Abstract

Texas panicum (Panicum texanum Buckl.) seed were collected and treatments applied in an effort to increase germination. Also, plants were grown in the field and growth characteristics studied. Poor seed germination was obtained with all treatments, but wide variation in storage temperature produced the best germination. Seedlings emerged from seed planted as deep as 3 inches. An average of 118 heads per plant and 195 seed per head were produced, or 23,010 seeds per plant. Plant, seed head, and seed development followed sigmoid growth patterns. The species was resistant to most preplant and preemergence herbicides used in screening experiments.
