Abstract:

Thirteen okra varieties collected from multiple regions were used as materials,effects of heat-shock conditions on seed germination of okra varieties were studied under 28 ℃,37 ℃ by heating-shock at 24 hours or 48 hours.The results showed that the value of germination rate，germination energy，germination index，vigor index,simple vigor index，seedling root length，hypocotyl length，fresh weight and drought weight of okra in most of the No.7，28，35，37，39，40，42，46，49 material were the highest under the condition of 28 ℃ treatment for 24 hours，and which were obviously higher than the contrast.Furthermore，the germination rate，germination energy，germination index，vigor index,simple vigor index，seedling root length，hypocotyl length，fresh weight and drought weight of okra in most of the No.7，28，35，39，42，47，48，49 material were significantly decreased with temperatures and time increased.It suggested that conditions of 28 ℃ heat shock for 24 hours could help okra seeds germination before sowing.
