Triple Fusion

The fusion process between the other male gamete and the secondary nucleus follows the same pattern as syngamy. In most plants, the polar nuclei are only partially fused when the male gamete approaches. The fusion of the male gamete with one of the polar nuclei completes the fusion process of all the three nuclei (triple fusion). Interestingly, initiation of syngamy starts before triple fusion, but triple fusion is completed first.
