“…It is important to highlight, however, that all the bulbs planted, regardless of their weight in the fi rst season, will be able to produce fl owers in the second and subsequent seasons. These results are consistent with those obtained for other geophytes that grow in the coastal desertic and semidesertic zones of Chile (Kim et al, 1998a, b;Yañez et al, 2005), and for "huilli" from Coquimbo (Leucocoryne coquimbensis), a plant of perennial bulbous habit that grows in the coastal desertic and semidesertic zones of Chile (Kim et al, 1998b).…”

“…However, it is necessary to optimize crop management, and specifi cally, to know the effect of bulb weight on the fl owering and multiplicative capacity of this species. The scarce investigations that have already been carried out on Chilean geophytic plants agree with investigations on commercial species, which have demonstrated that bulbs with a minimum size are required for blooming and the production of high quality fl owers (Kim et al, 1998a, b;Yañez et al, 2005). That is, starting from a specifi c minimum size, bulbs bloom and produce a large number of fl owers per infl orescence, a large number of fl oral stems, and long stems and fl oral pieces (Halevy, 1990).…”

Bulb weight or size is one of the critical factors affecting the vegetative growth and fl owering of bulbous species. This study assessed the effect of bulb weight on the growth and fl owering of Herbertia lahue subsp. lahue. This bulbous species, commonly known as "lahue," has the potential to be used as an ornamental plant. Lahue bulbs were collected during their dormant period from Tregualemu (Región del Maule), grouped by weight categories and planted in Talca in an unheated polyethylene greenhouse. Phenology data, fl owering characteristics and the number of newly formed bulbs were recorded for one season. Plants emerged 2-3 weeks after planting and fl owered during the spring, between 8 and 9 months after planting. During fruit set, the leaves began their senescence process and reached dormancy during the summer. Lahue behaved as a typical geophyte adapted to a seasonal climate such as the Mediterranean climate of Central Chile. Bulbs weighing 0.35 g or more were able to fl ower. However, bulbs greater than 0.75 g produced more and better quality fl owers. The average multiplication rate of the bulbs was 1-1.13 bulblets per planted bulb, regardless of the bulb weight; there was no correlation between multiplication rate and bulb weight. This study demonstrated that it is possible to grow lahue as a pot plant or garden plant and that the size of the bulb will determine if fl owering can be achieved.

“…In nature, Z. elegans usually grows in sandy soil (Yáñez et al, 2005). It has been described as having a high potential as an ornamental crop because of its light blue to blue flowers and growth habit (Bridgen et al, 2002;Kim and Ohkawa, 2001;Kim et al, 1997).…”

“…It has been described as having a high potential as an ornamental crop because of its light blue to blue flowers and growth habit (Bridgen et al, 2002;Kim and Ohkawa, 2001;Kim et al, 1997). Z. elegans produces only one daughter corm after the growing season, making natural vegetative propagation difficult to achieve (Yáñez, 2005). Although seed propagation may cause variability, it is currently the only method to obtain a large number of plants.…”

Decreased time from seed to flowering corm size in Zephyra elegansvia in vitro cultivation

2012

577-584. Experiments were performed to establish a method to reduce the time from seed to flowering in Zephyra elegans. Seedlings took at least four years to produce a flowering corm. Although germination was highest in a water-agar medium, plant necrosis occurred when plants were later transferred; therefore, MS (Murashige and Skoog) medium was selected as the medium for germination. An increase in the light intensity to 9500 lux and in the pH to 6.7, significantly increased the germination rate. Eight weeks after seed germination, seedlings were transferred to MS media with sucrose concentrations of 45, 60, 75, 90 or 105 g L -1 and a pH 5.7 or 6.7, with the aim of achieving the greatest corm weight gain. After 16 weeks, the best weight gain was obtained in the MS medium with 75 g L -1 of sucrose and a pH of 6.7. The resulting corms were transferred to pots and grown under greenhouse conditions. Corms weighing under 0.12 g did not sprout, whereas all corms over 0.3 g sprouted and all those over 0.4 g at the end of the in vitro culture stage bloomed in the second year of greenhouse cultivation. The time required for development from seedling to flowering corm was reduced to two years.
