SOME MORPHOLOGICAL CHARACTERISTICS AND PHENOLOGICAL STAGES OF CRATAEGUS MONOGYNA JACQ. VAR. MONOGYNA ACCORDING TO THE BBCH SCALE

Abstract

This study was performed to determine several morphological and phenological properties of the Crataegus monogyna Jacq. var. monogyna, which is naturally distributed in Atabey, a district rich in biodiversity. Morphological characteristics of leaves, such as size, breadth, stalk length, number of lobes and fruit size, diameter, and weight. Inflorescences have been measured in order to determine the morphological characteristics. Phenological growth stages were recorded by observations according to the Bundesanstalt, Bundessortenamt and Chemical Industries (BBCH) scale. Statistical analyses were performed with generalized linearized models using SPSS. When morphological characteristics were examined, the Atabey2 genotype could be considered as hopeful in terms of fruit weight, width and diameter. Determination of the stages of phenological development of Crataegus taxa, which has an important place as a non-wood forest product, according to the BBCH scale, has importance in terms of understanding the collection time of plant organs to be evaluated and supervising collection and sustainability. This study was the first one in which the BBCH scale was used in the analysis of the phenological development of the Crataegus monogyna Jacq. var. monogyna.
