Acacia species are quite difficult to differentiate using morphological characters. Routine identification of Acacia samples is important in order to distinguish invasive species from rare species or those of economic importance, particularly in the forest industry. The genus Acacia is quite abundant and diverse comprising approximately 1355 species, which is currently divided into three subgen...

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...
Raru is a lesser-known plant species originating from North Sumatra, Indonesia. Information on the characteristics still limited, especially its chemical component. Therefore, this study aims to examine composition information of Cotylelobium lanceolatum, melanoxylon, and Vatica pauciflora woods based their axial log positions (bottom, middle, top). The wood analysis was performed in terms Indo...
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.

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...
The study was carried out on the availability and utilization pattern of various wild plant species by migratory elephants in relation to their nutritive values. It wasobserved that migratory elephants were selective for food plants in the wilderness. Out of 52 recorded plant species, only 22 plant species were found to be utilized either fully or partially as evidenced by branch breaking, deba...
