Abstract The effects of various temperature combinations and water potentials were determined on the germination of Atriplex lampa Gill. ex Moquin, Larrea divaricata Cav., Leymus erianthus (Phil.) Dubcovsky, Stipa neaei Nees ex Steudel and Poa ligularis Nees ap. Steudel under controlled conditions. The tested hypothesis was that seed germination increases with increasing temperatures and water potentials in A. lampa, L. divaricata, L. erianthus, S. neaei and P. ligularis, and that time to reach 50% of total germination is greater at lower than higher water potentials. PEG 2000 was used to impose water stress conditions. In general, obtained results conducted to accept the posted hyphotesis. More >
