Higher plants are sessile therefore are continuously exposed to different environmental stress factors, such as drought, salinity, heavy metals, nutritional disorders, radiation without any protection. Most of these stresses produce certain common effects on plants, like induced oxidative stress by overproduction of reactive oxygen species (ROS), besides their own specific effects (Rao, 2006). ...

Tissue culture is an in-vitro technique for replicating a plant without introducing the degree of genetic variability inherent in sexual reproduction. Tissue culture has proven commercially important for the replication of ornamental varieties of house plants and is used extensively in research for applications in forestry. Activated carbon (AC) was initially added to tissue culture media in an...

Tissue culture is the in vitro aseptic culture of cells, tissues, organs or whole plant under controlled nutritional and environmental conditions [1] often to produce the clones of plants. The resultant clones are true-to type of the selected genotype. The controlled conditions provide the culture an environment conducive for their growth and multiplication. These conditions include proper supp...

Orchardgrass is a member of the Poaceae, a family characterized by monocotyledonous-type embryos. This species is unique in that somatic embryogenesis can be induced from the cultured leaves of potted plants, which can be maintained conveniently in the greenhouse. Both embryogenic callus and isolated somatic embryos develop directly from cultured leaf sections. Embryogenic callus can be maintai...

INTRODUCTION In 1902 Gottleib Haberlandt proposed the idea of growing individual plant cells on artificial medium. While Haberlandt never realized his idea, the 105 years since has seen the concept evolve into a powerful tool utilized throughout the plant sciences. Plant tissue culture broadly refers to growing plant cells, tissues, organs, seeds, or other plant parts in a sterile environment o...

plant tissue culture technique could provide sterile and controllable condition in order to assay direct effect of different compounds on plant growth accurately. in this study, the effects of aqueous extracts prepared from roots and shoots of goosefoot (chenopodium album l.), redroot pigweed (amaranthus retroflexus l.), fennel (foeniculum vulgare), and wormwood (artemisia absinthium l.) were e...
