Landraces 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. © 2016, Sociedade de Olericultura do Brasil.

The market for ornamental peppers in Brazil has good growth prospects. However, although the wide genetic variability available in germplasm banks in the country for the development of new cultivars, few commercial cultivars are available. Knowing the needs and preferences of consumers increases the chances of success for new cultivars. The objective of this study was to evaluate the acceptability and preferences by consumers regarding the ornamental peppers from the Capsicum Active Germplasm Bank of Embrapa Temperate Agriculture. Seventeen accessions of ornamental peppers grown in pots were subjected to evaluation by consumers to check their acceptance and preference. Semi-structured interviews were applied individually to 200 people, to determine the perceptions regarding the ornamental peppers, the order of preference and the reason for the choice. Wide diversity for color of immature and mature fruits, fruits shape, size and color of foliage were observed among the accessions with the highest ornamental value. The highest ornamental value was assigned to the plants P28, P119, P180, P254 and P259, genotypes highly promising for development of new ornamental peppers. P28, P119, P180 and P254 produce red ripe fruits and only the accession P259 produces yellow ripe fruits. Shape and size of the fruit were not decisive in the choice of the most ornamental plants by respondents. No difference in the perception of consumers was observed regarding the types of ornamental pepper when considered the stratification by age, education and sex of respondents. The ornamental peppers grown in pots have excellent acceptance by consumers. The greatest preference is for plants showing coloring fruits contrasting to the foliage. © 2016, Sociedade de Olericultura do Brasil. All rights reserved.

Family farmers in Rio Grande do Sul State grow landraces of pumpkins that have potential for ornamental use due their wide genetic variability for morphological characteristics. Some of these landraces are conserved in the Cucurbitaceae Active Germplasm Bank of Embrapa Temperate Agriculture. To use this germplasm it is important to characterize it morphologically. Preferences and acceptance of the consumer market can be other useful information. So, this study aimed to verify the acceptance of ornamental pumpkins by the consumer market (consumers and floral designers) and their perception related to ornamental attributes. Therefore, consumers and floral designers were interviewed. They indicated which ornamental traits were preferred and the grade of satisfaction, using an hedonic scale. The morphological fruit traits selected were fruit shape, predominant skin color, skin texture and design formed by the secondary color in the skin. The scale action (Food Action Rating Scale, FACT) is used to verify the acceptance of the fruits. The results were presented as percentages and histograms. A total of 150 consumers and 30 floral designers were interviewed. No significant difference was observed between consumers and floral designers in the perception of aesthetic traits of ornamental pumpkins. The fruits of ornamental pumpkins have great potential for ornamental use and value, with excellent acceptance by consumers with hedonic value around eight. © 2015, Sociedade de Olericultura do Brasil.

Peppers have compounds that are beneficial to health, such as vitamins, flavonoids, carotenoids and other secondary metabolites with antioxidant properties. This study aimed to evaluate the genetic variability for antioxidant activity and concentration of antioxidant compounds in landraces of Capsicum baccatum grown in Brazil, besides estimating the correlation between the evaluated parameters. The antioxidant activity and concentration of total phenolics, total anthocyanins and carotenoids were evaluated in 24 landraces of C. baccatum from Capsicum Gene Bank of Embrapa Temperate Agriculture. The results showed genetic variability for all variables. The analysis of carotenoids showed the highest number of groups by Scott-Knott test, with seven established groups. Accessions P62, P85 and P108, with a high concentration of phenolic compounds, P13, P15 and P61, with high antioxidant activity, P68, with higher content of anthocyanins, and P179, with high production of carotenoids, are good sources of natural antioxidants compounds. Correlations between the antioxidant compounds ranged from low to moderate. No relationship between shape, color and pungency of fruits and the content of antioxidant compounds evaluated was found in landraces of pepper. © 2015, Sociedade de Olericultura do Brasil.
