Scented rose species are very important in the genus Rosa due to their use in highly-prized essential oil production and as garden roses. The fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. A comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly Damask ...

An increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(Prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. Information on this subject is limited at the present time. In search of superior nectarines, a trial was conducted to study growing degree days (GDD), fu ...

In this study, an efficient Agrobacterium-mediated transformation method was developed forpomegranate (Punica granatum L.), a difficult-to-transform plant. In vitro shoot segments wereinoculated with Agrobacterium tumefaciens strain LBA4404 harboring the binary vectorpBI121 carrying the neomycin phosphotransferase (nptII) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter ...

We examined the effectiveness of intermittent warming (IW), hot water (HW), salicylic acid (SA), and calcium chloride (CaCl2) on the postharvest life of pomegranate fruit cv. ‘Shishe-Kab’ and extending fruit shelf life during cold storage (3°C). Fruit were subjected to cycles of 1 d at 17 ± 1°C every 6 d of storage at 3°C under IW conditions. Pre-storage treatments were HW (50°C) for 3 min, SA ...

Aril browning threatens production, consumption, and exports of pomegranates, because affected fruit cannot be externally distinguished from healthy fruit. This study compared the mineral, biochemical composition, and related enzyme activities in affected brown arils with healthy ones in ‘Malase Saveh’ pomegranates. The results indicated that concentrations of Cu in the aril and K, Mg, and Mn ...

Tuberose (Polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. Thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. Tests were done to examine the effects on of nano-silver (NS) (0, 15, 30 and 45 mg L-1) and sucrose (0, 4 an ...

This study was undertaken to identify morphological changes in young seedlings of 5 Iranian almond species (Prunus dulcis, P. eburnea, P. eleagnifolia, P. haussknechti, and P. scoparia) under polyethylene glycol-induced drought stress. Drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf r ...

The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rate ...

One of the most effective ways to propagate Lilium is by using tissue culture techniques, preferably through bulblet production. In addition to the surviving percentage of Lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing Lilium micropropagation. Different concentrati ...

Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyl ...
