| Abstract:
Exposure of sweet peppers, eggplants and pod beans to stress temperature (0–3 °C) for a 10-day period determined surface pitting and depressions. On these areas epidermal and hypodermal cells were completely altered, plasmalemma and tonoplast were broken and the cellular content was electrondensified. Intensity of respiration, electrolyte leakage, tissue conductivity and dry matter were smaller in samples affected by chilling injury than those of samples exposed to 10 °C. The values of these indicators decreased but the acidity of cellular sap increased during the 10-day period of exposure to stress temperature. | |
