M.A. Lisavenko Scientific Research Institute of Horticulture of Siberia (“SRIHS”) actively
conducts research and selection of blue honeysuckle (Lonicera caerulea L.). The selection is
based on purposeful hybridization of genetically different samples, with the aim to create
highly productive varieties. Honeysuckle forms such as L. altaica Pall., L. kamtschatica Pojark.,
L. edulis Turcz. ex Freyn, L. turczaninovii Pojark. and others are involved in the hybridization.
It is well-known that species and subspecies of honeysuckle differ significantly in the content
of basic chemical compounds in their fruits.
The present research studies the content of nutritive and biologically active substances
in the cultivars and hybrids of honeysuckle of SRIHS in the Forest-Steppe zone of the Altai
Region. The aim of the research is to determine the sources of the high content of nutritive
and biologically active substances, to select the parent varieties for purposeful cross-breeding
and, as a result, to create highly valuable cultivars.
The research object is fresh ripe fruits of local (selected by SRIHS) and introduced
honeysuckle cultivars and hybrids. The content of the following chemical compounds is
measured: soluble dry substances (SDS) (refractometric method), soluble sugars (direct
titration of aqueous extracts), organic acids (titration of extracts with 0.1 H alkaline solution),
ascorbic acid (vitamin C) (indophenol and potentiometric titration), pectin substances
(titrimetric method), bioflavonoids (spectrophotometric and colorimetric methods).
The research concludes that in the Altai Region the fruits of honeysuckle contain 9–17 %
of SDS, 6–12 % of sugars, 1–5 % of organic acids, and the sugar-acid ratio is between 1.5 and 9
relative units. Fruits of the following cultivars and hybrids have a high content of SDS (more
than 14%) and sugars (more than 10%): Selena, Assol, Ognenniy Opal, Berel, Barkhat,
Narimskaya, Andarma, 2-5-33, 3-303-82, 19-34-94, 19-83-94, 19-34-94, 20-70-94, etc. The
content of vitamin C in the fruits can reach 50 mg/100g (cultivars Zolushka, Gerda, Ognenniy
Opal, Assol, Berel, some hybrids). The content of pectin is between 0.1–0.9 %, the content of
pectin substances is between 0.4–1.9 %. In this regard, the best cultivars and hybrids are
Barkhat, Zolushka, Ognenniy Opal, Berel, 20-96-94, 21-76-94, etc. The content of
bioflavonoids varies between 800–2300 mg/100g. The cultivars Berel, Bakcharskiy Velikan,
Kasmala, Kalipso, Selena, Yumis, hybrids 36-23-07, 36-1-07, 4-21-09, 2-36-08, etc. are the
most valuable in this regard (1500 mg/100g and more).
The research also concludes that the varieties of honeysuckle L. kamtschatica are the
biggest source of high content of nutritive substances; the best sources of biologically active
compounds are the varieties of honeysuckle L. altaica.
Keywords: honeysuckle, fruits, biochemical composition.
