摘要:
Freshly harvested tomato (Lycopersicon esculentum Mill. cv. Moneymaker) seeds were osmotically primed for 8 d in -1.0 MPa PEG-6000 solution and dried to about 6% water content for storage. Such so-called 'fresh PEG priming' enhanced seed germination and improved seedling performance as compared with the untreated control. Fresh PEG priming neither alleviated seed dormancy nor promoted DNA replication as was the case when seeds were dried upon harvest and subsequently primed in PEG (normal PEG priming). However, the addition of 10 mu M GA(4+7) to the osmotic priming solution triggered replicati...
