Cymbidium erythrostylum Rolfe is one of the most beautiful species genus cymbidium which used as a cut flower or indoor plant. However, it was registered rare even in its original habitat. This study carried out to develop protocol for vitro propagation C. erythrostilum. We protosomes obtained by asymbiotic germination seed on 1/2 Murashige and Skoog nutrient medium (MS) supplemented with 1 mg/...

For problems SAT and MAX SAT, local search algorithms are widely acknowledged as one of the most e ective approaches. Most of the local search algorithms are based on the 1ip neighborhood, which is the set of solutions obtainable by ipping the truth assignment of one variable. In this paper, we consider rip neighborhoods for r 2, and propose, for r = 2; 3, new implementations that reduce the nu...

An efficient regeneration system through somatic embryogenesis was developed for date palm cv. Najda. Adventitious bud and proximal leaf segments cultured on Murashige and Skoog (MS) medium supplemented with various combinations of auxins and cytokinins induced embryogenesis after at least 6 months of culture. Somatic embryogenesis induction seemed correlated with the type of the explant, the i...

Callus growth and plant regeneration from long-term callus cultures were studied in two elite clones of Asparagus officinalis cv. Argenteuil, to establish a suitable protocol for a prospective in vitro selection program. Callus initiation and growth was evaluated on MS medium with 3% sucrose, 0.9% agar, 1 mg x l(-1) kinetin, and three levels of 2,4-D. The highest callus relative growth was obta...

Abstract Pulsatilla turczaninovii is an important medicinal plant, valued for high ornamental value of melliferous flowers. We assessed the efficiency reproduction under in vitro conditions and ex situ growth capacity this representative world flora. The seed germination percentage was assessed, followed by determination micropropagation rate rooting efficiency. Then, possibility plant developm...

Pelargonium quercetorum Agnew grows naturally in the Hakkari province of Türkiye. Although P. has potential use as a medicine and ornamental plant, it is especially used medicinal plant for cure various diseases by local people. In vitro tissue culture methods are favorable propagation, conservation, breeding plants. We aimed this study to achieve regeneration from different explant types. Seed...

A liquid overlay culture system in micropropagation improved shoot proliferation many species. In the present investigation, we have developed an enhanced protocol using double phase (DPS) for Vanilla andamanica, endemic species of Andaman and Nicobar Islands recognized under vulnerable category by IUCN. vitro generated nodal explants were used experiments tested Murashige Skoog medium augmente...

The Andean mortiño (Vaccinium floribundum Kunth) grows wild in the northern paramos of South América. berries present potential opportunities for agribusiness, but an efficient technology production plants and is required. On other hand, development plant methods from seeds will allow plants’ accessibility its use breeding programs. objective this study was to develop vitro protocol accelerated...

Geometric and position isomers of zeatin and of ribosylzeatin and other compounds closely related to zeatin have been tested in the tobacco (Nicotiana tabacum var. Wisconsin No. 38) bioassay. None was more active than zeatin itself. There was a much greater difference in activity (> 50-fold) between transand cis-zeatin than between trans-isozeatin [6(4-hydroxy-2-methyl-trans-2-butenylamino)puri...
