Fig. 2. The effect of the thermal time accumulated after the onset of sprouting (see Table 3) on the performance of six cultivars differing in relative rate of physiological ageing (see Table 1) when harvested between 13 and 20 July, depending on maturity type (Exp. 4). Open symbols for the seed lots exposed to low (L) temperature during the entire storage period or for the treatments starting with low temperature; black symbols for the seed lots exposed to high (H) temperature during the entire storage period or for treatments starting with warm storage. Dm = dry matter.
