background: the complex process of spermatogenesis is regulated by various factors. studies on spermatogonial stem cells have provided a very important tool to improve herd genetic and different field. 0.2 to 0.3 percent of total cells of seminiferous tubules consist of spermatogonial stem cells. to investigate and biomanipulate these cells, first the proliferation and viability rate of cells s...

Aloe vera is an important medicinal perennial herb belonging to the family liliaceae. A method for mass propagation of Aloe vera by using different explants and different media with different PGR contain has been developed. Two type of explants (with and without sheath Type A and B respectively) were cultured on MS, B5 and SH media supplemented with different combination of different NAA with B...

This study describes the in vitro propagation and ex acclimatization of Philodendron erubescens pink princess, one most popular ornamental variegated foliage plants. For shoot proliferation, protocorm-like bodies princess were cultured on solid Murashige Skoog (MS) media supplemented with 6-benzylaminopurine (BAP) 1-naphthaleneacetic acid (NAA) at different concentrations. The results revealed ...

Abstract Plant cells cultivated in vitro are a convenient model for studying the genetic and physiological mechanisms necessary to acquire state of pluripotency. Earlier studies on plant Arabidopsis thaliana (L.) Heynh. have identified key role genes that determine pluripotency shoot apical meristem de novo regeneration tissue culture. In accordance with this, mutant plants higher level express...

Cinchona officinalis is an important species from the Andean cloud forest that has a low regeneration rate in natural populations. In vitro of C. been successfully established but somaclonal variation was not evaluated. The pathway and number subcultures on were evaluated using six ISSR primers amplified 58 loci Inter Simple Sequence Repeats (ISSR). A dendrogram based Jaccard´s genetic distance...

Orange is one of the most horticulturally important and widely cultivated Citrus species. cultivar improvement via conventional breeding strategies normally impeded by factors related to its reproductive biology. The present study was undertaken investigate optimization growth regulators’ composition media in vitro propagation orange from nodal segment explants. explants were collected sweet cu...
