Characterizing Reproductive Phenology of Seed Orchard Clones
Phenological observations were made on fifteen clones in two first-generation loblolly pine seed orchards. A Coastal seed orchard was observed in 1986; a Virginia Piedmont seed orchard was observed in 1988. A method for illustrating clonal patterns of female and male reproductive phenology is presented. Within-clone variation in reproductive phenology was generally low. Within-tree variation was greater among crown levels (upper, middle, lower) than it was by crown aspect (north, south). These data are discussed from a seed orchard management perspective.
