salt stress negatively impacts crops yield throughout the world. nine varieties of potato (solanum tuberosum l.) were screened for salt stress tolerance by measuring in-vitro growth of the aerial plant parts, as well as roots. salt stress was evaluated by adding 25, 50, 75, 100, 125, 150 and 200 mm of nacl to murashige- skoog (ms) medium and compared to ms medium without nacl. plant length and ...
in this research the focus of the researcher is on the influence of american myths that have long been held and offered by the american culture and ideologies. sam shepard is conceived to be one of the greatest playwrights of the contemporary american theater. in his works he depicts broken characters who are struggling to keep up with the national expectations but are ceaselessly borne back to...
background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...
the aim of the present study was to develop an in vitro system for functional investigation of ovarian follicular cells in sterlet, acipenser ruthenus. oocytes for the primary culture were obtained from the ovaries of a 6 years old sterlet 729 g in weight and 47 cm in total length. the oocytes were in advanced vitellogenesis stage (pi >10). a part of the ovary (containing about 300 follicles) w...
scented rose species are very important in the genus rosa due to their use in highly-prized essential oil production and as garden roses. the fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. a comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly damask r...
Background: While assisted reproductive techniques (ARTs) are considered to be safe, many concerns exist about the safety of these techniques. Two important and indispensable parts of these techniques are in vitro culture and vitrification. While much progress has been made in developing culture conditions, it remains suboptimal. In order to investigate the effect of culture medium on in vitro ...
