The effect of soil amendment with degraded granite or perlite on plant growth of Ornithogalum thyrsoides were investigated in Central Chile. Bulbs were planted in April in raised soil beds under greenhouse. Three different substrates were compared: control (unamended soil); decomposed granite soil (DG) and soil in proportion 1:2; and perlite and so...
There is an increasing trend in Chile to establish green roofs in urban areas using native plants in order to reintroduce the lost flora in the cities. Most Chilean cities are located in the central zone, where mediterranean climate predominates with minimal rainfall during the hot summer period. Thus green roofs require an irrigation system to pro...
Chilean nurseries make important efforts to develop new native crops for landscaping, with emphasis on species suitable for wa-ter-saving conditions. Bromeliads are naturally adapted to low water soil conditions; the genus Puya is widely used as a garden plant. Worldwide, commercial bromeliads are forced to bloom by treating them with ethylene, eit...
Eremurus, commonly known as Foxtail lily, is a novel, commercially important specialty cut flower, but postharvest handling procedures need to be optimized for longest vase life. Cut inflorescences of ‘Line Dance’ and ‘Tap Dance’ eremurus were evaluated for optimal harvest stage, harvest procedures, effects of anti-ethylene agents, and storage meth...
Hydrangea macrophylla subsp. macrophylla var. macrophylla has been widely cultivated as a garden and potted plant. In addition, cut flower cultivars have been developed and have been recently introduced in Chile for export to the United States. Currently, cut flowers are air-shipped in cartons with their stems placed into individual water tubes. Th...
Eremurus is a striking specialty cut flower with high commercial potential, but postharvest handling procedures need to be optimized for longest vase life. Cut stems of ‘Line Dance’ and ‘Tap Dance’ eremurus were evaluated for optimal harvest stage, harvest procedures, ethylene sensitivity and effects of anti-ethylene agents, and storage methods and...
Eremurus is a popular ornamental geophyte, originated from Asia and used for cut flower production in regions with a temperate climate. The underground organs of the plant consist of tuberous roots and a corm-like crown with renewal buds. During the annual growth cycle, long period of low temperatures under 10°C is required for dormancy release and...
The taxonomy of Chilean Amaryllidaceae is confusing. Taxonomic problems still persist at the level of genera and species. Currently there is controversy about the correct classification of species so far assigned to Rhodophiala C.Presl. Through the study of morphological characters, recently has been suggested the rehabilitation of the genus Rhodol...
Carnations, Dianthus caryophyllus, have been cultivated in Chile for several decades as a cut flower crop. At the present time, floriculture occupies 2,124 ha, of which 180 ha are devoted to carnations. Almost all carnations produced are sold in the domestic market. Several diseases affect carnations, among them fairyring leaf spot (Cladosporium ec...

Bulb weight or size is one of the critical factors affecting the vegetative growth and flowering of bulbous species. This study assessed the effect of bulb weight on the growth and flowering of Herbaria lahue subsp. lahue. This bulbous species, commonly known as "lahue," has the potential to be used as an ornamental plant. Lahue bulbs were collecte...
P. Morales, F. Schiappacasse, P. Peñailillo, and P. Yañez. 2009. Effect of bulb weight on
growth and fl owering of Herbertia lahue subsp. lahue (Iridaceae). Cien. Inv. Agr. 36(2):259-
266. 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 weig...
Liatris spicata (L.) Willd. was introduced to Chile as a cut flower crop more than a decade ago. It is commonly field-planted in consecutive plantings during spring and summer. The propagation structure is a corm that is reused in subsequent plantings. Other field crops are shaded to reduce the temperature, but in liatris, the effect of shading und...
28 especie ornamental. Respecto de los ensayos en propagación vegetativa Los esquejes de las plantas madre se colectaron de individuos que mantenían la forma menos defectuosa con poca consistencia resinosa y bastante ramificadas, se seccionaron ramillas muy cerca de la base de la planta, sin terminaciones de capítulos florales con hojas escamiforme...

Lilium spp. hybrids are important export products among the Chilean cut flower exports. Field plantations are often shaded to reduce temperature; however, the best shading percentage to attain a good quality cut flower and also a good quality bulb is unknown. This study assessed the cut flower quality of two Lilium spp. hybrid cultivars, cv. Dreaml...
Los híbridos de Lilium spp. son importantes productos de exportación de la floricultura chilena. En cultivos al aire libre se suele sombrear para reducir la temperatura, sin embargo se desconoce el grado de sombreamiento adecuado para lograr buena calidad de varas florales y de bulbos. El presente estudio evaluó la calidad de las varas florales de...
Proteas have been introduced as new commercial crops during the last decade in Chile. The area where these species are cultivated has increased during recent years and is located between the V and VII Regions (approximately 33° South latitude and 35° South latitude). However, insects and diseases which could affect them, decreasing productivity and...
The endemic Chilean genus Conanthera belongs to the Tecophilaeaceae family and is distributed in the northern and central parts of Chile. This genus is formed of various species, all of which have a fibrous corm and beautiful blue, violet or white flowers of variable size and shape. These species could be used for ornamental purposes as pot or gard...
Chilean geophytes are distributed throughout the country, between Arica (18°29’ South latitude) and Tierra del Fuego (54°20’ South latitude). However, the greatest diversity is concentrated in the central part of the country, which has a Mediterranean climate. There are about 40 genera, and, depending on the species, they have a great potential eit...
