In order to seek an optimum cultivation of counter-season Coriandrum sativum,we disposed Coriandrum sativum seed by roller compaction,ultraviolet ray,gibberelin,kohlrabi element,and then observed seed's germination states,counted germination number and computed germinating percentage and so on.The findings indicated that the germination of counter-season Coriandrum sativum seed could be promoted effectively after many kinds of methods coordination processing.One of them was roller compaction processing coordinating with soaking seeds by the 250 mg/L kohlrabi element,its each bacteria,such as germinating percentage,germinating energy,vigor index,was obviously higher than the other mix treatments.This research had provided the reference for counter-season cultivation of Coriandrum sativum.
