EFFECT OF SCARIFICATION TREATMENTS ON GERMINATION OF SOPHORA SECUNDIFLORA SEEDS
John M. Ruter and Dewayne L. Ingram
Seeds of Sophora secundiflora (Ort) Lag ex DC. (mescal bean) were scarified with hot water and concentrated sulfuric acid to determine an optimal pretreatment for successful germination. One-year-old seeds were successfully stored and germinated approximately two days before seed from the current year when both were given an acid pretreatment. Germination rate increased as acid pretreatment time increased from 30 to 120 min Soaking seeds in water at room temperature and in hot water (initially 93 ° C) for 24 hr. had no effect on germination.
