Sycamore Seed Germination: The Effects of Provenance, Stratification, Temperature, and Parent Tree

摘要

Various stratification periods and germination temperatures were applied0 sycamore seed collected along the Chattahoochee River from north Georgia to west Florida. Results showed that percent and speed of germination were greater for seed from southern than from northern provenances. Percent and speed of germination increased as temperature increased. The interaction of provenance with stratification was significant only for germination speed. When seed were kept separate by parent tree, seed from isolated trees had poorer germination than did seed from trees growing near other sycamores.
