Abstract
In greenhouse production systems often crop growth monitoring involving accurate quantification of plant physiological properties. plant becomes stressed when any biological or environmental factor inhibit growth and development. Stressed plants express their symptoms in many ways. It is difficult to detect and rapid accurate quantification of early symptoms with conventional measurement methods. The use of infrared thermography for detailed and continuous monitoring showed its ability to distinguish and show the thermal stress of plants under nitrogen deficiency and irrigation water, and to distinguish the percentages of plant contamination with heavy elements and their impact on vegetative characteristics, and to reduce the heat stress of plants using wax and water under protected greenhouse conditions in Libya.
