The use of nanoparticles in sensing is attracting the interest of many researchers. The aim of this work was to fabricate Acacia gum-stabilised silver nanoparticles (SNPs) using green chemistry to use them as a highly sensitive and cost-effective localised surface plasmon resonance (LSPR) colorimeter sensor for the determination of reactive oxygen species, such as hydrogen peroxide (H2O2). Silv...
This study was directed at the understanding of the function of CCoAOMT isolated from Acacia auriculiformis x Acacia mangium. Full length cDNA of the Acacia hybrid CCoAOMT (AhCCoAOMT) was 1024-bp long, containing 750-bp coding regions, with one major open reading frame of 249 amino acids. On the other hand, full length genomic sequence of the CCoAOMT (AhgflCCoAOMT) was 2548 bp long, containing ...
Constant reduction of stratospheric ozone layer and the increase of ultraviolet radiation intensity were observed in last twenty years of the 20th century. Four tree species; Acacia amplicepsis, Acacia gerradii, Casuarina glauca and Eucalyptus intertexta grown in Experimental station of Food and Agriculture Sciences Collage, King Saud University were used to study the impact of UV-C on potentia...
تنش شوری یکی از تنش های غیر زنده محسوب می شود که با توجه به تأثیرات منفی بر روی رشد گیاهان، پتانسیل تولید اراضی زراعی را کاهش می دهد. از آنجا که جوانه زنی گیاه، اولین مرحله ای است که با شوری خاک مواجه می شود، لذا شناسائی مقاومت گیاه در این مرحله و نیز مراحل اولیه رویشی می تواند کمک زیادی در شناسائی گونه های مقاوم به شوری با صرف زمان کوتاهی نماید. که این کار در سال های اخیر مورد توجه قرار گرفته ...
Seeds of many arid habitat plants have a water-impermeable coat and can germinate only after being scarified. Bruchine seed beetles are important parasites of legume seeds in these environments, but their effect on germination can be unpredictable. Beetles deplete seed resources and can kill the embryo but also scarify seeds. We investigated the effects of a generalist parasite, Stator limbatus...
Aim of the study: To determine the pharmacological activity relevant to ulcer healing of Acacia farnesiana (aroma) leaf, a folk medicine used in the treatment of Ulcer. Materials and Methods: MEAF extract was done by using soxhelet apparatus and was further subjected to screening of the qualitative analysis of phyto chemicals. Consequently the Methanolic extract of leaf was tested against ulcer...
We report the chemopreventive activity of Acacia nilotica (Linn.) gum, flower and leaf aqueous extracts, on 7,12-dimethylbenz(a)anthracene (DMBA) induced skin papillomagenesis in male Swiss albino mice. Animals were divided into following groups: Group I (Controls) given DMBA and croton oil, with no extract ; Group II (treatment) animals treated with Acacia nilotica gum (Group II-a) (800 mg/kg ...
to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...
گونه acacia seyal var. seyal از گیاهان چند منظوره در آفریقا و آسیا است. دراین مطالعه ریختار گیاه مورد بررسی قرار گرفته است. این گونه بر اساس رنگ پوست در مراحل بلوغ و نونهال به 3 گروه قابل تفکیک است. نتایج حاصل از اندازه گیری های کمی مورد تجزیه و تحلیل آماری قرار گرفت و در بین گروه های مختلف اختلاف معنی دار وجود دارد. در نتیجه 3 شکل بر اساس رنگ پوست پیشنهاد می گردد.
