روش درون شیشه ای کشت تخمدان به منظور تولید گیاه Argania spinosa L. sKeels و افزایش درصد جوانه زنی بذور آن به کار گرفته شد. ضدعفونی سطحی بذور با اتانول 70% شستشو با آب مقطر استریل انجام شد. تخمدانها پس از حذف درون بر (اندوکارپ) سخت میوه ایزوله شده است. تخمدانها پس از ضدعفونی سطحی در قالب دو تیمار، کامل و برش دارشده در محیطهای کشت جامد wpm،ws وHalf-mکشت شدند. بیشترین درصد جوانه زنی جنین در ق...
A new phenolic-type compound containing a nitrogenous, heterocyclic-fused ring from the fruit of the argan tree, Argania spinosa (Skeels L.), is described. This and another already known compound also isolated in the course of the work belong to an obscure and rare class of natural products, the amino phenolics.
Xylan-type polysaccharides were isolated from the leaves of Argania spinosa (L.) Skeels collected in the Tindouf area (southwestern Algeria). Xylan fractions were obtained by sequential alkaline extractions and purified on Sepharose CL-4B. The xylan structure was investigated by enzymatic hydrolysis with an endo-β(1→4)-xylanase followed by chromatography of the resulting fragments on Biogel P2,...
Populations of the South-western part of Morocco traditionally use the fruits of Argania spinosa (L.) Skeels to prepare an edible oil whose obtainment furnishes, as side product, a cake used to feed the cattle and complemented the forage furnished by the leaves and fruits of this same plant. However, the wood of A. spinosa is also used for fuel and the subsequent induced deforestation is nowada...
The pectin polysaccharides from leaves of Argania spinosa (L.) Skeels, collected from Stidia area in the west coast of northern Algeria, were investigated by using sequential extractions and the resulting fractions were analysed for monosaccharide composition and chemical structure. Water-soluble pectic (ALS-WSP) and chelating-soluble pectic (ALS-CSP) fractions were obtained, de-esterified and ...
The argan tree, an endemic species in Morocco, has been exhaustively studied its southwestern range but neglected northeastern territory. Thus, the present study sets as objectives identification of arbuscular mycorrhizal fungi and evaluation tree’s roots’ mycorrhization level two stations: one region Béni Snassène (Berkane): Jebel Takermine with 7 prospected sites other at Aklim Alkabir 2 site...
