Fruits in Slovenia (Cherry Blossom)

<b>Cherry Tree (Prunus Avium L.)</b><p>Cherries are one of the most popular and attractive fruit trees. In Slovenia the cultivation of cherries has a rich tradition. The leading cherry-producing regions are the Gorica region (the Vipava Valley and the Goriška Brda region) and the Slovene Istria, though cherries are also successfully produced in other fruit-growing parts of Slovenia. The cultivation of cherries for market began 140 years ago. At that time the towns on the territory of the present-day Slovenia were already linked by the southern railway (Vienna - Ljubljana - Trieste (1856), Gorica (1866)). The railway connection made brisk trading possible with other towns within the Austro-Hungarian Empire. From the Gorica region, which is today the most important cherry-producing region in Slovenia, cherries were successfully sold in Vienna, Prague and other European cities. Slovenia was an important cherry exporter even in the period between the wars. After the year 1950 the export sharply declined and since 1970 cherries have been cultivated only for the home market.<br>The cherry has beautiful medium-sized white blossoms. Blossoms are bisexual consisting of 5 petals and 5 sepals. The pistil is encircled by 15 to 30 stamens. The tree is self-sterile, which means that different cherry varieties blooming at the same time must be interplanted to provide compatible pollen for pollination. For effective pollination cherries require the presence of honeybees, which effect the pollination of most blossoms.<br> The European cherry fruit fly or cherry maggot (Rhagoletis cerasi L.) causes the greatest damage on medium late to late cherry varieties. Attacked fruit is wormy and inedible. The cherry fruit fly hatches in mid-May. The adult flies measure about 5 mm. The body is shinny black with yellow triangular shield at the end of thorax. The wings are transparent with prominent dark crossbands. The flies start to lay eggs when cherry fruits start to turn yellowish. The fly inserts eggs just beneath the skin of the fruit close to the stalk. Normally a single egg per fruit is inserted. The larvae feed on the pulp surrounding the kernel. When full grown, they leave the fruit, normally when the latter drops to the ground. The maggot burrows into the soil, where it pupates and hibernates.<br>The stamp depicts a new Slovenian sweet cherry variety - 'Vigred', produced by hybridization. The tree is medium vigorous, wide spreading with large leaves and blossoms. It blooms in the second or third group of cherry blossoming with the fruit ripening in the third cherry week. The fruit is of large size averaging 8.5 grams. The skin is glossy red to brown red. The flesh is firm, sweet and red in colour. It has a small stone and medium stalk. Vigred is medium susceptible to cracking.<p>Franci Štampar, Ph.D<br>
