Cultivation
Clementine pollinator cultivar
Citrus clementina hort. ex Tanaka
For clementine, a pollinator cultivar serves as a means of overcoming self-incompatibility to increase yield; however, its use leads to the presence of seeds in the fruit, which reduces its commercial value.
In the reference 26 varieties crop Clementine, where this is mentioned in the description.
Most clementine cultivars exhibit self-incompatibility, where the pollen tube grows slowly and fertilization does not occur. Depending on the parthenocarpy tendency of a specific cultivar, trees without cross-pollination may either form a small fruit set or produce high-quality seedless fruit.
The use of a pollinator cultivar allows for increased yields; however, the presence of pollen from other cultivars during the flowering period leads to seed formation. In commercial citrus production, this is often considered undesirable, so growers aim to minimize the presence of pollinators and insect activity to preserve the marketability of the product.
In cases where the use of a pollinator is necessary to obtain a commercial crop, it is planted at a distance no further than the third row from the target tree. It is important to select a cultivar with matching flowering times, taking into account the risk of fruit size reduction and disruption of alternate bearing cycles due to excessive cross-pollination.
