61 WORKSHOP 1 (Abstr. 1020-1035) Efficient Use of Minerals to Produce High Yield and Optimum Quality Fruit, Vegetables, and Ornamentals
Man's breeding and selection of woody ornamentals is, by no stretch of the imagination, a novel pursuit, but has employed succeeding generations of plantsmen for many centuries. Currently, selection of woody ornamentals that depends on government or industry funding is inevitably stimulated by cultural or disease problems with existing species or cultivars, by changing consumer needs, or by recognition of a market demand for superior or novel plants. The worth of this work frequently is judged in terms of its potential economic benefit. Speculative breeding and/or selection of esoteric plants, a traditional pursuit of the enthusiastic horticulturist, is now difficult for anyone other than the keen amateur to sustain.
Floriculture & Ornamentals
greening performance differ with the choice of plant species and vary seasonally. Therefore, the objective of this study was to investigate the cooling performances of EGRs planted with different ornamental species overall four seasons. Since previous
nursery containers, many weed species can reduce ornamental crop growth by ≥60% and lead to an increase in production time ( Berchielli-Robertson et al., 1990 ). Although not all weed species are competitive with ornamentals, weed presence thresholds
The “Reseau d' Essai de Plantes Ligneuses Ornementales du Québec” (REPLOQ) is a research project created in 1982 with a principal mandate to elaborate, develop, and coordinate with specialists on a cooperative research project to evaluate the winter hardiness of ornamental plants throughout the province of Quebec.
Root hardiness of numerous woody ornamentals was determined after artificial acclimation. In the species tested, the killing temperatures of young roots ranged from -3° to -11°C while that of mature roots ranged from -8° to -23°. The relative hardiness of young roots was not necessarily indicative of the relative hardiness of mature roots.
