RESOURCE POTENTIAL ASSESSMENT OF THE APRICOT IN THE NATURAL POPULATIONS OF DAGHESTAN
The resource assessment information for the yield of fruits and seeds of the natural apricot populations in the conditions of Intramountain Daghestan at different altitude levels has been obtained for the first time. It is determined that statistical methods are optimal for potential productivity accounting of the natural apricot populations. A comparative assessment of the resource potential of the natural apricot populations has been carried out with the use of the two accounting methods: 1 - based on the ratio of productivity per unit volume to the total volume of the crown; 2 - modular branch counting method. The methods have been tested in the two apricot cenopopulations - the Burtanimakhi village and the Kuli village, where a five-year-old branch is taken as the minimum accounting unit, the number of the sample trees - 30. It has been found that both methods are generally interchangeable; the differences between them in average values are not significant by the Student's t-test. It has been revealed that with a single repetition of the tree, both methods give a high scatter of values, and more significant when taking into account the number of modular branches, with a difference in the coefficient of variation up to 1.6 times. When comparing the resource potential of apricot populations at different altitude levels, it has been found that with altitude above sea level, the productivity of trees decreases, and in terms of 1 hectare by 7-8 times. The percentage of fresh weight of fruit pulp, endocarp and seed has been established to be 87/8,5/4,5%, respectively. In conditions favorable for the growth of apricot populations (700-1300 m above sea level), up to 3000 kg of dried apricots and 650 kg of dry seeds can be harvested from 1 hectare
