“…Besides, the karyotype was also described, indicating that P. australis has an asymmetric karyotype with haploid form 2m + 4sm + 2st. On the other hand, Schiappacasse et al (2005) reported different types of sexual and asexual propagation in different geophytes plants from Chile, including P. australis. With respect to genetic variation, no studies have been informed in this species.…”

“…It is known that seed germination over 85% of L. coquimbensis and L. purpurea happens at 10°C (De la Cuadra et al, 2002;Jara et al, 2006); for L. coquimbensis, L. purpurea, and L. ixioides germination is near zero at 20°C (Schiappacasse et al, 2005); and in L. purpurea, seed germination is totally inhibited at 25°C (Jara et al, 2006). Although optimal germination temperature is unknown, the studies above indicate that temperatures at or above 20°C inhibit germination and at 10°C germination is enhanced.…”

Leucocoryne is a Chilean endemic genus from the Amaryllidaceae family. It is an emerging crop with some registered varieties, currently oriented to a niche ornamental market. In the present work, seed germination in Leucocoryne dimorphopetala, Leucocoryne coquimbensis, Leucocoryne purpurea, Leucocoryne aff. vittata, Leucocoryne aff. violacescens, and Leucocoryne ixioides for seeds stored for 4 months and in L. purpurea, Leucocoryne vittata, L. aff. vittata, and L. ixioides for seeds stored for up to 16 months was analyzed at 10, 15, 20, or 25 °C. Germination data were analyzed by the previously developed time-germination model p = A{1 − exp[−k(t − t0)]}. Each germination curve had a coefficient of determination (R2) higher than 0.89, except when there was lack of germination. Results show that higher germination was better achieved at lower (10 or 15 °C) rather than at the higher temperatures (20 or 25 °C). When comparing germination results at temperatures of 10 and 15 with results at 20 °C, germination decreased by at least 30% and became near zero at 25 °C in seed stored for 4 months. Similarly when seeds were stored for 16 months, germination decreased by ≈20% at 20 °C, and again was near zero for germination at 25 °C. These germination habits of Leucocoryne are interpreted as an adaptive strategy to its natural habitats. In addition, L. dimorphopetala presents a type of dormancy and other species (L. purpurea, L. ixioides, and L. aff. vittata) may be sensitive to after-ripening changes during storage.

“…lahue, it would be feasible to increase the number of bulbils through methods of artifi cial vegetative multiplication such as bisection (Schiappacasse et al, 2003) or in vitro cultivation. Alternatively, propagation could be performed by seeds, which may reach high percentages of germination (89 to 100%) at 15 or 20ºC (Schiappacasse et al, 2003(Schiappacasse et al, , 2005.…”

“…lahue is a bulbous plant with ornamental potential because of its attractive foliage -similar to small palm leaves -and its delicate colorful fl owers, which have the appearance of small irises (Figure 2) (Hoffmann, 1989;Bridgen et al, 2002;Schiappacasse et al, 2003). The fl owering season, foliage permanence, vegetative propagation and seed propagation of "lahue" have been previously studied (Schiappacasse et al, 2003(Schiappacasse et al, , 2005. 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.…”

Effect of bulb weight on the growth and flowering of Herbertia lahue subsp. lahue (Iridaceae)

et al. 2009

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.
