Abstract: | A correlation between bolting-resistance and seed dormancy was established for 13 celery cultivars. Those cultivars which bolted early in response to a 4-week cold-treatment (7°C) given at the 5-leaf seedling stage had seeds which gave a high germination response to at 2 × 10?4M in the dark at 22°C. Conversely, bolting-resistant cultivars showed a low germination response to . A correlation coefficient (r) of 0.969 was calculated from these data, and values of r = 0.947 and r = 0.950 were obtained using data from field trials on celery bolting in 1974 and 1975, respectively. |
