【摘要】 以海洋皇马铃型银杏种子(GingkobilobaL.)为研究对象,研究了漂白粉液漂洗法、SO2熏蒸法、石灰水浸泡法、阳光曝晒法、热风干燥法等漂白方法对银杏种子贮藏期间硬化的影响;对贮藏期间呼吸强度、细胞膜透性、α-淀粉酶活性、β-淀粉酶活性等指标进行了测定,对漂白处理的抑制机理进行了探讨。结果表明:SO2熏蒸法是银杏种子较为合适的贮前漂白处理方法,该法对呼吸强度、细胞膜透性、α-淀粉酶活性、β-淀粉酶活性等有较强的抑制作用。更多还原

【Abstract】 The material in this experiment was the seeds of WTGinkgo biloba L. The ginkgo seeds bleached with different methods （sunshine, lime water, bleaching powder, hot air, and SO₂）, and then stored at ambient temperature were used to study the effects of bleaching methods on hardening. Respiration intensities, α-mylase and β-mylase activities, cell membrane permeability were measured. The experiment showed that bleaching with SO₂ resulted in an optimal effect on hardening.更多还原
