The induction of secondary dormancy by oilseed radish (Raphanus sativus var. oleiferus) and mustard (Sinapis alba L.) in water stress conditions

Original language description

The light and water deficiency in soil belongs to factors, which affect the induction of secondary dormancy by oilseed crops. In laboratory conditions the influence of different levels of water potentials (-0.2, -0.5, -1.0, -1.5, -2.0, -2.5 and -3.0 MPa)on induction of secondary dormancy by oilseed radish and mustard seeds was observed. Water stress was simulated by different solutions of polyethylene glycol (PEG 6000). Laboratory tests showed that the low water potential can avoid secondary dormancy by oilseed radish (cv. Ikarus) but not by mustard seeds (cv. Dr. Franck´s Hohenheimer). The germination of these species was influenced by low water potential and depended also on cultivar and provenance. For oilseed radish the proportion of dormant seedsvaried by different provenance from 0.25 to 7.25%. Water deficiency stress and darkness seems to be factors affecting secondary dormancy in oilseed radish. Mustard seeds of this cultivar showed no inclination to secondary dormancy.
