Nekužová, Daniela
This bachelor thesis is focusing on the evaluation of physical and chemical properties of tomatoes in the ripening and maturation period. In the theoretical part are mentioned information about origin and extension of tomatoes, botanical characteristics, described growing technology, the characteristics of the tomatoes during ripening, harvesting and storage, material composition and specification of measured values. Practical part is divided in two parts. Assessment of material composition and determination of gaseous components emanated from the tomatoes into the environment. The determination was made for these varieties: Hardy, Orkádo, Pálava and Sonet. Determination of material composition are weight, proportions, coat firmness, refraction and titrating acidity. Determination of gaseous components emanated from the tomatoes during ripening, harvesting and storage are determination of ethylene production and intensity of respiration tomatoes.
