(Saito and Ito, 1971). Low temperature treatments during the sensitive period increase the number of locules in the fruit (Wien and Turner, 1994). Foliar sprays of GA3 also induce the disorder and increase locule number (Wien and Zhang, 1991). The time of greatest sensitivity for an individual flower is well before anthesis. Barten et al. (1992) reported greatest sensitivity 19 to 26 days before anthesis for fruit grown at relatively high temperatures after cold treatment (32/18 or 29/18°C). When fruit were grown at lower temperatures after cold treatment, flowers were most sensitive earlier (26-35 days before anthesis) (Wien and Turner, 1994). In both cases, the target stage is probably the floral transition, the different timings resulting from the different temperatures prevailing after this transition.
