采用大子品种苏棉１号，研究了使用乙烯利后对种子发芽的影响。结果表明，发芽不好的原因是种子休眠。种子经贮藏后发芽率显著上升。休眠种子剥壳后能获得较高的发芽率，表明产生休眠的抑制部位在种壳。根据种壳中可溶性酚耗氧阻止萌发的理论，采用ＦｅＳＯ４或ＦｅＣｌ３水溶液浸种后晒干、浓Ｈ２Ｏ２溶液浸种、４０℃高温处理、贮藏在温度较高的环境下，由于能消除酚类物质的活性，或促其氧化，或强迫供氧抵消酚类物质的耗氧作用，均取得了不同程度的破眠效果。
The use of large seed Sumaimu 1, studied the use of ethephon on the seed germination. The result showed that the reason for poor germination was seed dormancy. After storage, the germination rate of seeds increased significantly. After hibernating seed peeled, higher germination rate was obtained, indicating that the dormant depressive site was in the seed shell. According to the theory of oxygen-tolerant and phenol-resistant germination in the seed shell, the seedlings were soaked in FeSO4 or FeCl3 aqueous solution, soaked in concentrated H2O2 solution and treated at 40 ° C under high temperature. Due to the elimination of phenolic compounds , Or promote its oxidation, or forced oxygen to offset the oxygen consumption of phenolic substances, have achieved varying degrees of hypnotic effect.
