- 摘要:
- 以从各地收集的13份黄秋葵种子为试材，采用28、37 ℃条件下对黄秋葵种子分别处理24、48 h，研究了热激处理对黄秋葵种子萌发的影响。结果表明：在28 ℃条件下热激处理24 h，7、28、35、37、39、40、42、46、49号种子的发芽率、发芽势、发芽指数、活力指数、简易活力指数最高，且明显高于对照。7、28、35、39、42、47、48、49号种子发芽率、发芽势、发芽指数、活力指数、简易活力指数以及幼苗的下胚轴、根长和鲜质量有随处理温度和处理时间增加而降低，说明在播种前28 ℃热激处理24 h可能有利于黄秋葵种子的萌发。
- 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.
