“…Según Wang y Breen (1986), en Lilium las yemas florales expresan una alta dependencia de los órganos fuente, probablemente correlacionada con el incremento en el crecimiento de los tejidos florales (Clement et al, 1996). Esto explica la correlación entre la masa seca de flores y de hojas (-0,68; tabla 2), que además indica que existe translocación de fotoasimilados de las hojas a las flores para que garanticen su normal desarrollo.…”

La temperatura de vernalización en bulbos reutilizados de lirio (Lilium sp.) afecta la distribución de materia seca y la producción de flor RESUMENEl lirio se propaga comercialmente mediante bulbos. Para los programas de siembra en Colombia, los bulbos deben ser importados, pero tienen un alto costo, lo cual reduce la rentabilidad del cultivo. No obstante, mediante la vernalización de los bulbos que quedan después del corte de la flor es posible obtener nuevas cosechas. Por tanto, el objetivo fue evaluar el efecto de diferentes temperaturas de vernalización en bulbos reutilizados de lirio del híbrido asiático Castello sobre la distribución de materia seca y calidad de la flor. Se utilizó un diseño completamente al azar con cuatro tratamientos correspondientes a tres temperaturas de vernalización (-2°C, 3°C y 14ºC) y un testigo comercial (bulbos importados), cada tratamiento tuvo tres repeticiones. Los bulbos fueron almacenados durante 8 semanas a las temperaturas mencionadas y luego fueron sembrados en campo. El testigo comercial generó mayor masa seca de flores, tallo, bulbo y total, y mejor calidad de flor, con la vernalización a -2°C y 3°C se obtuvo una moderada masa seca de flores, tallo y total pero baja en bulbos, se presentó alta floración y buena calidad de flor de lirio, mientras que con 14°C no se presentó una removilización adecuada de las reservas del bulbo, lo que afectó negativamente el crecimiento y la floración. La vernalización de bulbos reutilizados de lirio es una práctica que potencialmente podría reemplazar la importación de bulbos, pero necesita más investigación para aumentar su eficiencia. ABSTRACTLily is propagated commercially with bulbs. For planting programs in Colombia, these bulbs must be imported, but this is an expensive procedure, which reduces profitability. However, through vernalization of bulbs that remain after cutting the flower, it is possible to obtain a new crop cycle. Therefore, the objective was to evaluate the effect of different temperatures in the vernalization of reutilized lily bulbs of the Asian hybrid Castello on the distribution of dry matter and flower quality. A completely randomized design was used with four treatments for three vernalization temperatures (-2°C, 3°C y 14ºC) and a commercial control (imported bulbs), each treatment had three replications. The bulbs were stored for 8 weeks at the above-mentioned temperatures and then planted in the field. The commercial control produced greater dry mass for: flowers, stem, bulb and total; and better quality of flowers. With vernalization at -2°C and 3°C, a moderate dry mass for flowers, stems and bulbs was obtained, but with a low total dry mass; whereas lilies at these low temperatures bloomed abundantly and presented good quality flowers. At 14°C, no adequate remobilization of reserves of the bulbs took place, which negatively affected growth and flowering. Vernalization of reutilized lily bulbs is a practice that potentially could replace bulb imports, but more research needs to increase its efficiency.

“…In fact, Dantuluri and Misra (2002) demonstrated that removing the flowering structures of Asiatic Lily increased carbon supply to economically important yield components. Removing the flower buds of Easter Lily increased carbon supply to the bulb (Wang and Breen, 1986). Flower removal in soybean has also been shown to increase total dry matter content of the plant (Heitholt and Egli, 1985).…”

Field experiments conducted in 2002 and 2003 evaluated the effects of timing of inflorescence removal on propagule formation, growth and development of Astilbe ×arendsii, Hemerocallis spp. and Hosta spp. Four timings of inflorescence removal were tested: 1) no removal (control), 2) removal at inflorescence emergence, 3) removal at preflower, and 4) Removal at full flower. Propagule formation in Astilbe was not enhanced by inflorescence removal. Hemerocallis plants with their inflorescences removed at emergence produced 25% more divisions than plants with their inflorescences removed at preflower. For Hosta, plants with inflorescences removed at pre- and full flower produced respectively 40% and 53% more divisions than control plants. These results have economic implications for commercial bare-root production, which need to be verified on a larger field scale.

“…: See footnote of Table 1. 18 and 'Star Gazer' (an oriental lily) 15 , the sink activity of flowers before anthesis was very high and bulb scales were markedly competitive with flowers as a sink. This dominant DM accumulation in the flower buds and bulb between the visible bud stage and flowering stage was also observed in the experiments (Fig.…”

Abstract'Siberia' Oriental hybrid lily plants were grown under conditions of changing day temperature (DT) and night temperature (NT). Plants were grown under three fluctuating temperature conditions (average 25.8°C, 23.4°C, and 19.9°C) in a temperature gradient growth chamber (TGC), and under three DT/NT levels (28/23°C, 24/19°C, and 20/15°C) in constant temperature growth chambers (CGCs). In the CGC experiment, 35 days after planting (at the visible bud stage), the plants grown under low temperature conditions had high fresh weight (FW) of the stem and stem roots. At the flowering stage in both TGC and CGC experiments, the plants grown under low temperature conditions had a longer stem length and higher FW of the stem, flower buds, stem roots, and bulb compared than those of plants grown under high temperature conditions. The plants grown under low temperature conditions had high dry weight (DW) of the total plant, stem, and bulb, and a high DW/FW ratio of the stem and bulb. In both TGC and CGC experiments, the plants grown under the low temperature conditions showed a high relative growth rate (RGR) and net assimilation rate (NAR) from planting to flowering. These data demonstrate that cooler growing temperatures are advantageous for the accumulation of dry matter in 'Siberia' lilies. The low growing temperature enhances the accumulation of dry matter in 'Siberia' lily plants via the promotion of photosynthesis by leaves and the absorption of nutrients by well-developed stem roots.
