  Introduction: Raspberry has been considered a good source of some micro and macro nutrients namly (anthocyanins, polyphenol, ascorbic acid, fiber, proteins and minerals). Due to high metabolic activity and susceptibility to fungal decay and especially gray mold, it is one of the most perishable fruits and has a short shelf life. The use of modified atmospheric packaging increases the shelf life of the fruits like raspberries and therefore the commercial value of the fruit is increased. Materials and Methods: In this study the RSM design is used to assess the effects of three variables; CO2/O2 (three levels; zero, one and two v/v), time (0, 5 and 10 days) and perchlorine concentration (0, 250, 500ppm) on raspberry weight loss, acidity, texture and microbial load. Rasberry fruits were packed in the two layer plastic packaging made of polyamide with thickness of 50 microns and stored at 4˚C Results: The results showed that the time, perchlorine concentration and CO2/O2 ratio had significant effects on the qualitative properties of raspberry fruit and its shelf life. Increases in perchlorine concentration and CO2/O2 ratio had positive effects on keeping quality of the fruit. Conclusion: The application of modified atmospheric packaging can improve the qualitative characteristic of raspberry fruit. Manuscript profile

  Blackberries produce several types of phytochemicals beneficial to human health and wild blackberries are richer than cultivated ones. Climatic conditions have a great impact on plants in various ways. In this experiment, wild blackberries from two regions in the west and east of Golestan province (Bandar-e-Gaz and Minoodasht regions), in each region from two places (plain and foothills) and two different seasons of fruit ripening (late spring and late summer) were sampled and studied for morphological and phytochemical traits. The results showed that the region and place of growth and harvest season had a great impact on the morphological and phytochemical traits of wild blackberry fruit. Blackberries harvested from Bandar-e-Gaz had higher inflorescence length and width than blackberries of Minoodasht. There was a significant difference between spring and summer blackberries respecting the number of fruits per inflorescence and the number of drupelets per fruit. There was also a significant difference between spring and summer blackberries in all fruit traits, including fruit length, diameter, and weight. The fruits of Bandar-e-Gaz blackberries were more spherical (L/D 0.97) and had a higher fresh weight (1.23 g). The results also showed a significant difference between the blackberries of the two regions and between the two harvest seasons in total acidity, ascorbic acid, and pH. Spring fruits harvested in Minoodasht showed the highest amounts of acidity (5.52 mg/100mg) and total soluble solids (°Brix) and the lowest amount of pH (2.28). Blackberries harvested in Minoodasht region had more total anthocyanin (1.245 mg/100ml) but less total flavonoids (0.471 mg/100ml) and total phenols (0.36 mg/100ml) than blackberries harvested in Bandar-e-Gaz region. There was a significant difference between spring and summer fruits of both regions respecting the above-mentioned traits as well as antioxidant activity; spring fruits showed higher values ​​in most of them. It seems that the climatic conditions of the region are more suitable for the cultivation of spring blackberry cultivars and the fruits obtained from these cultivars and genotypes have higher nutritional and medicinal properties.

  The raspberry (Rubus ulmifolius subsp. Sanctus) is the perennial shrub in the genus Rubus of the Rosacea family. It is a medicinal and edible fruit throughout much of Khandaracy region of Urmia. Raspberry fruits are most important in food and medicinal sciences due to their excellent antioxidant activity and various flavonoids and proanthocyanin content. In this research, after harvesting fruits from the Khandaracy region of Urmia in the late summer, pH level by pH meter, organic acids by titration with 0.1 molar NaOH, Soluble solids using a refractometer, total phenolic content (by using Folin–Ciocalteu assays), total flavonoid content (aluminum chloride method), antioxidant capacity by two methods (DPPH and FRAP), total anthociyanin content (pH differential method), L-phenylalanine ammonia-lyase (PAL) and (guaiacol peroxidase) G-POD enzymes were determined. The results showed that level pH, organic acids and soluble solids were respectively 3.13, 1.14, 12.6, also values of total phenol content, total flavonoid, antioxidant activity and total anthocyanin content were 26.44 mg GAE.ml-1 Extract, 1.99 mg Qu. ml-1 extract, 55.29 % and 63.78 cyanidin-3-glucoside ml-1 Extract respectively. The results of this study showed that raspberry fruit has high content of polyphenol compounds and has significant antioxidant activity, so it can be used in food and pharmaceutical industries.

  The objective of this work was to evaluate the effect plant growth regulator, silicic acid, sucrose and activated charcoal used in micro propagation of thornless Blackberry cv. Merton explants. Propagules of cv. Merton were cultivated on a 1/2 Murashige and Skoog (MS) medium. The single buds were cultured in 1/2 MS containing 0.1% activated charcoal and new shoot containing buds were formed 3 weeks after culture. New buds were cultured in MS containing BA, Kin and IBA at concentrations of 0.2, 0.5, 1, 1.5 and 2 mgL-1 for shoot regeneration. New shoot after 6 weeks regenerated and the best medium for shoot regeneration was MS medium contains 1.5 mg/l BA and 0.1 mg/l IBA. Shoots were cultured in 1/2 MS containing 0.2, 0.5, 1, 2 mgL-1 NAA and IBA for root formation. After determining the optimal concentrations of IBA and NAA, activated charcoal in concentrations of 0.01, 0.02, 0.05, 0.1, 0.2%, silicic acid in concentrations of 0, 1, 5, 10, 20 mgL-1, sucrose in concentrations of 1, 2, 3, 4, 5% were added to the culture medium to improve rooting. Sucrose in 4% increased the root length, root weight and chlorophyll content. The addition of activated charcoal in the MS medium resulted in increased shoot and root length. In thornless blackberry cultures, Silicic acid decreased the shoot number but until 5 mg/l increased the shoot length. Silicic acid increased the root length in 1 mg/l and increased the root weight in 5 mg/l rather than control respectively. Manuscript profile

  The genus Rubus L. belongs to the genus Rosaceae. This genus includes more than 750 species in the world. Among some species of this genus such as R. dolichocarpus Juz. And R. ochthodes Juz. Morphological similarity is observed in traits such as the number of leaflets, the shape of the earrings and the color and shape of the petals, which makes it difficult to identify these two closely related species. The species R. dolichocarpus in the flora of Iran is declared synonymous with the species R. ochthodes, while these two species in the flora of Iranica, the flora of Russia and the flora of Iran are two separate species in one subgenus and two different segments. For this purpose, in this study, the taxonomic relationships of these two species based on morphological characteristics were investigated. The results indicate differences in morphological traits such as the shape and condition of the annual stem, the shape of lateral leaflets in the flowering stem, the shape of the leaflets. And the density of flowers in the inflorescence. Also, according to molecular data using the ITS nuclear marker, these two species have 36 different nucleotides, which confirms the separation of the two species. Therefore, according to the results obtained in this study and comparison with previous studies, it is suggested that two species of R. dolichocarpus and R. ochthodes. According to the flora of Iranica, the flora of Russia and the flora of Iran should be defined as two separate species. Manuscript profile
