Pure cultures of a gram-negative, rod-shaped bacterium, which produced endospores after 3 to 5 days on solid medium, were isolated exclusively from tissue cultures of the date palm Phoenix dactylifera L. Electron microscopic examination of thin sections of the bacteria revealed the bilayer membrane typical of gramnegative bacteria and confirmed the nature of the spores as true endospores. Bioch...

The anticonvulsant effects of 3,4-Dimethoxy toluene (DMT), the major constituent of the date palm (Phoenix dactylifera L.) spathe, were investigated using pentylenetetrazole (PTZ), picrotoxin (Pic), nicotine (Nic) and maximal electroshock (MES)-induced seizure models. In PTZ (85 mg/kg)-induced seizures, the intraperitoneally injection of DMT at a dose of 100 mg/kg significantly delayed the onse...

BACKGROUND To study the effects of an aqueous extract of date fruit (Phoenix dactylifera L. Arecaceae) diet on diabetic polyneuropathy (DPN) in streptozotocin- (STZ-) induced diabetic rats. METHODS The effects of a date fruit extract (DFE) diet on diabetic neuropathy in STZ-induced diabetic rats were evaluated and compared with a nondiabetic control group, diabetic control group (sham), and v...

The cadmium (Cd), a heavy metal, causes toxicity, which leads to hampering the growth and development of the plant. The molecular and biochemical approaches were used for the investigation of antioxidant system response and genotoxicity in date palm (Phoenix dactylifera L.) cv. Sagai in pot experiment having Cd. The root length was more affected than the shoot length as more accumulation of Cd ...

This study aimed to investigate the effects of date (Phoenix dactylifera L.) kernel essential oil on growth and development performance parameters as well phagocytic activity, respiratory burst superoxide dismutase, lysozyme myeloperoxidase activity from immune rainbow trout (Oncorhynchus mykiss). The nutritional was performed for 45 days assess effect three concentrations (0.5, 1, 2 mL kg-1) i...

Iran is one of the main date (Phoenix dactylifera) producing countries in the world. however, little information is available on the pollen viability and favorable storage conditions of Iranian male date cultivars. This study was conducted to estimate the best in vitro pollen germination of three male date palm cultivars, `Ghanami’, `Samsmavi’ and `Gheibani’ using various doses of boric acid (0...

The present research was accomplished on Phoenix dactylifera L. cv. Shahany to investigate the effect of macro and micronutrients on fruit quality and quantity. Treatments were urea (0.5, 1%), boric acid (1500, 2500 ppm), potassium sulfate (1, 2%) and zinc sulfate (300, 600 ppm). Higher and lower yield were obtained from H BO (1500 ppm) and control, respectively. The greater part of pulp weight...

Exogenous indole butyric acid had a significant positive effect on the rooting response of date Palm (Phoenix dactylifera L.) offshoots. IBA-treated offshoots rooted earlier and with a much higher frequency while untreated offshoots rooted poorly, later, and tended to produce fewer roots. The effect of exogenous application of auxin was also reflected in the metabolic changes in offshoots durin...

Now a day’s many herbs and plants their species consumed as food in our daily life because of its effectiveness preventive nature towards health. The Phoenix dactylifera Linn. is most common plant usually known date palm, belonging to the family Arecaceae. It native North Africa, South- West Asia considered an oldest plant. palm well for traditional medicinal value. active phytoconstituents rep...
