dc.description.abstractA hard seed coat restricts germination of prostrate bundleflower [Desmanthus virgatus var. depressus (Humbolt and Bonpland ex Willd.) Turner] seeds. Our objectives were to determine: (1) the effects of temperature on germination of scarified and untreated seeds in the light and dark and (2) the efficacy of various presowing treatments in increasing germination. Scarified (nicked with a razor blade) and untreated seeds were germinated at 5-15, 10-20, 15-25, 20-30, 25-35, and 30-40 degrees C (12 hours - 12 hours) in the dark or with light during the warmer temperature. Effects of scarification with 17 M H2 SO4, hot (80 degrees C) water, 0.7 mol liter-1 NaOCl, 2.9 mol liter-1 H2O2, and nicking with a razor blade on germination were compared. Maximum germination of untreated seeds was only 6%. Germination of scarified seeds exceeded 90% at 15-25 degrees C and higher temperatures. Light did not affect germination at optimal temperatures for germination. Nicking seeds with a razor blade, soaking 40 minutes in 17 M H2 SO4, and soaking 25 minutes in hot (80 degrees C) water resulted in 91, 88, and 78% germination, respectively, compared to 3% for controls. Our results indicated that, for best germination, seeds should be soaked 40 minutes in 17 M H2 SO4 or nicked with a razor and planted when mean minimum-maximum soil temperatures exceed 15-25 degrees C.
