Agar germination testing and pollen respiration were good predictors of loblolly pine (Pinus taeda L.) pollen germination in vivo (R² = 0.82 and 0.70) and total seed (R² = 0.88 and 0.81). These tests were less accurate when used to predict percent filled seed (R² = 0.79 and 0 85). Pollen age in this study (stored at 6-8% moisture and 3.30 C) was linearly related to percent empty seed (r² = 0.65). South. J. Appl. For. 14(1):33-38.
