Abstract

The aim of this study was to determine morphometric parameters of fruits within some genotypes of Elaeagnus multiflora Thunb., which are growing in the Forest-Steppe of Ukraine in M.M. Gryshko National Botanical Garden of NAS of Ukraine (NBG). Their morphometric parameters were following: fruit weight from 0.32 to 1.89 g, fruit length from 7.60 to 19.54 mm, fruit diameter from 4.39 to 10.32 mm, seed weight from 0.10 to 0.41 g, seed length from 7.40 to 13.30 mm, seed diameter from 1.34 to 5.07 mm. The shape indexes of fruits and seeds were found ranging from 1.25 to 1.56 and from 2.90 to 4.04, respectively. The analysis of coefficient of variation showed the difference of variability in morphometric characteristics between Elaeagnus multiflora samples. Data showed that the most variability of important selection characteristics is the average cumulative seeds weight - from 18.72 to 36.61%, seeds diameter - from 10.46 to 24.29%, fruits weight - from 9.15 to 22.24%. The other characteristics are more or less stable. Collected quantitative data were subjected to principal hierarchical cluster analysis. The cluster analysis of morphometric parameters exhibited that the Elaeagnus multiflora genotypes fell into two clusters. These cluster analysis results suggest that broad morphologic diversity was found in Elaeagnus multiflora genotypes examined in this study. The introduction population of the Elaeagnus multiflora, was created in the M.M. Gryshko National Botanical Garden in Kyiv, has a sufficient potential for successful selection work. These preliminary results could open the interest of farmers in this Elaeagnus multiflora and will be precedent for future domestication and introduction of the species in the agroproductive system in Ukraine and the rest of the world.

Evaluating of 10 genotypes of Elaeagnus multiflora determined the weight of the fruits in the range from 0.32 to 1.89 g, fruit length from 7.60 to 19.54 mm, fruit diameter from 4.39 to 10.32 mm, seed weight from 0.10 to 0.41 g, seed length from 7.40 to 13.30 mm, seed diameter from 1.34 to 5.07 mm

Summary

Introduction

Species of the genus Elaeagnus L. belong to the family Elaeagnaceae Juss. Elaeagnus multiflora Thunb. (cherry elaeagnus, cherry silverberry, goumi, gumi) has long been grown in China, Korea, and Japan a has for centuries been cultured as a decorative as well as for food and medicinal plant (You et al, 1994). (cherry elaeagnus, cherry silverberry, goumi, gumi) has long been grown in China, Korea, and Japan a has for centuries been cultured as a decorative as well as for food and medicinal plant (You et al, 1994). This species is known in Chinese traditional medicine (Sakamura and Suga, 1987), where some diseases such as a cough, foul sours, diarrhoea, itch and cancer have been treated for a long time (Lee et al, 2007). The content of citric acid was the highest among organic acids (Hong et al, 2006a)
