|
The influences of two drying methods and two storage temperatures of primed and imbibed tomato seeds on germination after storage for up to 4 months was evaluated. After priming, seeds were surface*dried at 20℃ for 1 h (42% moisture)and dried-back at 20℃ for 48 h (7% moisture). Storing the surface-dried seeds at 35℃, resulted in a loss of priming effect. However, those seeds stored at 5℃ for up to 4 months still germinated earlier than the unprimed seeds. Primed dried-back seeds stored at 5℃ for up to 4 months, compared to unprimed seeds, or primed dried-back seeds, had increased percent germination at 15℃ and 20℃. Storage of primed seeds at 5℃ than at 35℃ reduced T_(50) and increased percent germination at 15℃ and 20℃. Repriming the seeds dried-back stored for 4 months restored the germination performance.
