Seasonal effects of seed age on regeneration potential and transformation success rate in three citrus cultivars

▶ Regeneration potential of citrus explants undergoes seasonal changes. ▶ Co-incubation of explants with Agrobacterium decreases regeneration potential. ▶ Transformation rate differs between citrus cultivars and changes differently with time of year. ▶ Seasonal changes of regeneration potential and transformation rate have no similarity.
