四川小麦地方品种的酯酶与过氧化物酶同工酶研究

THE STUDY ON ESTERASE AND PEROXIDASE ISOZYMES IN LANDRACES OF WHEAT FROM TO SICHUAN

对181个原产于四川盆地及周缘山地的普通小麦地方品种(Triticumaestivum L.)的酯酶与过氧化物酶同工酶进行了分析研究。结果表明:不同普通小麦地方品种的幼根和幼芽中,酯酶同工酶和过氧化物酶同工酶均存在差异。E3、E5只出现在根中,E4、E10、E11、E12和E13是芽中区别于根的特征酶带;根的酯酶同工酶包括两种类型,在芽中则出现了6种类型。过氧化物酶同工酶在不同材料的根中没有差异,在芽中则变异很大,共有15种类型;根的过氧化物酶同工酶较芽显示更多的酶带,且活性更强。

The esterase and peroxidase isozymes of 181 landraces of wheat (Triticum aestivum L.)from Sichran have been studied. The results show as follows: Significant differences of either esterase or peroxidase isozymes were detected in both roots and shoots of seedling among landraces. E3,E5 are special for roots and E4,E10,E11,E12,E13,for shoots. Two kinds of isozyme patterns of esterase are involved in roots and six kinds in shoots. No variation of peroxidase isozymes appears in roots,but 15 variations arise in shoots,The roots show more zymograms and more activity than shoots in peroxideae isozyme.
