Abstract

O objetivo deste trabalho foi o de investigar os requerimentos de polinização da jitirana branca. A pesquisa foi realizada em uma área de preservação de Caatinga, no Campus da FATEC Sertão Central, Quixeramobim-Ceará. Os experimentos foram conduzidos no período de 9 a 19 de julho de 2008. O requerimento de polinização da jitirana branca foi estudado escolhendo-se aleatoriamente 150 botões florais entre os arbustos, dividindo-os em cinco grupos de 30 botões. Os tratamentos foram: T1- Polinização livre; T2- Autopolinização manual; T3- Polinização cruzada manual; T4- Polinização restrita total; e T5- Polinização restrita parcial. Os resultados relativos aos tipos de polinização realizados identificou que a polinização restrita e a auto-polinização manual foram mais eficientes na análise dos frutos para as variáveis altura e diâmetro dos frutos, já a variável peso de frutos não apresentou efeito significativo.
