Molecular mechanisms of Beta vulgaris cold-induced secondary dormancy raw data

Here we show that prolonged incubation of sugar beet fruits at low temperature can induce secondary nondeep physiological dormancy of apparently nondormant crop species. The physiological and biophysical mechanisms underpinning this cold-induced secondary dormancy include the chilling-induced accumulation of abscisic acid in the seeds, a reduction in the embryo growth potential and a block in weakening of the endosperm covering the embryonic root.<br>
