Selection studies on fig (Ficus carica L.) in Antalya Province of Turkey

Turkey is one of the gene centers of fig in the world and there are great  variations and distributions in wild fig forms as well as fig cultivars. The primary objective of this study is to select valuable fig genetic resources in Ibradi and Kumluca (Antalya) province and to conserve the promising figs genetic resources. Populations consisting of native fig genotypes were selected and chracterized in terms of pomological and morphological traits. The data revealed that some of the fruit and leaf characteristics of the investigated fig types were significantly different in terms of location and fig types. Consequently, it is suggested that these promising fig genetic resources could be used for further breeding programs and therefore they need to be preserved.Keywords: Ficus carica L., genetic resources, fruit characteristics, leaf characteristic

Some Physical and Chemical Properties of Two Jujube (Ziziphus jujuba Mill.) Genotypes Grown in Western Turkey

Ziziphus jujuba Mill. is widely distributed in tropical and subtropical Asia (Afghanistan, China, India, Iran, Pakistan, Turkey, South Korea, etc.), Europe (Greece, Italy, Russia, Spain, etc.), North America (USA, Canada) and Oceania (Australia). It is a nutritious fruit crop and is used fresh, dried and as a component in processed foods. This experiment was conducted to determine some physical (fruit weight, width and length, fruit shape index, fruit skin color, stone weight, width and length, flesh/stone ratio) and chemical (soluble solid contents, titratable acidity, vitamin C, sugar and organic acid profiles) properties of the fully ripened fruits of two jujube genotypes collected from Isparta-Sutculer flora ('Genotype-1') and Antalya-Gazipasa ('Genotype-2') regions of Turkey. Organic acids, sugar profiles and vitamin C were determined by high-performance liquid chromatography (HPLC). The fruits of 'Genotype-2' were significantly larger than those of 'Genotype-1'. The fruit weight of 'Genotype-2' was four times higher than 'Genotype-1'. Both genotypes differed from each other with respect to their chemical properties. 'Genotype-2's fruits had significantly higher total sugar content than those of 'Genotype-1'. The main sugars found in both were glucose and sucrose. Regarding organic acids, ascorbic and malic acids were the most prominent in the pulp. In general, the results demonstrated that two jujube genotypes varied in respect to their physical and chemical characteristics

Volatile compounds determined by HS/GC-MS technique in peel and pulp of fig (Ficus carica L.) cultivars grown in mediterranean region of turkey

Aromatic profile of peels and pulps of four commercial fig cultivars ('Bursa Siyahi', 'Karabakunya', 'Sari Lop' and 'Sultan Selim') from Turkey were determined first time by using Headspace Gas Chromatogropy-Mass Spectrophotometer (HS/GC-MS) technigue. In general, aldehydes and therpenes were the major volatile group responsible aroma for peels and pulps in fig fruits. Total aldehydes were higher in pulps than peel in all cultivars. However total therpenes were higher in peel rather than in pulp. Among therpenes, ß-caryophyllene were the major volatile compounds found in both peel and pulp. Phenol, 2,6-bis (1,1-dimethylethyl)-4-methyl were the second important group responsible for fig aroma presented in both peel and pulp. Among aldehydes, 2-hexanal were found in high proportion only in pulp in all cultivars. The other groups responsible fig aroma were 2-furancaboxaldehyde, 5 (hydroxymethyl), benzyaldethyde, furfural and Germacrene D. ?-curcumene, ß-bisabolene and ß-sesquiphellandrene were determined only in cv. 'Bursa Siyahi' peel and pulp and discriminated this cultivar from the others

Bioactive content of rose hips of different wildly grown rosa dumalis genotypes

A rose hip is the fruit of a rose plant and mostly belongs to Rosa canina and Rosa dumalis. These species are genuine found as wild in natural conditions, while in some countries are cultivated for their hips that are picked and used in a wide variety of preparations. Because they contain a variety of antioxidants, carotenoids, flavonoids, polyphenols, leucoanthocyanins and catechins, rose hips are considered to be a good cancer preventative. The Rosa genus has been the focus of many recent studies due to its potential benefic effects on treatment and prevention of several diseases. However, there are few in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine bioactive content, including ascorbic acid, total phenolics, total flavonoids, total carotenoids and antioxidant activity of Rosa dumalis genotypes growing wild in Erzurum province located eastern Anatolia. The results revealed that fruits of Rosa dumalis different genotypes were rich rich in terms of vitamin C, which ranged from 402 to 511 mg/100 g fresh weight base. The total phenolic content varied from 297 to 403 mg/100 g fresh weight. The genotype 'E-09' had the highest total flavonoids content (229 mg quercetin equivalent/100 g fresh weight) and the lowest value was attributed to genotype 'E-04' with 143 mg/ quercetin equivalent/100 g fresh weight. The antioxidant activity of the genotypes was between 12.9-28.6 ?g Trolox/ml samples. The results revealed that there was enough diversity among Rosa dumalis genotypes for bioactive content and promising genotypes, with high bioactive content, were determined, which can become study material for future breeding activities

Some physicochemical characteristics, bioactive content and antioxidant capacity of loquat (Eriobotrya japonica (Thunb.) Lindl.) fruits from Turkey

Overwhelming evidence from epidemiological, in vivo. in vitro, and clinical trial data indicates that a plant-based diet can reduce the risk of chronic diseases, particularly cancer. Some important physicochemical characteristics, bioactive content and antioxidant capacity of fruits of seven commercially grown loquat (Eriobotrya japonica (Thunb.) Lindl.) cultivars ('Akko XIII', 'Champagne de Grasse', 'Guzelyurt 6', 'Hafif Cukurgobek', 'KKTC 3', 'KKTC 4' and 'Sayda') harvested from Antalya province in Turkey were investigated. The results indicated cultivar-specific differences for most of the physicochemical characteristics, bioactive content and antioxidant capacity tested. Fruit mass and fruit flesh ratio ranged from 33.18 g ('Champagne de Grasse') to 61.38 g ('KKTC 3') and 80.44% ('Akko XIII') to 86.29% ('KKTC 3'). Total phenolic content varied from 140 ('Guzelyurt 6') to 253 mu g GAE per g ('Akko XIII'). The cultivar 'Champagne de Grasse' had the highest soluble solids content (14.58%). The highest total antioxidant capacity was observed in fruits of 'Akko XIII' with all three antioxidant-determining methods. There were close positive correlations between antioxidant capacity and total phenolic content in loquat fruits. Results show that the loquat represents a good source of biofunctional phytochemicals because of their high phenolic, carotenoid and antioxidant contents. (c) 2012 Elsevier B.V. All rights reserved
