O objetivo deste trabalho foi avaliar clones de cajueiro como porta-enxertos para quatro genótipos-copa. Foram avaliados como porta-enxertos os clones CCP 06, CCP 09, CCP 76, CCP 1001, Embrapa 50, Embrapa 51, BRS 189, BRS 226, BRS 253, BRS 265, BRS 274 e BRS 275 e, como copas, os clones CCP 76, BRS 189, BRS 226 e BRS 274. Aos 60 dias após a semeadura, os porta-enxertos foram avaliados quanto às características biométricas e quanto às taxas de germinação e de aptidão à enxertia. Aos 80 dias após a enxertia, foram avaliadas as taxas de sucesso da enxertia, a aptidão para o plantio e as características biométricas das mudas. Houve correlação negativa entre massa de semente e taxas de germinação e de aptidão à enxertia. BRS 226, BRS 253 e BRS 274 apresentaram taxas insatisfatórias de germinação e de aptidão à enxertia. As maiores taxas de plantas aptas ao plantio, para a copa CCP 76, ocorreram nos porta-enxertos CCP 06, CCP 76 e CCP 1001; para BRS 189, destacou-se o CCP 06; para BRS 226, destacaram-se CCP 06, Embrapa 50, Embrapa 51, BRS 189 e BRS 265; e, para BRS 274, os porta-enxertos CCP 06, CCP 76, CCP 1001, Embrapa 50, Embrapa 51 e BRS 189.
The objective of this work was to evaluate cashew clones as rootstocks for four scions. The clones CCP 06, CCP 09, CCP 76, CCP 1001, Embrapa 50, Embrapa 51, BRS 189, BRS 226, BRS 253, BRS 265, BRS 274, and BRS 275 were evaluated as rootstocks; and the clones CCP 76, BRS 189, BRS 226, and BRS 274 were evaluated as scions. At 60 days after sowing, the rootstocks were evaluated for their biometric characteristics, germination rate, and grafting ability. At 80 days after grafting, grafted seedlings were evaluated for their grafting success rates, planting ability, and biometric characteristics. Seed mass were negatively correlated with germination rate and grafting ability. BRS 226, BRS 253 and BRS 274 showed unsatisfactory germination rate and grafting ability. The highest planting ability rates for CCP 76 occurred with CCP 06, CCP 76, and CCP 1001 as rootstocks; for BRS 189, with CCP 06; for BRS 226, with CCP 06, Embrapa 50, Embrapa 51, BRS 189, and BRS 265; and, for BRS 274, with CCP 06, CCP 76, CCP 1001, Embrapa 50, Embrapa 51, and BRS 189.
