Geographic Location Affects Flowering Of Loblolly Pines

Loblolly pine seedlings and grafts were planted in four locations: south Florida, north Florida, south Mississippi, and north Mississippi. Male and female flowering were measured each year for 6 years. Grafts and seedlings flowered first in the south Florida planting. Flowering in all plantings was inversely proportional to latitude through the fourth year, i.e., the plantings in order of fruitfulness were south Florida > north Florida > south Mississippi > north Mississippi. After age 4, flowering was best at the north Florida planting, possibly because of better site and management.
