“…However, tissue source was significantly correlated with the status of regenerated bulblets Commercially grown ornamental geophytes are propagated by vegetative means to maintain genetic purity [4,5,22]. For conventional commercial vegetative propagation of lily, bulblets are produced from scales [12,29]. An efficient scaling technique consists of detaching the bulb scales and culturing them in moist and warm conditions for several weeks, during which internal and external factors cooperate to promote the formation of bulblets.…”

“…Intriguingly, we found that both the quantity and quality of bulblets were significantly positively correlated with scale FA (Figure 4b). Previous research reported that the ability to form bulblets was closely related to the position of the single scale on the bulb [9,14,29,33,34]. It is generally believed that OS and MS have stronger reproductive ability [13,32], because IS has relatively small BA and weak accumulation of nutrients, which cannot provide sufficient energy for the differentiation of bulblets during scaling.…”

“…Light treatment influences the morphogenesis of bulblets, but the results of previous studies vary [29]. To date, much attention has been given to the effects of light treatment on bulblet regeneration under in vitro conditions [34,[52][53][54], whereas research on light during scale propagation is still limited.…”

Scaling is the most commonly used technique to artificially propagate lilies. Scales from different positions of the donor bulb vary in regeneration efficiency; however, the mechanism underlying bulblet formation remains unclear. To investigate the relationship between scale morphological characteristics, initial nutrient status and bulblet regeneration capacities during scale propagation of Lilium, we performed comprehensive morphological and correlation analyses using scales from three lily cultivars. Principal component analysis clearly distinguished middle scale (MS) from outer scale (OS) by morphological characteristics alone. Morphological results indicated that MS and OS differ significantly in terms of scale width, facial area, basal area, volume, length-to-width ratio and width-to-thickness ratio. Correlation analysis showed that scale width was significantly positively correlated with both the quantity and quality of regenerated bulblets. Among the cultivars, starch and soluble sugars accounted for 50–80% of scale DW. And a higher initial ratio of sucrose to starch in scales was more conducive to the bulblets formation. Although light had no effect on the incidence of bulblets, the formation of bulblets was positively enhanced, and better morphological consistency was obtained. This present study achieved a comprehensive morphological and nutritional analysis focused on bulblet formation capacities of scales from different positions of lily bulbs via scaling propagation, laying a foundation for future molecular studies on bulblet formation.

“…On a mass scale, lilies are propagated vegetatively from bulb scales (Tang et al, 2020). The formation process and yield of bulblets are mainly influenced by environmental factors, growth regulators, and biostimulants (Sochacki et al, 2018;Gioi et al, 2019, Li et al, 2023.…”

Salinity occurring in intensively used agricultural, industrialized, and urbanized areas is one of the main factors in soil degradation. The effect of silver nanoparticles (AgNPs) on plant growth under environmental stresses is still not fully understood. Two experiments were conducted on the response of Asiatic lilies to treatment with colloidal AgNPs. In Experiment I, the study aimed to evaluate the effect of treating 'Osasco' lily bulbs with colloidal AgNPs (0, 25, 50, 100, and 150 ppm) on growth, flowering, and bulb yield, as well as the production of bulblets. Compared with the control, the applied colloidal AgNPs at all concentrations caused an acceleration of flowering and an increase in bulb diameter and the fresh weight of the aboveground part of the plants and bulbs. In addition, treatment with colloidal AgNPs at concentrations of 100 and 150 ppm increased bulblets' number and fresh weight. In Experiment II, the effects of colloidal AgNPs (100 ppm) and NaCl stress (600 mM) on the growth parameters, assimilation pigment content, and chemical composition of 'Bright Pixi' lily leaves were evaluated. As a result of the application of colloidal AgNPs, plants flowered faster and had increased height, petal width, fresh bulb weight, bulb diameter, and several scales in the bulb. Under NaCl stress, plants had reduced fresh weight of the aboveground part and bulb, bulb diameter, number of scales in a bulb, and contents of assimilation pigments, N, K, Ca, Cu, Mn and Zn. Colloidal AgNPs offset the adverse effects of salinity on bulb yield by increasing fresh bulb, bulb diameter, and the number of scales in lily bulbs. In conclusion, using colloidal AgNPs can contribute to developing new methods of bulbous plants production and an effective strategy to protect plants from everincreasing land salinization.
