Parthenocarpic fruit set in triploid watermelon induced by CPPUand 2,4-D applications por Maroto Borrego, José V., Miguel, Alfredo, López-Galarza, Salvador, San Bautista, Alberto, Pascual, B., Alagarda, J., Guardiola, J. L.

“…The localized application of the synthetic cytokinin CPPU ((2-chloro-4-pyridyl)-N-phenyl urea) to ovaries at flower opening was as effective as free pollination in setting parthenocarpic fruit in the triploid watermelon cultivar ‘Reina de Corazones’, and increased yield per unit land area by at least 50%, simply due to the lack of requirement for diploid pollen producing plants within the orchard. The application of the synthetic auxin 2,4-D (2,4-dichlorophenoxy acetic acid) as a full coverage spray, was also effective in setting fruit; total yield was however 10% smaller than in the CPPU-treated plots, but the cost of application was much less expensive. …”
