研究了浙贝母低温解除休眠过程中过氧化物酶和酸性磷酸酶的活性变化。结果表明,鳞片近轴面表皮的过氧化物酶活性大大高于鳞片内部贮备组织的过氧化物酶活性,而和芽的酶活性接近。鳞片内部贮备组织的酸性磷酸酶活性在低温解除休眠的后期快速上升。

Changes in the activities of peroxidase and acid phosphatase in Fritillaria thunbergii Miq. were studied during the process of relieving dormancy at low temperature. Results showed teat the peroxidase activity of adaxial epiderm were much higher than that of the inner store tissue in the scale,but approached that of the bud. The acid phosphatase activity of the inner store tissue in scale increased quickly at the late stage of relieving dormancy.
