Genetic Stability of Micropropagated Plantlets in Date Palm

Randomly amplified polymorphic DNA (RAPD) markers were used to analyze genetic stability of the somatic embryogenesis-derived regenerants (R1-6) and mother plant in Iranian date palm (Phoenix dactylifera L.) cultivar Khanizi. Total genomic DNA extracted from in vitro fresh leaves of regenerated plants and mother plant was amplified using 10-mer oligonucleotide Fermantas primers. Four primers of...

Date Palm Fruit Set and Quality as Influenced by Variations in Inflorescence Bagging Material following Pollination

Bagging of female inflorescence following pollination has recently received growers attention. Although this process occurs early in the season but affects fruit quality, yield, and marketability. Date palm growers have used to use grocery paper bags for this bagging process. Since inflorescence bagging causes what is called the greenhouse effect, it was very important to investigate the effect...

Effect of Nitrogen, Boron, Potassium and Zinc Sprays on Yield and Fruit Quality of Date Palm

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...

Al-Ayedh: Rearing the Red Date Palm Weevil 353 EVALUATION OF DATE PALM CULTIVARS FOR REARING THE RED DATE PALM WEEVIL, RHYNCHOPHORUS FERRUGINEUS (COLEOPTERA: CURCULIONIDAE)

Development of red date palm weevil Rhynchophorus ferrugineus (Olivier) was evaluated on 4 popular cultivars of date palm, viz., ‘Khalas’, ‘Sukkary’, ‘Khasab’, and ‘Sillaj’ for 2 consecutive generations. The weevils reared on ‘Sukkary’ showed significantly better growth expressed in most parameters such as length, width and weight at larval, pupal and adult stages. Significantly greater numbers...
