Potencial ornamental de Baccharis milleflora e Baccharis tridentatacomo folhagem de corte

Abstract

RESUMO: A prospecção de novas plantas ornamentais a partir de espécies nativas amplia a oferta de produtos para o mercado da floricultura. Entretanto, antes de uma espécie ser indicada como ornamental, suas características estéticas devem ser avaliadas pelo público consumidor. Com isso, o objetivo deste estudo foi prospectar novas plantas para uso como folhagem de corte e avaliar o seu potencial ornamental. O potencial ornamental das espécies prospectadas foi avaliado por 10 profissionais especialistas em arte floral, com base em metodologia que considera características qualitativas e quantitativas de importância ornamental para o mercado consumidor. Cada critério foi pontuado por meio de notas de dez (mínima) a 100 (máxima). Baccharis milleflora e Baccharis tridentata foram selecionadas na região de Mata Atlântica, em borda de mata, por apresentarem ocorrência frequente na paisagem, hastes longas, folhas exuberantes, com coloração destacada na paisagem e aspecto aparentemente rústico. Ambas as espécies apresentam alto potencial ornamental para uso como folhagem de corte com características adequadas para o uso como complementos para arranjos florais.

Ornamental potential of sweet potato accessions

“…Villagra et al (2011), who stated that leaf shape is one of the most important traits for genotypic distinction. Based on Tognon et al (2015), the leaf shape is one of the most relevant elements in arrangements composition since it gives the idea of movement, transmits smoothness (rounded leaves), or even demonstrates aggressiveness (pointy leaves). Leaf size is equally significant in floral arrangements.…”

“…1). The presence of genetic variability is of great interest since it increases ornamentation usage options (TOGNON, 2015). Additionally, Pietro et al (2012) reported that the green coloration of the species promotes certain lightness to the arrangement.…”

“…Sweet potato presents some traits of ornamental interest, including the absence of aroma, which is expected from the ornamental foliage that composes an arrangement. The lack of aroma is fundamental to avoid interference on the fragrance exhaled by the flowers that compose the arrangement (TOGNON et al, 2015).…”

Field trial survey and breeder perceptions to select between ornamentalGlandulariahybrids

“…Hundreds of species of many botanical families used intensively in commercial floriculture and garden plants and traded commercially as ornamentals (Heywood, 2001). The success of the new floricultural products in the market can be increased if the ornamental desirable traits were determined by specific criteria (Stumpf et al, 2007), such as the morphological characteristics of the plant, as regard to its novelty or aesthetic value (Tognon and Cuquel, 2016). A better understanding of consumers' preferences for native plants, their attitudes toward bringing a more naturalistic landscape design and the assessment of their purchase behaviour may allow a better characterization of the market for producers of native plants (Nils Peterson et al, 2012;Alam et al, 2017).…”
