| Popis: | Micropropagation of Lycium barbarum cv. 'Ningxia N1' was achieved. The cultures were by initiated by axenical seed germination. The highest shoot proliferation was obtained on the MS media with 1.33 or 2.22 µM benzyl adenine, gelled with wheat starch as an agar alternative. The treatments with 2.22 µM benzyl adenine ensured proliferation rates superior to the ones with 1.33 μM benzyl adenine, but the latter provided longer and more robust shoots. Use of large microcuttings as an explant onto the multiplication media ensured higher in vitro explant survival, higher number of shoots regeneration and more vigorous plantlets. The microcuttings inserted vertically into the media yielded superior growth and multiplication as compared to the microcuttings placed horizontally. The non-rooted, elongated shoots from the treatment 1.33 μM benzyl adenine were either rooted in vitro on a hormone-free MS medium with starch or used for direct ex vitro rooting and acclimatization. The optimal number of microcuttings/vessel for in vitro rooting was 40 and the rooted plantlets were efficiently acclimatized ex vitro by three methods: float hydroculture in floating cell trays, floating perlite, and in Jiffy7 pellets. |
