periwinkle (vinca minor l.) is an evergreen perennial herbaceous plant that belongs to the family apocynaceae. the aerial part of this plant contains certain alkaloids such as vincamine, isovincamine and vincine. the most important of these is vincamine that re-duces blood pressure and promotes memory and the ability for mental concentration. mi-cropropagation could be a good alternative for th...

for half a century, the limitations of obtaining cross-combinations in lilies because of the incompatibility and incongruity between different varieties have been known. somatic hybridization is one of the most powerful tools for achieving distant interspecific hybrids. for this purpose, protoplast preparation is a first and important step in efficient system for the regeneration of plants from...

two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...

background & aim: considering that antioxidants are known as effective free radicals scavenger, it may be able to improve the in vitro oocyte maturation and the fetal quality. this study was designed to determine the effect of gundelia tournefortii leaves (gte) hydro-alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: germinal vasicle (gv) were recovere...

background & aim: oocytes in vitro maturation is an enormously promising technology for the treatment of infertility, yet its clinical application remains limited owing to poor success rates. therefore this study was designed to determine the effect of gundelia tournefortii root hydro alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: in this study, th...

interactive effect of plant growth regulators6-benzylaminopurine (bap) (0, 2, 4 and 8 µm) and1-naphtalene acetic acid (naa) (0, 0.05, 0.25 and 0.5µm) in van der salm (vs) medium was used to optimize in vitro propagation of rosa hybrida cv. iceberg.shoot proliferation and number of new leaves weremeasured as growth indicators. as the concentrationof bap was raised, growth rate increased with all...
