摘要

In all European regions, variations of temperature have a cyclic character with a relatively regular change for the periods of active vegetation and dormancy. The unfavorable combination of high temperatures and low rainfall, as well as temperature changes at the end of winter and the beginning of spring season are factors which may have critical effects upon the development of orchards. Also important factor often responsible for establishing the warm or cold winter margin for many fruit trees and which strongly affects production near those margins is the amount of chilling available during the plants rest phase of its growth cycle. Chilling is generally considered to be that amount of time during the period the plant is in rest when the temperature is below 0°C. Apricot trees is the most widely spread orchard in Bulgaria. They can grow in all over the country, but the optimum results are got only in separate regions, where the meteorological conditions are most suitable for their growth and development. The paper is aimed at establishing the empirical relation between the sums of negative temperatures measured in the period from of durable transitions of temperatures across 0°C (chilling degree days) and the number of days with temperature below 0°C and establishing empirical relation between date of durable transitions of temperatures across 10°C to fruits ripening and the number of days with temperature above 10°C.
