【摘要】 层积处理和去除种皮处理对红松种子萌发能力及过氧化物酶的活性有明显的影响。过氧化物酶在种子的休眠机理中可能有一定意义。红松种子的粗提物除能抑制种子萌发外,还有强烈抑制过氧化物酶活性和呼吸的能力。通过纸层析和薄层层析初步鉴定出,这些物质与抑制萌发的物质并非同一物质。粗提物中至少有两种过氧化物酶的抑制物,它们具有不同的稳定性。对酶活性抑制的时间曲线有不同影响,对不同同工酶和不同生物来源的过氧化物酶表现出不同的抑制。更多还原

【Abstract】 The effect of both stratificating and decoating on germination and peroxidase acti- vity of Pinus koraiensis seeds suggest that some role might be played by peroxidase in seed dormancy.Crude extract of seed are strongly inhibiting peroxidase activity and respiration in addition to hindering seed germination.Paper and thin layer chromatog- raphic analyses have provided evidence that these activities are not attributable to the substance present in extracts which can inhibit germination.Experimental data reveal the presence of at least two kinds of peroxidases with different stability and different effects on the time course of peroxidase reaction.The inhibition on isoperoxidases and peroxidases are different from different biological sources.更多还原
