Elaeagnus umbellata is a deciduous shrub widely distributed in the Himalayan regions of Pakistan. The reddish berries of the plant are edible and very delicious. In the present study, the berries of the plant were investigated for proximate composition, mineral content, physicochemical characteristics, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and selected phytochemicals. The results showed that the fruit of E. umbellata contained 71.4% moisture, 2.9% ash, 4.0% protein, 2.3% crude fat, 5.9% fiber and 13.6% nitrogen free extract. The nutritive value of the fresh berry was 90.8 kcal/100 g. The berry contained 27.8 mg/100 g of vitamin C. The plant showed striking DPPH scavenging activity and the phytochemical analysis revealed that it contained 23.3, 3.6, 19.9, 126.5, 12.6 and 21.2 mg/g of phenolic, flavonoid, carotenoid, tannin, alkaloid and saponin contents, respectively. In short, this study showed that E. umbellata is a good source of various nutrients and antioxidant compounds, and it can be beneficial to consumer's health.

“…Leaves are elliptic with entire margins, having sparse stellate trichomes on adaxial surfaces, and a dense covering of peltate trichomes on abaxial surfaces. Elaeagnus umbellata is native to coarse-textured, moderately or well-drained soils of Asia (Ahmad et al 2006), but was introduced to North America as an ornamental shrub and has spread from cultivation in the mid-and eastern United States (Ebinger and Lehnen 1981). While many introduced species tend to establish and thrive in edge areas and fragmented forests (Benítez-Malvido and Martínez-Ramos 2002), E. umbellata also succeeds in the understory of pre-existing forests (Yates et al 2004).…”

Photosynthesis, chlorophyll fluorescence, and hyperspectral reflectance were used to evaluate diurnal changes of Elaeagnus umbellata to quantify physiological responses of the invasive species during times of stress. Field measurements showed that E. umbellata is able to maintain higher levels of photosynthesis relative to nearby Quercus alba plants, with less water loss. Plants subjected to progressive drought were able to recover photosynthesis one day following re-watering. Laboratory and field measurements revealed decreasing DF/F 0 m values in response to drought stress, with little corresponding decrease in photochemical reflectance index values. This research supports the view that xanthophyll cycle dissipation is not the photoprotective mechanism at work for Elaeagnus species under water stress. Elaeagnus umbellata maintains photosynthetic carbon assimilation even under drought conditions, in part, due to chemical dissipation of excess light, and in part because of morphological features that limit excess radiation while maximizing photosynthetic carbon gain. These characteristics may contribute to the invasive success of E. umbellata.

Autumn olive (Elaeagnus umbellata Thunb.), belonging to Elaeagnaceae family, naturally spreads over Southern Europe and East Asia. It is a deciduous shrub or small tree growing up to 6 m in height and 9 m in width. Its form is rounded, with dense branches. The species can store the nitrogen in its roots. Thus, it has the ability to live even in the most inefficient soil. It is valued for its ability to prevent erosion and to attract wildlife and has been used in some agroforestry practices. When it is mature, the species has edible fruit with brilliant red or yellow pigmentation, and can be consumed especially as dried fruit. In addition, the greatest benefit of the fruit is the amount of lycopene it has. 100 grams of the fruit contains 7 to 17 times more lycopene than the same amount of tomatoes. Besides being extremely useful, antioxidant-containing fruits can be used in horticulture while leaves and flowers can be used in landscaping. Therefore, it is necessary to reproduce autumn olive for its uses in Turkey. Within the scope of this study, propagation of the species is carried out by hardwood cutting which is one of the vegetative propagation techniques. The objective of the present study is to investigate the effects of different auxins (IBA 1000 ppm, IBA 5000 ppm, NAA 1000 ppm and NAA 5000 ppm) on propagation of autumn olive by hardwood cutting in greenhouse condition with air temperature at 20±2°C, rooting table temperature at 25±2°C and perlite rooting media. The first root formation date, rooting percentage, root length and the number of roots were determined. The results showed that the highest rooting percentage occurred as 70% in NAA 5000 ppm and IBA 5000 ppm treatment. This study will provide a basis for further researches to be conducted using vegetative propagation methods.

Gü-ney Avrupa ve Doğu Asya'da doğal olarak yayılmaktadır. Kışın yaprağını döken, 6 m boya ve 9 m genişliğe kadar büyüyebilen çalı veya küçük ağaç formunda olan bir türdür. Yoğun dalları sayesinde yuvarlak forma sahiptir. Bitki köklerinde azotu depolayabilmektedir. Böylece, en verimsiz toprakta bile yaşama kabiliyetine sahiptir. Erozyonu önleme özelliği olan ve yaban hayvanlarının dikkatini çeken bir türdür. Ayrıca bazı tarımsal ormancılık uygulamalarında kullanılmaktadır. Parlak kırmızı veya sarı renk pigmentli meyveleri olgunlaşınca yenilebilir ve özellikle kurutulmuş meyve olarak tüketilebilir. Ayrıca, meyvenin en büyük faydası sahip olduğu likopen miktarıdır. 100 gram meyvede aynı miktardaki domatesten 7 ila 17 kat daha fazla likopen içerir. Son derece yararlı olmalarının yanı sıra antioksidan içeren meyveleri bahçecilikte, yaprakları ve çiçekleri ise peyzajda kullanılabilir. Bu nedenle, türün Türkiye'deki kullanımları için üretilmesi gerekm...
