    Evidence suggests that a diet high in fruits and vegetables may decrease the risk of chronic diseases, such as cardiovascular disease and cancer, and phytochemicals including phenolics, flavonoids and carotenoids from fruits and vegetables may play a key role in reducing chronic disease risk. Recent research has proven that sour cherry (Prunus cerasus L.) is a valuable natural source of some bioactive compounds important in human health preservation. In our work, we identified the total antioxidant activity, anthocyanine content and "antioxidant density" of sour cherry varieties named "Újfehértói fürtös", "Debreceni bőtermő", "Kántorjánosi" and "Érdi bőtermő" and those of the "Bosnyák" sour cherry clones. "Antioxidant density" is a biological value indicator obtained in a synthetic way, which indicates the antioxidant capacity of the particular food, e. g. fruit and vegetable, related to 1 Calorie.

    Our investigation was carried out in four mango rootstocks were namely Zebda, Socaria, 13/1 an 4/9. This study reviewed the effect of these rootstocks on growth behaviour of Keit mango variety as a scion grown on them. This evaluation and comparison included data on following aspects: the vegetative growth characters, root growth parameter, uptake of some macro nutrient and some organic substance. All results in this regard refer that the Socaria rootstock gave the highest values off all parameters so it is considered as a vigorous rootstocks, means that the trees on this rootstocks will reach to high size after short time. By contrast, Zebda rootstocks gave the lowest values in this concern and this will reflect on tree size on it. This means that the Zebda rootstocks will be useful in the system of high density orchard comparing with Socaria. Concerning to other rootstocks, they were intermediate between Socaria and Zebda rootstocks.
