DETERMINATION OF PHENOLOGICAL STAGES OF Malus kirgishorum APPLE SPECIES IN CENTRAL ANATOLIAN ECOLOGICAL CONDITIONS

Abstract

Many different fruit species can be grown in the Central Asian region due to topographic and ecological conditions. Among these species are some apple species native to this region. In this research, studies were carried out in order to reveal the phenological diversity of Malus kirgishorum, one of the species in Central Asia. Bud swelling, bud burst, half-inch green, pink bud, beginning of flowering, full flowering, end of flowering and leaf fall dates of 20 M. kirgishorum genotypes were determined in Central Anatolia ecological conditions. According to the results of the research, bud swell in genotypes took place on March 17 - April 8, bud burst on March 20 - April 12, half-inch green on March 26 - April 15. Flowering did not occur in 4 genotypes due to the young age of the trees. In the flowering genotypes, the beginning of flowering was between April 15-26 and the end of flowering was between April 28 and May 10. Leaf fall on the trees occurred between the first and last weeks of November. The findings can be used in apple breeding programs.
