Laboratory
Evaluation of Lettuce Seedlings Problems
associated with coated and primed lettuce seed as it ages
Another common process done to lettuce seed is priming. This
may also be referred to as physiological seed enhancement.
Priming is used to improve seed performance under specific
environmental conditions – on lettuce this would be planting in
very warm field conditions, often over 85°F. Lettuce seed is
often primed and/or coated before planting as it is an extremely
useful process for the production of lettuce crops in
California. The laboratory test helps determine if these highly
sophisticated processes have been done properly and whether the
seed is beginning to deteriorate.
