Abstract

Berry fruit species are, in many countries, considered biologically and economically valuable and important species of small fruits. The aim of this work was to examine the influence of either decreased or increased mesos concentrations (MgSO4, CaCl2, and KH2PO4) on shoot multiplication of five cultivars of three small fruit species (Amelanchier alnifolia var. cusickii, Rubus fruticosus ‘Black Satin’ and ‘Loch Ness’, and Vaccinium corymbosum ‘Brigitta Blue’ and ‘Toro’). Mesos nutrients were manipulated from half to four times their base concentration. The results indicate that mesos manipulation significantly influences the number and length of shoots in most of the studied cultivars. The greatest multiplication rate for A. alnifolia was achieved with tripled mesos, whereas ‘Black Satin’ and ‘Loch Ness’ reacted positively to a lower (1–2x) concentration of mesos. Decreasing the concentration of mesos to half led to worse quality in both blackberry and Saskatoon shoots. ‘Brigitta Blue’ was more sensitive to greater mesos concentrations compared to ‘Toro’. Optimizing the mineral nutrition of plants cultivated in vitro enhances their multiplication rate and contributes to a higher production of good quality plantlets.

Summary

Introduction

Known as berry crops, are small to moderate-sized fruits produced on perennial herbs, vines, or shrubs. Brambles (blackberry, raspberry and their hybrids), Ribes (currant and gooseberry), strawberries, table and winegrapes (Vitis spp.), and Vaccinium species (blueberry, cranberry, lingonberry, and others) are among the important small fruit crops worldwide [1,2]. Other small fruit species cultivated regionally include Amelanchier (serviceberry or Saskatoon), Sambucus (elderberries), and Viburnum (highbush cranberry or American cranberry bush). The importance of small fruits in horticulture lies in their dual role in the landscape and as food. The fruits themselves are highly prized for their varying shapes, textures, flavors, and colors [1]. Nutritious small fruits are a major human dietary source of phytochemicals including flavonoids and other phenolic compounds, cyanogenic glucosides, phytoestrogens [3], and phenols that are potentially health-promoting and are thought to fight against diseases [4]
