Yield components and quality parameters at the date of harvest are the key areas of interest in preharvest investigations. However, after harvest, these charac-teristics change depending on both the initial state at harvest and the post-harvest conditions, such as air temperature, air humidity, and flow conditions close to the produce. Internal degradation processes as well as water loss as a result of transpi-ration lead to quality loss of horticultural produce in the postharvest chain, rapidly affecting the produce’s marketability. The aim of the present study was the evalua-tion of the effects of different preharvest conditions on postharvest behaviour of to-mato fruits. Tomatoes were grown at low or high air temperatures with either low or high nutrient solution concentrations and then subjected to different post-harvest conditions. We observed that low nutrient solution concentration negatively affected keeping quality, and in addition, a low air temperature during fruit growth intensi-fied this trend.
