摘要：
Lilium Asiatic hybrid 'Mona' bulblets were cultured in vitro for 100 d under photoautotrophic (CO2-enriched conditions and without sucrose in the medium) and heterotrophic (non-enriched CO2 conditions and sucrose-supplemented medium) methods and under various levels of photosynthetic photon flux (PPF). Bulblet growth and net photosynthetic rate (NPR) were analyzed. CO2- and PPF-enriched conditions enhanced the overall growth of bulblets, scale leaves, and roots. Heterotrophic conditions enhanced bulblet growth but higher PPF levels were inhibitory to the development of scale leaves. These results indicate the CO2- and PPF-enriched conditions (photoautotrophic conditions) are beneficial for the production of high-quality bulblets of Asiatic hybrid lilies in vitro.
