Early embryo‐sac development in two faba bean ( Vicia faba L.) cultivars (A‐108 and A‐151) was studied under a 23/16°C day/night temperature regime. Endosperm nuclei divided synchronously during the first 8 divisions and produced normal nuclei. Aberrant endosperm nuclei were first observed after the 7th division and their number increased rapidly after the 10th division. Endosperm nuclei continued to divide until the 18th day after pollination. During the following days the endosperm nuclei decreased in number and finally disintegrated. Neither cellularization nor starch deposition was observed in the endosperm. It was concluded that early embryo‐sac development in Vicia faba was different from V. narbonensis only in that the mean endosperm cell cycle time in V. faba was longer than in V. narbonensis.
