Abstract

The berry mass of the blue honeysuckle plants of different environmental and geographical provenance was shown to be affected by the weather conditions at the time of the fruit setting and ripening. Pollination by defective pollen and by the pollen of closely-related species resulted in the decreased berry mass.

Highlights

The last decades have seen increased blue honeysuckle
The aim of the work was to study the variation of the fruit mass in samples of the three subspecies of Lonicera caerulea of different environmental and geographic provenance, as well as genetic origin, in relation to growing conditions and pollination modes
The berry mass and seed number were studied under self- and cross pollination of the three blue honeysuckle cultivars: L. caerulea subsp. altaica (Pall.) Gladkova

Summary

Introduction

The last decades have seen increased blue honeysuckle Family) cultivation in different countries with temperate climate. The berry of blue honeysuckle represents an aggregate fruit, in which two juicy ovaries with 10–15 seeds each are surrounded by juicy and fleshy outer layer. The latter by its surface properties and development determines berry form and mass of different blue honeysuckle samples. The berry yield is an important component of the plant production [2]. The berry mass is regarded as an important characteristic of elite forms or varieties to be considered when making decisions about the introduction into culture
