Physical-chemical analyzes of standard pear cultivars grown in Turkey with Turkish varieties that were domesticated in Bosnia and Herzegovina

ABSTRACT: The assortment of pear in BiH is very diverse. A significant contribution to the cultivation of a large number of sorts and varieties of pears was contributed by the constant migration of people who carried and planted fruit trees with them. The largest number of fruit varieties and pears in BiH came from two directions. From the east with the Ottoman Empire and from the west with the arrival of the Austro-Hungarian Empire. The pear, as a fruit species, takes a significant place in fruit production, considering that it can be grown in a wide range of climatic conditions, different ripen times, from early summer to late autumn, and multi-purpose use.The fact is that many varieties of pears arrived from Turkey centuries ago and that they were preserved and retained in BiH. This fact is corroborated by the names of variety / Karamut, Jeribasma, Black Izmir and others The paper analyzes the following parameters: pH, total acidity in mmol / 100 g, pectic substance% Ca-pectinate, raw fiber (%), vitamin C in mg / 100 gr, natural invert (%), total invert (%), total phenols in mg / 100 g of fruit, soluble dry matter (° Brix).The aim of this paper is to determine the usable value and, therefore, the possibility of introducing standard cultivars grown in Turkey to our area through physical and chemical analysis of fruits of indigenous and standard pear trees. The juice of the tested variety has a lower pH value than the reference values. Low supply of Ca pectate. Vitamin C content is above average. The tested varieties in terms of soluble dry matter content meet the applicable legal framework
