Abstract

The morphological characteristics of fruits and leaves of ten Greek Strawberry tree (Arbutus andrachne L.) genotypes located on the middle course, from the left side of Konjska River, in South part of Republic of Macedonia are investigated. Among the investigated characteristics of Greek Strawberry tree genotypes it is noted a large level of polymorphism. The genotype 2 is characterized with twice as big fruit mass (1.87 g) as most of other investigated genotypes. The genotypes 2, 7 and 9 are included in the group with large fruits. According to CIELab color system the fruit skin of genotype 2 is characterized with unusually dark red coloration (L* 21.02; a* 18.8; b* 12.0), while the most attractive are the fruits from the genotype 9 (L* 23.9; a* 28.3; b* 17.4). The investigated genotypes show differences in the fruit anatomy, especially the genotype 7 which is characterized with significantly higher value for lobedness degree, pericarp area and pericarp thickness, percent of pulp and number of seeds in fruit. Large differences in the leaves dimension and form are also determined.

Highlights

Greek Strawberry tree (Arbutus andrachne L.) is a member of Ericaceae family and it is an evergreen, bushy shrub or a small tree up to 12 m, which grows along the Mediterranean coast spontaneously, separately or in associationReceived 18 October 2017 Accepted 30 October 2017Acta Agriculturae Serbica, Vol XXII, 44(2017); 193-206 with the related species Arbutus unedo L. (Strawberry tree)
The parameters used in the analysis include fruit heigth (FH), fruit width (FW), mass of fruits (FM), leaf area (LA), leaf perimeter (LP), leaf length (LL), leaf width (LW), mass of leaf (LM) and mass of leaf petiole (Lpe)
The genotypes 4 and 7 are exception, and they have the greater width than height of the fruit (Table 1)

Summary

Introduction

Greek Strawberry tree (Arbutus andrachne L.) is a member of Ericaceae family and it is an evergreen, bushy shrub or a small tree up to 12 m, which grows along the Mediterranean coast spontaneously, separately or in associationReceived 18 October 2017 Accepted 30 October 2017Acta Agriculturae Serbica, Vol XXII, 44(2017); 193-206 with the related species Arbutus unedo L. (Strawberry tree). Greek Strawberry tree (Arbutus andrachne L.) is a member of Ericaceae family and it is an evergreen, bushy shrub or a small tree up to 12 m, which grows along the Mediterranean coast spontaneously, separately or in association. It is an evergreen small tree, widely distributed from the East Mediterranean to Northern Black Sea area (Bertsouklis and Papafotiou, 2009). Unlike the A. unedo which is more prevalent, Greek Strawberry tree is present mostly along the coast of East Mediterranean, and as more tolerant to low winter temperatures, it penetrates trough river valley and gorges deeper into mainland. In that kind location this fruit species is founded, in purified composition through harsh winter weather conditions, with absence of related and tenderer A. unedo on the territory of Republic of Macedonia, or in river gorges of the two west tributaries of the river Vardar. One location is extent the lower course of Crna River, and the other is the middle course of Konjska River (Em et al, 1974)
