Phenological Development Stages and Effective Temperature Total Demand in Bursa Siyahı Fig Variety

Abstract

Temperature is one of the ecological factors limiting yield and quality in the care of the region where fig will be grown, as in many fruit species. The effective temperature total demand is one of the important parameters in determining the cultivation potential of a fruit species in any region. Temperature values are needed for the establishment of new orchards in the commercially important Bursa Siyahı fig variety. This study was carried out with the aim of determining the effective temperature total demand of Bursa Siyahı fig variety in Aydın conditions between the years 2019-2021. Although the sum of the effective temperature from bud burst to main crop ripening date on years, it was between 1314 oC-days, and the average of three years from bud bloom to leaf fall was 2506.18 oC-days. According to the BBCH scale, the main crop ripening date was 207 ± 2 days and 219 ± 2 days, although it varied between years. The total effective temperature during the harvest period was 1.040,07 oC-days, on average over three years. Optimum climate values should be taken into account in the garden facilities to be established in different regions with the table Bursa Siyahı fig variety, which has a high export value and economic importance.
