Lilium longiflorum (Easter lily) vegetative propagation occurs through production of underground bulbs containing apical and axillary meristems. In addition, sexual reproduction is achieved by flowering of elongated shoots above the bulb. It is generally accepted that L. longiflorum has an obligatory requirement for vernalisation and that long day (LD) regime hastens flowering. However, the effect of bulb size and origin, with respect to axillary or apical meristems on flowering, as well as the interactions between these meristems are largely unknown. The aim of this study was to explore the effect of bulb size, vernalisation and photoperiod on L. longiflorum flowering. To this end, we applied vernalisation and photoperiod treatments to the different bulb sizes and used a system of constant ambient temperature of 25 °C, above vernalisation spectrum, to avoid cold-dependent floral induction during plant growth. Vernalisation and LD hasten flowering in all bulbs. Large, non-vernalised bulbs invariably remained at a vegetative stage. However, small non-vernalised bulbs flowered under LD conditions. These results demonstrate for the first time that cold exposure is not an obligatory prerequisite for L. longiflorum flowering, and that an alternative flowering pathway can bypass vernalisation in small bulbs. We suggest that apical dominance interactions determine the distinct flowering pathways of the apical and axillary meristems. Similar floral induction is achieved in propagated bulblets from scaling. These innovative findings in the field of geophyte floral induction represent valuable applicative knowledge for lily production.

“…A bulbil is an asexual reproductive organ of specific Lilium species; this organ is generated from leaf axils during flowering and is commonly used to produce cut flowers . Similar to bulb scales, bulbils from L. lancifolium are popular vegetable ingredients of stews and simmered soups in China.…”

Lilium lancifolium is an important edible starch plant that is widely cultivated in China. Bulbs and bulbils are starch storage organs of L. lancifolium found below and above ground. To further utilize lily starch resources, starches were extracted from bulbs and bulbils of L. lancifolium. The morphological, structural, thermal, hydrolytic, and in vitro digestive properties of these starches were systematically investigated and compared. The bulb and bulbil starches differed in their amylose content and granule size, as well as their shape and surface morphologies. Compared with bulbil starch, bulb starch had a relatively higher degree of crystallinity. The ordered structure in the external granule region of bulb starch was similar to that of bulbil starch. In addition, bulb starch demonstrated significantly higher solubility, onset temperature, and gelatinization enthalpy than bulbil starch. When hydrolyzed by α‐amylase and hydrochloric acid, bulb starch exhibited stronger resistance to enzymolysis but had a higher degree of acidolysis than bulbil starch. In vitro digestion showed that native and gelatinized bulb starches contained lower slowly digestible starch (SDS) content and higher resistant starch (RS) content than bulbil starch. In retrograded starch, bulbs and bulbils had similar amounts of rapidly digestible starch, SDS, and RS. This study sufficiently described the morphological and physicochemical properties of bulb and bulbil starches from L. lancifolium. This information is crucial to the future application of these starches in the food and nonfood industries.

“…This will result in efficient propagation, because lily bulbs have the capacity to regenerate bulblets at the base of their excised scale ( Figure 3B). Many studied have aimed to enhance some physiological traits of lily bulblets by regenerating the bulblets in vitro, including biomass production, repressing dormancy induction and stimulating phase change, (Bonnier and Van Tuyl 1997;Langens-Gerrits et al 1997;Langens-Gerrits 2003;Suh and Roh 2014;Gerrits and de Klerk 1992;Jásik and de Klerk 2006;Askari et al 2016).…”

“…Such ectopic shoot buds are called bulbils when located above ground and bulblets when regenerated below ground (Suh and Roh 2014). Natural regeneration methods include the formation of bulblets in the axil of the leaves, adventitious formation of bulblets along the proximal side of the stem and adventitious formation from the roots of the bulb.…”
