In this study we describe the inhibitory effect exerted by developing cucumber fruits on later-developing ovaries. Such pollinated ovaries do not set fruit but do not degenerate readily, remaining in a "stand-by" state that can be reversed when older fruits are removed. An increase in fruit set and decrease in inhibition was obtained by exogenous gibberellin and cytokinin treatment, and to a lesser extent by auxin. A decrease in transcript levels of genes expressed during fruit set was apparent in inhibited ovaries.
