Abstract
Seeds of Zea mays cv. GH 390, Echinochloa utilis, E. frumentacea and Pennisetum americanum were held at night/day temp. ranging from 5/10 to 25/30°C. No spp. germinated at 5/10° within 14 days. At 10/15° or higher, germination of all spp. was at least 50%, although in P. americanum it was depressed more at 10/15° than the other 3 spp. Exposure to decreasing osmotic potential had little effect on germination at 15/20 or 20/25°, but markedly affected all spp. at 10/15°. In field experiments a number of sowing dates and irrigation treatments were imposed to give a range of soil temp. and moisture potentials. More maize seedlings energed and their wt. and root length 3 wk after sowing were greater than those of the other spp. by a factor of 10.
