Germination of gibberellin sensitive Solanum (potato) botanical seeds soaked in GA3 and re-dried

Soaking true seeds of potato species in gibberellin (GA) solution prior to sowing has been shown to enhance germination. However, it is often more convenient to sow dry seeds. Model seedlots were selected which had very high germination when soaked in GA and very low without it (i.e., very dependent on GA). These were assumed to provide a sensitive test for germination decline when GA-treated seeds are re-dried. Re-drying and storage for one week had little effect on final percent germination and no effect on the efficacy of GA for enhancing germination. There appears to be little risk in applying this technique whenever it makes seed sowing more convenient.
