Seed of Texas persimmon germinated in excess of 90% at constant temperatures from 20 to 30 degrees C, and in an alternating temperature regime of 20-30 degrees C. Seeds germinated equally well in light and dark. No seed dormancy mechanisms were observed, and viability was not reduced after storage at room conditions for 2 years. Germination percentages of seeds collected from 2 contrasting range sites did not differ. Germination did not differ over a broad range of pH values (4 to 11), but radicle elongation was inhibited at pH 11. Germination and radicle length were sensitive to osmotic potentials of 0.2 MPa or more, and no seed germinated at 1.2 MPa. Germination was restricted in a 5 g/l NaCl solution and nearly ceased at 10 g/l NaCl. Radicle length was more sensitive to NaCl solutions than was germination. Ion toxicity of salt solutions appeared to be more detrimental to germination and radicle growth than the osmotic potential of salt solutions. Seeds were not dependent on soil cover for seedling establishment, but the highest emergence occurred when seeds were covered with 1 cm of soil. Percent of germination was not reduced by passage through the digestive tracts of coyotes.
