science, Loei Rajabhat University.
2. The “Development of Community Enterprise Groups into Social Enterprises to Strengthen the Grassroots Economy in Nong Bua Lamphu Province” project by Asst. Prof. Somchai Phimolsombat, Faculty of Management Science, Loei Rajabhat University.
3. The “Development of High-Value Communities and Social Enterprises to Create Sustainable Income and Quality of Life for Villagers in Nong Khai Province” project by Dr. Noppadon Phuchada, Faculty of Liberal Arts and Management Sciences, Kasetsart University Sakhon Nakhon Province Campus.
4. The “Mechanisms and Tools for Upgrading Community Enterprises to Social Enterprises for Community-Based Tourism in Loei Province” project by Asst. Prof. Dr. Anyamas Panyasit, Faculty of Management Science, Loei Rajabhat University.
5. The “Development of Social Enterprises to Enhance Potential and Add Value in the Agricultural Industry in Udon Thani Province” project by Asst. Prof. Dr. Sanchai Chotchuang, Faculty of Management Science, Udon Thani Rajabhat University.
6. The “Development of Social Enterprises to Create Sustainability for Communities in Sakon Nakhon Province” project by Asst. Prof. Dr. Tanaphol Petchraks, Faculty of Management Science, Sakon Nakhon Rajabhat University.
7. The “Development of the Grassroots Economy through Social Enterprises to Create Sustainability in Nakhon Phanom Province” project by Asst. Prof. Dr. Kanya Kantasiriphong, Faculty of Management Science and Information Technology, Nakhon Phanom University.
8. The “Development of Social Enterprises to Enhance Potential and Competitiveness of Community Enterprises in Mukdahan Province” project by Dr. Thananan Sripadung, Faculty of Liberal Arts and Management Sciences, Kasetsart University Sakon Nakhon Province Campus.
According to Dr. Chatchai, although the eight projects are now completed, the research team continues to provide ongoing support and advice to the local communities. This ensures that the social enterprises continue to grow and benefit the people in the Upper Northeastern Region 1 and 2.
The success of these projects demonstrates the potential of social enterprises to drive sustainable development and improve the quality of life for people in rural Thailand. By empowering local communities and fostering entrepreneurship, these initiatives are contributing to a more resilient and prosperous future for the region. (PRD)
