Abstract:
... Experiments have been carried out to determine the growth characteristics of somatic embryogenic cell-derived bulblets (EB) in greenhouse. Embryogenic cells were induced from the bulb scales of Lilium Oriental hybrid 'Casablanca' in MS agar medium supplemented with 2 mg L‑1 picloram and 0.5 mg L‑1 BA and proliferated in 5-L bioreactor. Micro bulblets were produced from the cells in a regeneration ...

Abstract:
... Green lily (Lilium fargesii) is an endemic rare species in China, which seldom distributed in Mts. Qinling and Bashan, with narrow distribution and scarce population. The seed germination rate is 13.3%, which is not affected by storage temperature significantly. Meanwhile, the plug germination rate is 2.7%, which is probably limited to the maturity of seeds themself. The differentiation rate of bu ...

Abstract:
... Lengthy generation times in herbaceous perennials (1 to 5-10+ years from seed to flowering) impede the rate of progress flower breeders can make during breeding and/or domestication of floricultural crops. Geophytic herbaceous perennials, i.e., those with over-wintering underground storage organs (rhizomes, bulbs, corms, tubers etc.), have the added complication of the need for meristem size for v ...
