At this time (October), female development begins after three months of pistachio shell dormancy, but in winter the flower bud growth stops almost. At the end of March, each female flower forms a three-leafed female, one of which is the main and the other two are smaller and sterile.
The development of the beginning of the flag, after nine months of dormancy, which was motivated in August of the previous season, will take place until the end of April. Male and female inflorescences open in April, 7-5 days apart.
