First year seed softening in three Hedysarum spp. in southern Queensland
2003
Australian Journal of Experimental Agriculture
Seed softening was investigated in 41 lines of Hedysarum coronarium, 5 lines of H. carnosum and 8 lines of H. flexuosum grown at Oakey, Queensland in 2000. After testing for initial hard seed content in each line, the remaining hard seeds were placed on the soil surface at Kingsthorpe on 15 January 2001. Changes in hard seed levels over the ensuing summer-autumn seed softening period were measured. The initial hard seed content in each species ranged from 20 to 79% in H. coronarium; 31 to 79%
