RAPD analysis This study aimed to develop an efficient method for micrpropagation of true-to-type date palm plants through direct organogenesis. Nodular cultures were obtained from shoot tips on MS medium plus 2 mg/l 2ip and 1 mg/l NAA. Among combinations of 2ip and 2,4-D added to culture medium for direct shoot buds proliferation, 5 mg/l 2ip alone gave the highest organogenesis frequency. For ...

Lemongrass (Cymbopogon citratus) essential oil (EO) is a major source of bioactive compounds (BC) with anticancer activity such as ?-citral, limonene, geraniol, geranyl acetate, and ?-caryophyllene. Comparative studies about cytokinin effects on BC profiles in lemongrass are missing. Here, we evaluated four cytokinins (2iP, tZ, BAP, KIN) two different osmotic media, MS-N (3% sucrose, 3 g L?1 Ge...

The growth rates of tobacco callus tissues on media containing 10(-6) to 10 mum 6-(gamma,gamma-dimethylallylamino)purine (2iP) were measured. At concentrations of 10(-4) mum and above growth rates were exponential and dependent on cytokinin concentration. At 2iP concentrations of 10(-4) to 0.33 mum, the exponential rate was maintained for 4 to 5 doublings of fresh and dry weight. After this per...

This paper studies the tilings with colored-edges triangles constructed on a triangulation of a simply connected orientable surface such that the degree of each interior vertex is even (such as, for (fundamental) example, a part of the triangular lattice of the plane). The constraints are that we only use three colors, all the colors appear in each tile and two tile can share an edge only if th...

Multiple shoot clumps or microclones were collected from two onion (Allium cepa L.) varieties for bulblet formation. MS medium supplemented with various concentrations of BAP, Kn, 2ip and NAA used. The height responded was observed 90% 80% in Taherpuri Indian variety, respectively on 2.0 mg l-1 BAP+0.5 NAA. best formation obtained containing 1.0 2ip. Finally, the rooted bulblets hardened establ...

In the present investigation, the influence of different forms of cytokinins, auxins and polyamines were tested for mass multiplication and regeneration of cotton. Initially, for the identification of effective concentration for multiple shoot induction, various concentrations of BAP, Kin and 2iP along with IAA and NAA were tested. Among tested concentrations, media fortified with MS salts; B5 ...

The purpose of the PRACE RI is to provide a sustainable high-quality infrastructure for Europe that can meet the most demanding needs of European HPC user communities through the provision of user access to the most powerful HPC systems available worldwide at any given time. In tandem with access to Tier-0 systems, the PRACE-2IP project will foster the coordination between national HPC resource...

Abstract Shoot proliferation is a very important micropropagation phase, decisive for economic efficiency of this method given taxon. To obtain high multiplication ratio and good quality microshoots detailed propagation protocol must be developed particular species or even cultivars. Rhododendron ‘Kazimierz Odnowiciel’ relatively new cultivar distinguished by large, beautiful flowers frost resi...

We construct a computable sequence of computable reals 〈Xi〉 such that any real that can compute a subsequence that is maximal with respect to the finite intersection property can also compute a Cohen 1-generic. This is extended to establish the same result with 2IP in place of FIP.
