Abstract
Detection of stressful situations of plants and crops presents a seductive possibility to discover harmful circumstances before a permanent damage or losses of harvest appear.
For this aim, a new portable ethylene measurement device was tested in a small glass chamber setup.
Hybrids of Solenostemon scutellarioides were stressed by high salt concentrations applied with the nutrient solution and by injury of upper parts.
Sample air was taken in the root zone.
During salt stress a change of the normal periodic rhythm of the ethylene synthesis was noticed on all stressed plants.
No reaction in ethylene synthesis was noticed in the root zone after injury stress.
