Pomegranate is one of the most important ancient fruit in Turkey where planting of pomegranate has increased rapidly in recent years. This study described desirable pomological and chemical traits of seventeen pomegranate genotypes selected from Narlidere district (Bitlis) in between 2010–2011 years. We found considerable variation on fruit weight, aril weight, fruit length and fruit width that important for pomegranate breeding ranged from 99.77 (N-15) to 515.97 g (N-05), 14.16 (N-01) to 41.92 g (N-10), 51.03 (N-15) to 90.99 mm (N-05) and 58.99 (N-03) to 103.11 mm (N-05) among genotypes, respectively. Chemical parameters are also considerable varied among genotypes and Soluble solid content (SSC), titratable acidity (TA), pH and juice yield of genotypes varied between 5.96 (N-02) to 9.13% (N-03), 0.12 (N-12) to 0.91% (N-14), 2.51 (N-14) to 4.52 (N-10) and 48.58 (N-06) to72.07% (N-01), respectively. Many genotypes were found to be promising both fresh consumption and processing. Promising genotypes indicate it’s importance as genetic resources and they have potential for future use in pomegranate breeding activities.
There is inadequate information in the case of rootstock application in pomegra­nate. In this study, propagation of pomegranate was investigated using bench grafting. The experiment was conducted as factorial in the framework of CRD design with three replications. The rootstocks were Rb R2 and R3 and the scions included 'Gorj-e- Dadashi' (Si) and 'Gorj-e-Shahvar' (S2). At the end of experiment, successful callus formation at graft union, bud take percentage (BT), bud take stem length, internodes length and shoot fresh and dry weight were measured. The results indicated that roots- tock influenced all measured characters including bud take and consequently the highest and lowest BT were obtained in Ri and R3, respectively. The interaction be­tween rootstock/scion indicated the highest BT in R3Si and R2S2.
Reliable and reproducible protocols to get healthy and well formed plants from juvenile explants of the pomegranate (Punica granatum L.) cv. 'Kandhari Kabuli' have been developed. Calli were initiated from cotyledon, hypocotyl, leaf and internode sections excised from 30 days old in vitro germinated seedlings. The best media for callus induction from cotyledon, hypocotyl, internode and leaf explants were MS medium supplemented with 13.0 ^M NAA and 13.5 ^M BA, 13.0 ^M NAA and 18.0 ^M BA, 5.0 ^M IBA and 9.0 ^M BA, 8.0 ^M NAA and 9.0 ^M kinetin, respectively. The highest percentage of callus was obtained from cotyledon explants (85.50) followed by hypocotyl (79.67), internode (79.47) and leaf (75.48) explants. The calli thus obtained showed differentiation on MS medium supplemented with 9.0 ^M BA and 2.5 ^M NAA. Cotyledon derived callus showed the highest regeneration rate (81.97%, with mean number of 16.47 shoots per explant) followed by hypocotyl, internode and leaf derived calli. In vitro rooting was best on half strength MS medium containing 500 mg l-1 of activated charcoal. The plantlets with well formed root systems were transferred to plastic cups containing cocopeat followed by transfer to earthen pots containing soil and sand (1:1).
There is inadequate information on the application of rootstocks in the propaga­tion of pomegranate. The aim of this research was to study propagation of pomegran­ate using the stenting method. The experiment was conducted on the basis of a com­pletely randomised design (CRD) with two factors: rootstock (Rj, R2 and R3) and the concentration of indole-3-butyric acid (IBA) (0 and 500 mg/l), in three replications. The rootstocks were 'Gorj-e-Dadashi' (R1), 'Gorj-e-Shahvar' (R2) and 'Gool Safid-e- Ashk-e-Zar' (R3), and the scions were of the cultivarMalas-e-Yazdi. The results indi­cated that rootstock type and IBA treatment influenced bud-take and root formation. The highest bud-take percentage was obtained with R1 in combination with 500 mg/l IBA.
In recent times, pomegranate has been one of Turkey’s most important commercial fruit crops for consumption and export. In this study, the chemical composition of pomegranate (Punica granatum L.) fruits grown in the central area of Bitlis province (Eastern Turkey) was investigated. For this purpose, total phenolic content, ascorbic acid content, total anthocyanin and antioxidant activity and minerals content were evaluated. The highest total phenolic contents were determined in 13BIT1 (6477.78 mg gallic acid equivalents 100 g–1 fresh matter). The highest ascorbic acid was determined in 13BIT2 of pomegranate genotype (60.78 mg 100 g–1). Radical scavenging activity (DPPH) were determined between 13BIT18 (78.15) to 13BIT1 (31.49). Total anthocyanin of genotypes was measured between 13BIT19 (156.03) to 13BIT17 (55.37), respectively. The highest mineral compositions of the pomegranate genotypes were 998.00% N, 301.00 mg 100 g–1 P, 1708.61 mg 100 g–1 K, 55.21 mg 100 g–1 Ca, 116.79 mg 100 g–1 Mg, 5.1 mg 100 g–1 Fe, 1.91 mg 100 g–1 Cu, 0.41 mg 100 g–1 Mn and 1.20 mg 100 g–1 Zn, respectively. The results indicate that pomegranate genotypes have an important value of health and nutrition for the human.
The antifungal activities of ethanolic extracts of three Saudi plants; camel thorn (Alhagi maurorum Medic.), caper (Capparisspinosa L.), and pomegranate (Punica granatum L.) were investigated in vitro against Alternaria alternata, Fusarium oxysporum, Phomadestructiva, Rhizoctonia solani, and Sclerotium rolfsii at concentrations of 0, 3, 6, and 9% (v/v). All tested plant extracts; seeds, roots, and rinds had different degrees of antifungal activity against the tested fungi. When compared with the control, the highest antifungal activity was recorded for camel thorn seeds extract at a concentration of 9%, while, pomegranate rinds extract at 9% came in second. Camel thorn rinds extract came in last even when used at a high concentration. The ethanolic extract of camel thorn seeds may be recommended as a potent bio-fungicide. Extensive studies should be undertaken for the ethanolic extract of camel thorn seeds as a strong antifungal agent against fungal plant diseases.
