Abstract

Abstract Brazilian floriculture is driven by novelties, requiring the constant entry of new products into the market. This situation favors Brazil, which has, in its native flora, unique species in the world and with high potential for rational use for commercial purposes. The Brazilian flora with ornamental potential is little explored, and the use of species is restricted and, often, extractive with consequent genetic erosion. The use of native species from different ecosystems may constitute a future alternative of products for Brazilian floriculture. Despite the large amount of plant genetic resources, there are few initiatives for the conservation and domestication of species and improvement for sustainable use. For this reason, the Brazilian Agricultural Research Corporation (Embrapa) conserves collections of ornamental plants, and the research initiatives of these collections form the Genetic Resources of Ornamental Plants Project. In addition to conservation, it sought, in partnership with other institutions, the characterization and evaluation of the potential use of these species aiming at the completion of products for floriculture. In this way, the materials already characterized and documented make it possible to add value to genetic resources, already maintained. Currently, Embrapa has six ex situ collections of ornamental plants (Tropical species, Bromeliads, Cactaceae and species from the Pampa Biome, Amazonian Orchids and species from Cerrado) and also counts on the genetic variability of banks of other products (Passion fruit, Pineapple, Paspalum, Pepper, Pumpkin germplasm banks) that have been evaluating accessions, selecting and registering cultivars for ornamental use.

巴西Embrapa种质库中的巴西观赏植物遗传资源：障碍与机遇

摘要巴西花卉文化是由新奇事物驱动的，需要不断有新产品进入市场。这种情况有利于巴西，在其本土植物群中，巴西拥有世界上独特的物种，具有很高的商业合理利用潜力。具有观赏潜力的巴西植物群很少被探索，物种的使用受到限制，而且往往是提取的，从而导致遗传侵蚀。使用来自不同生态系统的本地物种可能构成巴西花卉栽培产品的未来替代品。尽管有大量的植物遗传资源，但很少有保护和驯化物种以及改善可持续利用的举措。因此，巴西农业研究公司（Embrapa）保护观赏植物的收藏，这些收藏的研究举措形成了观赏植物遗传资源项目。除了保护外，它还与其他机构合作，寻求对这些物种的潜在用途进行表征和评估，以完成花卉栽培产品。通过这种方式，已经表征和记录的材料有可能为已经保存的遗传资源增加价值。目前，Embrapa有六个非原位观赏植物集合（热带物种、凤梨目、仙人掌科和潘帕生物群落的物种、亚马逊兰花和塞拉多的物种），还依靠其他产品库（百香果、菠萝、Paspalum、胡椒、南瓜种质库）的遗传变异性对材料进行评估，选择和登记供观赏的品种。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
