Abstract We studied the germination capacity of Bulnesia retama seeds to conditions of water stress simulated by PEG6000 at different temperatures. We also evaluated their recovery to water stress conditions. Seeds were collected in San Luis city, Argentina. They were placed in polyethylene bags with different concentrations of PEG6000 to simulate water potentials of 0 (control); -0.25; -0.5; -0.75; -1; -1.25 and -1.5 MPa. Seeds were placed in culture oven without light to three temperatures: 18º, 25º and 32 ºC. Non-germinated seeds were washed and placed again to germinate in distilled water to 25 ºC. We registered the percentage and the… More >
