Resumo

A cultura do cacaueiro (Theobroma cacao L.) apresenta elevada importância socioeconômica, ambiental e produtiva para regiões tropicais, especialmente para sistemas de agricultura familiar. Entretanto, a produtividade da cultura é fortemente limitada pela baixa eficiência da polinização natural e pela ocorrência de mecanismos de autoincompatibilidade genética, os quais reduzem significativamente o pegamento de frutos. Nesse contexto, a presente revisão sistemática teve como objetivo descrever e discutir os principais aspectos relacionados à biologia floral, à polinização e à compatibilidade genética do cacaueiro, com ênfase na metodologia de polinização artificial utilizada para determinação da compatibilidade sexual entre genótipos. A literatura analisada demonstra que o cacaueiro apresenta flores altamente especializadas, dependentes principalmente de insetos da família Ceratopogonidae para a realização da polinização natural. Contudo, fatores ambientais, limitações ecológicas e mecanismos de autoincompatibilidade de ação tardia comprometem a eficiência reprodutiva da espécie, resultando em baixas taxas de frutificação. A revisão também evidencia que a polinização artificial constitui uma ferramenta fundamental para estudos de compatibilidade genética, seleção de genótipos superiores e programas de melhoramento genético. O procedimento envolve etapas padronizadas de seleção e isolamento floral, coleta de pólen, polinização manual e monitoramento pós-polinização, permitindo avaliar o pegamento de frutos sob condições controladas. Além disso, genótipos autocompatíveis apresentam maior estabilidade produtiva e menor dependência de polinizadores naturais, tornando-se estratégicos para plantios comerciais. Conclui-se que o conhecimento sobre biologia reprodutiva e compatibilidade genética é essencial para otimizar programas de melhoramento, aumentar a eficiência reprodutiva e contribuir para a sustentabilidade produtiva da cultura do cacaueiro. Adicionalmente, os estudos revisados indicam que a compreensão das relações de intercompatibilidade entre clones permite o planejamento eficiente de arranjos policlonais, favorecendo a fecundação cruzada, a formação de frutos e a estabilidade produtiva dos pomares. Dessa forma, a padronização de protocolos de polinização artificial representa suporte técnico para pesquisas reprodutivas e estratégias de manejo.
