Commercial producers of herbaceous ornamentals have reported that long-day plants sometimes flower under short-day conditions when the photosynthetic daily light integral (DLI) is high, but little research-based information available to support phenomenon. We grew seedlings tickseed (Coreopsis grandiflora), echinacea (Echinacea × hybrida), lavender (Lavandula angustifolia), lobelia (Lobelia spe...

Interest in the sustainability of farming practices has increased in response to environmental problems associated with conventional agricultural management often adopted for the production of herbaceous crops, ornamentals, and fruit crops. Availability of measures of the status of the soil ecosystem is of immediate importance, particularly for environmental assessment and monitoring programs. ...

Intensity and type of management, the cultural variable shade, and the combination of woody and herbaceous annual and perennial plants were evaluated for their effect on key landscape arthropod pests. Azalea lace bugs, Stephanitis pyrioides (Scott), and twolined spittlebugs, Prosapia bicincta (Say), were most effectively suppressed in landscape designed with resistant plant species of woody orn...

This study was conducted to evaluate the growth, visual quality, and stress response of 17 species of bedding plants andKentucky bluegrass (Poa pratensisL.) grown outdoors for 10 weeks during the summer of 2003 at three locations in Colorado. Plants were irrigated at 100% of the reference evapotranspiration (ET0) (amount required to maintain Kentucky bluegrass in an optimum condition) for 2 wee...

Meloidogyne hapla can be spread in bare-root herbaceous perennial propagation material and may be difficult to control once established in new fields or in the landscape. Root pruning of bare-root plants was investigated as a means of reducing spread and establishment of M. hapla. Plants previously inoculated with 10,000 eggs/plant were root-pruned to remove either a portion or most of the fibr...

Growth characteristics and marketing of woody ornamentals prevent crop scheduling common in floriculture crops. However, many tasks in the production of woody ornamentals require coordination with the season and/or physiological state of the species. Since most woody ornamental nurseries produce many species or cultivars, a variety of tasks occur concurrently. This review highlights the major t...

Many cultivars of ornamental conifers are difficult to propagate. Cuttings may root poorly and graft success may be highly variable even in the hands of skilled, experienced propagators. Because of these problems, we conducted a detailed study of the physiology of graft formation in Picea pungens 'Hoopsi' scions grafted on Picea abies rootstocks with the purpose of identifying factors limiting ...

The family Fabaceae (Leguminosae) is used as a starting point for creating a database of naturalized/ invasive plant taxa in Taiwan, a Pacific island with very limited available information on plant invasions. A comprehensive list of naturalized Fabaceae, with background information on origin, habit, life form, and minimum residence time for most of the species is presented. This family is the ...

Each region has its own floristic characteristics relative to geographical position. The specificity of the vegetation and particularities each flora require knowledge beekeeping determine forage supply for bees. Where, production in Fray Mamerto Esquiú department (Catamarca, Argentina) is based on diversity plant species place, composed native flora, natural forest different types crops (forag...
