Effect of reused bulb vernalization on lily flower quality (Lilium sp.) in the Bogota Plateau ; Efecto de la vernalización de bulbos reutilizados sobre la calidad de la flor de lirio (Lilium sp.) en la Sabana de Bogotá

Lily production has lately acquired great importance in Colombia, but its expansion is limited by the high cost of the bulbs, which are imported, and only produce quality flowers in the first harvest. This determines the constant purchase of new material in order to keep up with the planting programs. However, vernalization of the bulbs that are left after flower cutting allows further production of good quality flowers. In this context, the aim of this study was to evaluate the effect of bulb vernalization on lily flower quality. Applying a completely randomized design, bulbs of Asian hybrid... Mehr ...

Lily production has lately acquired great importance in Colombia, but its expansion is limited by the high cost of the bulbs, which are imported, and only produce quality flowers in the first harvest. This determines the constant purchase of new material in order to keep up with the planting programs. However, vernalization of the bulbs that are left after flower cutting allows further production of good quality flowers. In this context, the aim of this study was to evaluate the effect of bulb vernalization on lily flower quality. Applying a completely randomized design, bulbs of Asian hybrid Castello were treated with 10 different combinations of vernalization times (4, 6 and 8 weeks) and temperatures (-2, 3 and 14°C), and compared to a commercial control (imported bulbs). The latter exhibited the best results, followed by the bulbs vernalized at 3°C for 8 weeks, which produced earlier ripening plants that bore less unopened flowers, super *3 buds and a higher percentage of extra quality flowers with longer vase life. These results reveal the importance of vernalization in lily production. ; En Colombia el cultivo de lirio ha adquirido gran importancia, pero su expansión está condicionada al costo elevado de los bulbos. El bulbo para producción de flor es importado; este produce flor de calidad solamente en la primera cosecha, por lo que el productor debe comprar nuevamente material para poder mantener sus programas de siembra. Sin embargo, con la vernalización del bulbo que queda después del corte de la flor se pueden obtener más flores de buena calidad. Por tanto, el objetivo del trabajo fue evaluar el efecto de la vernalización sobre la calidad de flor de lirio. Se utilizó un diseño completamente al azar. Se sometieron bulbos del híbrido asiático Castello a 10 tratamientos compuestos por la interacción de tres tiempos (4, 6 y 8 semanas) y tres temperaturas de vernalización (-2, 3 y 14°C) más un testigo comercial (bulbos importados). Este último fue el mejor tratamiento, seguido de la vernalización de bulbos ...
