Stress responses on quality parameters of vegetable crops

Vegetable crops can be exposed to stress in the field by insect pests, pathogens, drought, high or low temperature, UV-light, mechanical stress from hail as well as by post-harvest handling or changes in atmosphere in storage rooms or packaging. Form another perspective ‘controlled stress exposure’ of plants by elicitor treatments can be used to improve the content or composition of chemical components. This is relevant for increasing content of biochemical with purposes related to human health or plants resistance to pests and environmental stress.
