Three Andean tetraploid potato genotypes (2n=48) and 7 anther-derived dihaploids (2n=24) originating from two of the tetraploids were used in anther culture. Relative number of embryos/vial was significantly higher when the anther culture media was g

The effects of activated charcoal and organic substances on embryogenesis in anther cultures of Anemone canadensis L. were studied. Embryogenesis was independent of the presence in the culture medium of glycine, nicotinic acid, pyridoxine, thiamine,

PURPOSE: To evaluate whether MRI signal and T2* measurements of lung tissue acquired at ultrashort detection times (tds) can detect emphysematous changes in lungs.MATERIALS AND METHODS: MR signal intensity of in vivo mouse lungs was measured at 4.7 T

Media composition in anther cultures has been extensively studied over the years, leaving research concerning the effect of gelling agents somewhat behind. Agar has traditionally been the most common gelling agent being both cheap and easily availabl

A new method is presented for anther culture. Anthers are cultivated on cubes of solid medium, surrounded by liquid medium. This allows changes of media composition at any time. When embryos or callus were produced, the liquid initiation medium was r

Out of 20 tetraploid clones, 19 produced embryoids in anther cultures incubated on doublelayer medium containing activated charcoal. More than 90% of the plants derived from such embryoids have been shown to be dihaploid. Effects on embryogenesis of

Four tetraploid potato genotypes (194.10, 199.13, 201.5, 201.12) were examined in anther culture. The androgenic responses were in general high. Cv. 199.13 contributed with the best response, varying between 0.38 and 0.55 embryoids per anther. Gellan
