Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Our objective was to identify microsatellite markers that could be used to differentiate between male and female date palm (Phoenix dactylifera). The date palm is a dioecious plant whose sex cannot be determined until it reaches a reproductive age between 5 and 10 years. An early selection...

Palm sap tapped from three varieties of date palm Phoenix dactylifera was analyzed during two tapping periods: winter and springtime. These samples were collected once-a-week during 14 weeks for each tapping period. Total soluble solids decreased during tapping period; however no significant variation was noted for pH and titrable acidity. The microbial count indicated that after an initial hig...

background: in algeria, date palm is currently confronted to the bayoud disease. biotechnological tools such as protoplasts fusion can appear as an alternative to ensure rapid multiplication and improvement of this species.objectives: callogenesis induction in protoplasts isolated from embryogenic callus of three date palm cultivars.materials and methods: some factors influencing the isolation ...

to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...
