The study of ornamental features of feijoa (<i>Acca sellowiana</i> (O.Berg) Burret) in the conditions of Abkhazia

Abstract

The results of assessing the decorative features of the feijoa (Acca sellowiana (O.Berg) Burret) culture in the conditions of the Republic of Abkhazia. A. sellowiana has a high nutritional, medicinal and decorative value. A. sellowiana culture is promising for growing on agricultural lands. The objects of research are species plants of F A. sellowiana of seed origin. The yield and sanitary condition of A. sellowiana plants in 2022 are worse than in 2021 due to heavy spring rainfall. Data on the crown architectonics, flowering duration, fruit ornamentality, and leaf roundness index are presented. The most valuable feature is the architectonics of the crown of plants, the least valuable feature is the fruit characteristics (shape, size, evenness). All studied A. sellowiana plants have a semi-bush form with a wide spreading crown. Most of the studied A. sellowiana plants (11 pcs.) had a height of 4.6 to 5,1 m. Most of the studied A. sellowiana plants by the duration of flowering in 2021 (16 pcs.) and in 2022 (14 pcs.) is in the range of 27-28 days, while the 4 samples in 2021 and 1 sample in 2022 had a longest flowering (31-32 days). A scoring system for the characteristics of A. sellowiana is been developed taking into account the conversion coefficient. A. sellowiana plants № 2 and № 25 have the highest indicators for decorative traits (87 points each) and are promising for further study.
