AESTHETIC CHARACTERISTICS OF DECORATIVE PEAR SHAPES OF VNIISPK GENE POOL

Abstract

The results of the study of the aesthetic characteristics of 6 genotypes of decorative pear (17-43-30, 17-43-36, Alaya, Sharovidnaya, DK-2 and DK-3) are presented. The research was carried out at VNIISPK in 2012-2014, using a modern method for assessing the decorativeness of research objects. The most decorative for the sum of points was the DK-2 genotype, which received a score of 25 points. The Alaya variety was decorative at the average degree. Sharovidnaya, 17-43-30, 17-43-36, DK-3 were the least decorative. Some varieties, including those having a low total score, have one or several distinctive decorative features and can be successfully used in the landscape compositions in which these characters are important. The studied pear varieties in various degrees are characterized by valuable decorative qualities. Restrained growth peculiar for 2 genotypes (DK-2, Sharovidnaya). The spherical crown habitus is characteristic for 3 objects (17-43-30, 17-43-36, Sharovidnaya). DK-2 and DK-3 have a crown of a conical shape. A high intensity of flowering was observed in DK-2. Anthocyanin color of fruits is inherent in Alaya. Most of the studied varieties (17-43-30, 17-43-36, Sharovidnaya, DK-2, DK-3) retain ornamentality throughout the whole year. DK-2 can be the most attractive for landscaping purposes. It has the highest sum of decorativeness points and a set of morphological features valuable for the needs of landscape design and preserves the aesthetic appeal and originality of the appearance during the whole year.
