| The life processes of the carrot plant were demonstrated by various parameters in this study. Growth processes, including photosynthesis, absorption of nitrogen and other nutrients and formation of cells, tissues and organs, are measured by the parameters weight of leaves and roots and emission 30-50 white of delayed luminescence. The nitrate content may indicate growth but has to be investigated further. Differentiation processes, including refining, ordering, ripening and secondary metabolisms, are measured by the parameters root stumpiness, saccharose, sweetness, dry matter and emission 30-50 ratio of delayed luminescence. Some other parameters may indicate differentiation processes but have to be further investigated: leaves/root weight ratio,... |

| We found clear correlations between management measures, tree characteristics and fruit characteristics. This means that growers can regulate apple quality during the growing season. On the basis of the two apple experiments, we can distinguish respective sets of growth and differentiation parameters and evaluate them in the light of conventional fruit cultivation science. Our results have little new value for fruit growing in practice, however. The value of our research lies in the approach developed to draw up a quality concept and the way in which we can apply this concept to crops about which little knowledge exists regarding the relationship between management measures, crop characteristics and product quality characteristics. Our research also offers... |

| In real life it is hard to distinguish between the two life processes, growth and differentiation. We cannot expect one measured parameter to represent only one aspect of vital quality. But for most parameters we can recognise emphases on one or more aspects of the vital quality concept. We made this prelimary classification both by thinking about the concept and by looking at the experimental results. Also the conventional parameters are interpreted as a result of these processes in a more holistic way than usual. We realise that various parameters all concerning the same aspect of our quality concept can show different levels of the aspect. To belong to the same aspect of the quality concept does not automatically mean that their correlation (see annex... |
