Cultivo e uso de variedades crioulas de abóboras ornamentais no Rio Grande do Sul

Abstract

Production and use of ornamental pumpkin landraces in the Rio Grande do Sul State, BrazilLandraces of several cucurbit species are cultivated in Brazil. The greatest genetic diversity of cultivated Cucurbita seems to be found in Rio Grande do Sul State, where farmers have the knowledge and practice to store and exchange these seeds. Many of these varieties have potential for ornamental use. This research was developed to rescue the popular knowledge associated with the use and cultivation of landraces of ornamental pumpkins in Rio Grande do Sul State, Brazil. Farmers that donor landraces seeds to the Cucurbitaceae Active Germplasm Bank of Embrapa Temperate Agriculture were interviewed. A semi-structured questionnaire was used, with respondent identification (name, age, profession, gender, ethnicity and address) and guiding questions relating to knowledge about ornamental pumpkins (history of cultivation in the family, origin of the seed, popular name assigned, reasons to keep growing, planting time and harvest, the fruit selection criteria, ways to use, location and crop management, and ways of removing and storing seeds). We interviewed 12 farmers who donate the seeds for the Bank and, through them, nine other growers of ornamental pumpkin landraces were identified, which added three new accessions to the Bank. In conclusion, a relationship between the selections and their guardians was observed and a wide diversity of ornamental pumpkin landraces maintained by farmers in southern Rio Grande do Sul State was reported.

Caracterização morfológica de variedades crioulas de abóboras (Cucurbita maxima) do sul do Brasil

“…O Banco Ativo de Germoplasma (BAG) de Cucurbitáceas, da Embrapa Clima Temperado, conserva 640 acessos de diferentes espécies cultivadas dos gêneros Citrullus, Cucumis, Cucurbita, Lagenaria, Luffa, Momordica e Sicana, sendo que 85 acessos são variedades crioulas de Cucurbita maxima. Porém, apenas uma pequena parte do acervo total do BAG já foi caracterizada (Neitzke et al, 2009;Priori, 2011;Priori, 2015;Fischer, 2012;Fischer et al, 2015;Fischer et al, 2016;Priori et al, 2012;Priori et al, 2013;Priori, et al, 2017). Para a realização deste trabalho, nove variedades crioulas de C. maxima foram selecionadas, seguindo-se alguns critérios, como a quantidade de sementes disponíveis no BAG e suficientes para a implantação do experimento, os dados de passaporte (como local de coleta, características dos frutos, reveladas pelos agricultores que doaram as sementes, como formato, cor da casca e tamanho dos frutos).…”

Research Article Digital phenotyping of winter squash fruits

“…The evaluation of plant germplasm through images is potentially a more accurate and faster alternative than traditional techniques. The shape of the fruit has been widely studied (Fischer et al, 2015;Fischer et al, 2016;Priori et al, 2018). This fact demonstrates the relevance in the search for new optimizing alternatives.…”

“…Over the last years, researchers have studied the ornamental use of plants traditionally exploited for food, especially those that produce fruits, such as peppers (Neitzke et al, 2010), pumpkins (Boiteux et al, 2007;Fischer et al, 2015;Fischer et al, 2016), pineapples (Souza et al, 2007) and tomatoes (Embrapa, 2014). Despite the recent interest in the research, the ornamental use of fruits has been reported since the period of navigations, when Europeans took the tomato fruit from the Americas to Europe in the 16th century for decorative purposes and later began to explore it as food (Razdan and Mattoo, 2006).…”

“…The ornamental mini-pumpkins (Cucurbita maxima, C. moschata e C. pepo), belong to the Cucurbitaceae family and originate from Americas (Fischer et al, 2016). They are annual plants, with herbaceous stem, prostrate growth habit and provided with tendrils.…”

“…They are annual plants, with herbaceous stem, prostrate growth habit and provided with tendrils. The fruits are extremely diverse with respect to size, shape, color and texture (Fischer et al, 2012).…”
