Anthropogenic habitat modification often has a profound negative impact on the flora and fauna of an ecosystem. In parts of the Middle East, ephemeral rivers (wadis) are characterised by stands of acacia trees. Green, flourishing assemblages of these trees are in decline in several countries, most likely due to human-induced water stress and habitat changes. We examined the importance of health...
The tribe Acacieae (Fabaceae: Mimosoideae) contains two genera, the monotypic African Faidherbia and the pantropical Acacia, which comprise about 1200 species with over 950 confined to Australia. As currently recognized, the genus Acacia is subdivided into three subgenera: subg. Acacia, subg. Aculeiferum, and the predominantly Australian subg. Phyllodineae. Morphological studies have suggested ...
Gum Arabic (GA) or Acacia gum is an edible biopolymer obtained as exudates of mature trees of Acacia senegal and Acacia seyal which grow principally in the African region of Sahe in Sudan. The exudate is a non-viscous liquid, rich in soluble fibers, and its emanation from the stems and branches usually occurs under stress conditions such as drought, poor soil fertility, and injury (Williams & P...
Prspopis Juliflora and acacia Acacia victoriae species of precious and semi-arid and arid regions that are compatible with wood and charcoal production, soil conservation, forage production and medicinal value are very important and acacia, and stimulated their germination has been studied. Treatments used to overcome seed dormancy were treated with concentrated sulfuric acid 98% (H2so4), 15 mi...
ذخیرهسازی در فراسرد یا C°196- روشی جدید و بسیار کارآمد در نگهداری بلندمدت ژرمپلاسم گونههای گیاهیست. با استفاده از روش فراسرد میتوان بذر، اندام رویشی، سلول و دانه گرده گیاهان را برای بلندمدت نگهداری و در صورت بروز هر گونه تهدید یا خطر انقراض نسبت به بازگشت و احیاء گونه اقدام کرد. در شرایط فراسرد، اغلب فعالیتهای متابولیکی سلول تقریباً متوقف و طول مدت نگهداری بطور چشمگیری افزایش مییابد. ب...
Pollen from the Acacia has been reported as an important source of pollinosis in tropical and subtropical regions of the world. The aim of this study was to characterize the IgE binding protein of Acacia farnesiana pollen extract and evaluate cross-reactivity with the most allergenic pollens. In this study, pollen extract was fractionated by SDS-PAGE and the allergenic profile was determined by...
Exploiters of protection mutualisms are assumed to represent an important threat for the stability of those mutualisms, but empirical evidence for the commonness or relevance of exploiters is limited. Here, I describe results from a manipulative study showing that an orb-weaver spider, Eustala oblonga, inhabits an ant-acacia for protection from predators. This spider is unique in the orb-weaver...
The aim of this study is to determine the effect of methanol crude leaves extract and aqueous fraction of Acacia nilotica on liver enzymes and lipid profiles of alloxan induced diabetic Wistar rats. Diabetes was induced by a single intraperitoneal injection of alloxan dissolved in 0.9%v/v cold normal saline solution at a dose of 150 mg/kg body weight, after which the rats were randomly divided ...
Xanthomonas axonopodis punicae is the causative agent of Bacterial blight of Pomegranate that is known to cause yield loss up to 70-90%. The primary disease management method involves mainly use of chemical pesticides. In present investigation the antibacterial activity of extracts of Acacia nilotica, Datura metel, cow urine and butter milk against Xanthomonas axonopodis punicae was studied by ...
Study was aimed to evaluate the possible antisecretory and antiulcer activity of crude bark extract of Acacia catechu and its action against indomethacin an non steroidal anti inflammatory drug (NSAID) plus pyloric ligation induced gastric ulcers in rats. Administration of crude extract of Acacia catechu (400mg/kg/day p.o.) significantly reduced ulcer index when compared with indomethacin induc...
