| Abstract:
For the first International Symposium on Apoplexy of Apricots and its control, held during XVI the International Horticultural Congress in Brussels, Belgium, 1962, on the my request was very king of Mrs E. Ulyatt, from Commonwealth Bureau of Horticulture and Plantation Crop and of Dr D. Jean Stamps (1962) from Commonwealth Mycological Institute. Great Britain to prepare the bibliography on Apoplexy and other Dieback diseases of apricots. This is based on material published since 1922 and abstracted in Review of Applied Mycology and Horticultural Abstracs. Thay was stated 126 references of various diseases and disorders affecting the main limbs or whole trees and usually terminating in the death of the tree are considered. These conditions, they say also, are often encountered in apricots growing in Europe, Africa, North America and Australia. In that time, the Symptoms of apoplexy or dieback vary greathy from region to region and this may help to explain the many names that have been used to describe disorders of this type. In Europe the most frequently used term for the premature death of apricot trees is apoplexy which is commonly applied to various diseases ascribed to a number of different factors. Other terms used in various countries include die-back, wilt, sour sap, black hearth, gummosis, decline, deperissement, Marillensterlen, heart failure. Similar to these, after ten years Mante and Blogid (1970) were registrated from the all over World 1.500 academic publications and with all others about 2.500 publications of which are 80% published in more than 460 periodicals. From these there a numerous publication relating to the problem of apricot apoplexy. Responsible for apoplexy or die-back can be broadly divided into 2 groups: 1. Physiological-rootstocks, soil and climatic factors, pruning and other cultural practices, and 2. Parasitic-bacteria, fungi, viruses and pest. So, we have started early in October 1961 in Perpignan, France and specially in Brussels, 1962 with wide range of the apricot problems. There were found different theoretical and practical views on apricot problems-apoplexy. They are quite understandable, if we bear in mind that each of these views has been hardened under different geografical ecological and agrotechnical conditions. It was a great importance that all attendance on the mentioned Symposium agreed that apricot problems should henceforth be approuched according to a more organized system and on an international level. | |
