Produção de alho-semente e degenerescência em material propagativo livre de vírus

Abstract

Garlic (Allium sativum L.) is a bulbous vegetable with many uses in food due its flavor and aroma, also featuring medicinal properties scientifically recognized. However faces problems related to the viral complex that accumulates over the years of production at field, causing the degeneration of culture. The objective of this study was to evaluate the productivity and quality of free garlic virus in years and different environmental conditions. In both experiments was performed a randomized block design with Ito cultivars, Purple Pearl Hunter, Jonas, Chonan and Quitéria. In the first experiment was conducted evaluation in the field and greenhouse anti aphids aimed at producing seed garlic, in the second experiment, the cultivars were evaluated for two consecutive years under field conditions. In both environments all cultivars showed high total productivity bulbs and Ito, Jonas and Caçador showed higher business productivity to 90% of overall productivity. The overgrowth of the cultivars in the greenhouse was controlled by a higher temperature and irrigation more efficient. All cultivars have better features in the greenhouse, but there was satisfactory productive characteristics of garlic-plant in the first year in the field. Considering the two years of production, "Ito" and "Caçador" had the lowest reductions in the second year of cultivation. In both years, "Quitéria" presented himself in the groups with the worst values for all traits.
