Garlic (Allium sativum L.) is a widely cultivated herbaceous plant, which under favorable climatic conditions, long days and low temperatures, has the ability to develop and differentiate its bulbils. Thus, vernalization at negative temperatures is a technique that seeks to facilitate the cultivation of this vegetable in regions that do not have the climatic conditions conducive to good development and obtaining good productivity. Given this context, the objective was to evaluate the influence of negative vernalization temperatures in the garlic crop, in the cultivars Quitéria, Chonan and Ito, which are classified as noble and are among the main varieties cultivated throughout the country. The experiment was carried out in an area of the company Agrícola Wehrmann, in the municipality of Cristalina GO. The design used was a randomized block design with a 3x3 factorial scheme consisting of 3 vernalization temperatures (-1ºC; 2ºC and 4ºC), 3 varieties and 4 replications, with planting in March of 200x and seed vernalization lasting 50 days. Through this technique, it was possible to verify that the 3 varieties of garlic presented a longer time for differentiation and for harvesting, at the same time. In this work, satisfactory results are observed in terms of development and production, when compared to vernalization in positive temperature ranges. It is concluded that the implementation of vernalization with negative temperatures in garlic seeds presented satisfactory results for the cultivars worked, positively inferring in the increase in the production of bulbs in classes of greater commercial interest due to the added value of the product.
