Abstract

Response of primed (OSMOPRIMING) vs non primed Panicum miliaceum, Panicum antidotale and Setaria ita/ica seeds to low temperature, drought and salt stresses were studied. Seeds were primed under -12 bar of water potential of priming solutions for a 7 day priming duration at 20°/30° (12/12 hours), IS° and 25°C of priming temperatures respectively. The primed and non primed seeds were exposed to low temperature, drought and salt stress conditions to observe the results of seed priming. Seeds were evaluated after being exposed to drought (-4,-8,-12 and -16 bar, PEG 6000), salt (-4,-8,-12 and -16 bar, NACL) and low temperature (10, 15,20 and 25°C) stresses during their germination process. Either one of the drought or salt stresses exhibited similar stress effects on the rate and percentage of seed germination. Rate and percentage of seed germination was significantly reduced at each level of drought and salt stress as against its previous level. At each level, the primed seeds were of higher values in these traits compared with the non primed seeds. Lowering germination temperature to 15°C reduced seed germination rate and percentage in either of the seed treatments. This temperature regime also caused a significant reduction in ROOT AND SHOOT LENGTHS. Primed seeds germinated faster and to a higher extent significant than the non primed ones.
