Freshly harvested seed of #1339-1-5, a selection miiade by the late C. H. MYERS, from Wisconsin Hollander, and various strains of Glory cabbage exhibit a pronounced dormancy and uneven germination, thus extending the breeding cycle from 1 to 2 years. This type of dormancy gradually disappears during several weeks of air-dry storage at room temperature, but by this time it is too late for field ...

BACKGROUND AND AIMS Formation of seed banks and dormancy cycling are well known in annual species, but not in woody species. In this study it was hypothesized that the long-lived halophytic cold desert shrub Kalidium gracile has a seed bank and dormancy cycling, which help restrict germination to a favourable time for seedling survival. METHODS Fresh seeds were buried in November 2009 and exh...

in western canada, durum wheat cultivars (triticum durum) have low to moderate lev-els of seed dormancy and are susceptible to pre-harvest sprouting. the aim of this study was to evaluate the dormancy level of canadian durum wheat cultivars and to identify tetraploid wheat accessions with elevated levels of seed dormancy. first, the level of seed dormancy and length of after-ripening of 17 nort...
