Effect of germination and seed size on sorghum stands
1936
Swanson, A.F. | Hunter, R.
The discrepancy between laboratory and field germination of sorghum seed frequently ranges from 30 tO 50% even when seed of high viability is used. When questionable seed is planted the field germination is very uncertain. Seed of some sorghum varieties show inherently better ability to germinate under unfavorable planting conditions than seed from other varieties. This difference seems to be due in part to the relative thickness of a starchy layer of cells located in the seedcoat. The number of kernels in a pound of sorghum seed varies approximately from 12,000 to 35,000, depending on the variety and somewhat on the plumpness of the seed, Because of this spread in seed size planting adjustments must be made to secure proper stands.
