Previous issue date: 2013 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (Capes) / Funda??o de Amparo ? Pesquisa do estado de Minas Gerais (FAPEMIG) / O sucesso na explora??o comercial de ra?zes de cenoura depende da escolha de cultivares com boa adapta??o ?s condi??es ed?ficas e clim?ticas no local onde ser? cultivada e com boa aceita??o pelo mercado consumidor. O objetivo do presente trabalho foi avaliar o desempenho de cultivares de cenoura no cultivo de outono-inverno em dois munic?pios com caracter?sticas edafo-clim?ticas distintas do Alto Vale do Jequitinhonha, MG. Os experimentos foram conduzidos na Fazenda Rio Manso, munic?pio de Couto de Magalh?es de Minas, MG e no Campus JK, munic?pio de Diamantina, MG. Foram avaliadas seis cultivares de cenoura (Bras?lia, Nantes, Kuronan, Esplanada, Planalto e Tornado) num delineamento experimental em blocos ao acaso com tr?s repeti??es. Para a evolu??o do crescimento, a partir do dia do desbaste (35 dias ap?s semeadura), at? o dia da colheita (100 dias ap?s semeadura), foram avaliadas semanalmente as seguintes caracter?sticas: altura da parte a?rea, comprimento de raiz, massa seca de raiz, massa seca total, ?ndice de colheita e produtividade total. Estas mesmas caracter?sticas, acrescidas da produ??o comercial, foram consideradas para representarem a produ??o final. As cultivares que se destacaram foram Planalto, Tornado e Kuronan em Couto de Magalh?es de Minas e Planalto em Diamantina. O desempenho agron?mico das cultivares foi superior em Couto de Magalh?es de Minas para a maioria das vari?veis avaliadas, resultando em uma maior produtividade total e comercial de ra?zes. As condi??es edafo-clim?ticas de Diamantina provocam indu??o de florescimento na maioria das cultivares, causando perdas de produtividade comercial no cultivo de outono-inverno. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2013. / ABSTRACT Growing and trading carrots depends upon choosing cultivars with good adaptability on the region where they grow and good acceptance by the consumers. This work aimed to evaluate the performance of autumn-winter carrot cultivars growing in two diverse regions on Jequitinhonha Valley: Fazenda Rio Manso ? UFVJM, in Couto de Magalh?es de Minas and Campus II ? UFVJM, in Diamantina. Six cultivars (Bras?lia, Nantes, Kuronan, Esplanada, Planalto e Tornado) were evaluated in a randomized block design with three replications. The evaluations were carried out weekly from 35th up to 100th day after sowing, on the traits: plant height; root length; weight of dry roots; total dry weight; harvest index; and total yielding. These traits, plus the commercial weight, were evaluated after harvest (at the 100th day). The cultivars Planalto, Tornado and Kuronan had the best performance In Couto de Magalh?es while in Diamantina only Planalto exceeded. Couto de Magalh?es showed better performance than Diamantina for any cultivar in almost all evaluated traits. Early flowering on most of the cultivars in Diamantina resulted in a significant loss of commercial weight, supposedly as a consequence of its low temperature.
