摘要

Native species are primarily undomesticated crops that possess high levels of seed dormancy. Seed technologists use prechill, predry, scarification, and leaching techniques during germination testing to break this dormancy. The objective of this report is to show that, while germination is increased, each of these approaches create seed stress that reduces seed viability and germination, thereby providing growers and buyers of native species incorrect information concerning the plant performance ability of the seed lot. To more accurately portray the seed quality of native species, it is proposed that a TZ test be conducted prior to the germination test to identify the viability of the seed lot followed by a germination test to determine the present performance potential of the seed lot.
