The fig (Ficus carica L.) is one of the oldest fruit trees cultivated in Tunisia. Djebba region is located in the northwest of Tunisia. It is very famous by fig culture. Many specific fig genotypes are very appreciated locally and nationally. Taking into account these considerations, Djebba fig cultivars are subject of label products, namely, “Djebba figs.” This study was focused on fig germplasm characterization of 17 cultivars in Djebba region based on morphological and pomological traits. Results revealed a large variability within the local fig germplasms. The comprehensive analyses of all the data permitted to distinguish some particular genotypes as distinct cultivars, and groups of cultivars as polyclone varieties. It was possible to discriminate six distinct cultivars and two groups of multiclone varieties (Soltani and Thgagli) with different degrees of polymorphism. Hypotheses of homonymy and synonymy were suggested for some cultivars. The diversity is currently threatened by genetic erosion. Measure of conservation is necessary to be undertaken.

Ficus carica L. is one of the famous fruit trees from ancient times, which is grown all over the world. The wild fig plants are found from the Mediterranean to the Northwestern India. It is widely cultivated in the subtropical area such as the Mediterranean countries, Iran, Arabia, China, Japan, the USA (California) and Chile. The territory of Daghestan is the Northern border of distribution of the fig. This paper presents the ecological conditions of growing the fig populations in Daghestan. The results show large variability in the growing conditions of the fig plants in all the studied natural habitats. In five areas where the species F. carica L. grow in Daghestan, the plants show high intraspecific variability – the habitual polymorphism. Taking into account the fact that the fig in this region is located on the Northern border of its distribution and the fact that it is listed in the Red Book of Daghestan, the study of this species is of great scientific and practical interest.

The Common

Ficus carica (2n = 26) is one of the oldest fruit trees of the Mediterranean basin. Recently there has been increasing interest in this species, in particular for questions related to germplasm such as genetic diversity and cultivar identification. This study was undertaken to gain more knowledge of F. carica cytogenetics and provide data useful for the characterization of its germplasm. Karyomorphological analysis and physical mapping of 18S–25S and 5S rRNA genes by the FISH technique contributed to defining the basic traits of the chromosome complement of F. carica. However, the most interesting result was the discovery of triploid (2n = 39) cytotypes of the cultivated common fig. This result demonstrates the importance of cytogenetic investigations in studies of fig germplasm and emphasizes the role of cross-fertilization as a source of variability not only in wild populations but also in cultivated forms. The results of pollen analysis suggest spontaneous sexual polyploidization as a possible origin of triploid cytotypes. Further studies are necessary to clarify the origin and effective spreading of polyploidy, the presence of other ploidy levels, and their distribution in wild and cultivated forms.

Fruitlet Abscission

In mango (Mangifera indica L.), fruitlet abscission limits productivity. The INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) peptide acts as a key component controlling abscission events in Arabidopsis. IDA-like peptides may assume similar roles in fruit trees. In this study, we isolated two mango IDA-like encoding-genes, MiIDA1 and MiIDA2. We used mango fruitlet-bearing explants and fruitlet-bearing trees, in which fruitlets abscission was induced using ethephon. We monitored the expression profiles of the two MiIDA-like genes in control and treated fruitlet abscission zones (AZs). In both systems, qRT-PCR showed that, within 24 h, both MiIDA-like genes were induced by ethephon, and that changes in their expression profiles were associated with upregulation of different ethylene signaling-related and cell-wall modifying genes. Furthermore, ectopic expression of both genes in Arabidopsis promoted floral-organ abscission, and was accompanied by an early increase in the cytosolic pH of floral AZ cells—a phenomenon known to be linked with abscission, and by activation of cell separation in vestigial AZs. Finally, overexpression of both genes in an Atida mutant restored its abscission ability. Our results suggest roles for MiIDA1 and MiIDA2 in affecting mango fruitlet abscission. Based on our results, we propose new possible modes of action for IDA-like proteins in regulating organ abscission.

Taxonomic Characterization

New research has stimulated a large reevaluation of species with regards to the use of fruits from native plants. Araçá (a small Brazilian guava-like fruit) is found scattered in the wild in Pernambuco/Brazil. There is a scarcity of detailed studies on such regional fruit trees, especially the Psidium araçá Raddi species, whereas there is an enormous possibility to explore the potential offered by these fruits, such as in the field of gastronomy, where the search for new ingredients and exotic flavors associated with functional properties has been increasing. This article aimed to evaluate the physical, physicochemical, and taxonomic characterization of araçá obtained from different agricultural regions of Pernambuco in order to investigate the possibility of developing new products from this native fruit. The taxonomic identification confirmed that all collected material belonged to the species P. araçá Raddi. The average weight of 7.45 g/fruit was observed. With respect to pH, values between 3.17 and 3.48 were found, and the acidity as a percentage of citric acid was on the order of 0.96% to 0.99%. It was shown that the P. araçá Raddi fruit has a desirable quality for the food industry, presenting excellent conditions for the development of formulations of high commercial value and promising application in the national gastronomy.

The purpose of this study was to characterize cultivated genotypes of three jabuticaba species (Plinia cauliflora, P. trunciflora, and P. jaboticaba). Phenology and fruit growth, as well as leaf, flower and fruit traits were evaluated. Variability in all traits was observed among genotypes of the three jabuticaba species. The trait peduncle size is indicated for differentiation of the three species under study. The leaf and fruit sizes of the genotypes P. trunciflora 3, P. trunciflora 4, P. trunciflora 5 and P. jaboticaba 1 differ from those described in the literature for these species, indicating the formation of ecotypes. Jabuticaba fruit skin contains high anthocyanin and flavonoid concentrations, with potential use in food and pharmaceutical industries.
