Somaclonal variation has become common for many plant species including soybean (Glycine max (L.) Merr). The present study was aimed to compare the morphological and yield characters of tissue culture derived and field grown soybean cultivar CO-3 (Coimbatore-3). With respect to the plants derived from tissue culture, the morphological characters such as length of roots, shoots, petioles, intern...

Plant tissue culture comprises a set of in vitro techniques, methods and strategies that are part of the group of technologies called plant biotechnology. Tissue culture has been exploited to create genetic variability from which crop plants can be improved, to improve the state of health of the planted material and to increase the number of desirable germplasms available to the plant breeder. ...

plant tissue culture techniques were used to study the effect of nacl on tropane alkaloids accumulation and proline content of both datura metel and datura stramonium. callus cultures were established for both datura species. however, ms medium supplemented with 1mg/l of both ba and naa was the best for callus production in d. metel, while ms supplemented with 3 mg/l kin and 1 mg/l 2, 4-d was t...

The aim of this investigation was micropropagation of Quercus brantii L. via culture of terminal and lateral buds for mass production of this plant. The plant materials were collected from Fars province Iran in spring and summer seasons. After surface sterilization and the removal of phenol materials from the explants, they were transferred into different culture media containing different conc...

Salinity considered as significant ecological regarding the productivity of different crops different arid and semiarid areas all over the world. The most damaging things of salinity on herbal are usually related with low osmotic potential of soil solution, nutritional imbalance etc. Improving several plants usually happens under saline circumstances as a method for using saline soils which are...

The identification of a widespread contaminant of plant cell cultures is reported. Mycobacterium scr~luhtceum Prissick and Masson appears as yellow colonies on the medium and plant tissues of many ornamentals being propagated in vitro. It is a Gram positive and acid fast bacterium and requires a specifically formulated medium for growth in pure culture. Many laboratories have alluded to this co...

Growth and morphogenesis of in vitro cultures of plant cells, tissues, and organs are greatly influenced by the composition of the culture medium. Mineral nutrients are necessary for the growth and development of plants. Several morpho-physiological disorders such as hooked leaves, hyperhydricity, fasciation, and shoot tip necrosis are often associated with the concentration of inorganic nutrie...

For the last 50 years, scientists have recognized that varying ratios of the plant hormones cytokinin and auxin induce plant cells to form particular tissues: undifferentiated calli, shoot structures, root structures, or a whole plant. Proliferation of undifferentiated callus tissue, greening, and the formation of shoot structures are all cytokinin-dependent processes. Habituation refers to a n...

Tissue culture is useful method for large scale production of healthy corms and also avenues for creating variability through in vitro use of mutagens and polyploidizing agents. Induction of callus and subsequent regeneration of plants is suggested as possible means of introducing new variation. In vitro micropopagation for product formation its utility is increasing the amount of crocin, picro...

Supercoiled mitochondrial DNA (mtDNA) has been isolated in preparative amounts from five different plant species and compared on agarose gels. The gels reveal considerable mtDNA size heterogeneity within each species as well as substantial differences in the range and frequency of the mtDNA size classes among the different plants. The two lowest size classes of three of the plants have been ext...
