PLTPA对浸种冬小麦生理生化特性及产量的影响

Effcts of PLTPA on the Physiological Biochemical Characteristics and the Yield in Winter Wheat

用ＰＬＴＰＡ（植物低温保护剂）浸泡冬小麦种子，可使麦苗ＳＯＤ（超氧物歧化酶）、ＰＯＤ（过氧化物酶）、ＣＡＴ（过氧化氢酶）活性升高；ＭＤＡ（丙二醛）含量降低；Ｐｒｏ（脯氨酸）、可溶性总糖和叶绿素含量增加；根和叶的ＴＴＣ还原率同步增加，电导率同步降低。

The biochemical measurements showed that ,by means of soaking seeds with PLTPA, the enzyme activities of SOD,POD,CAT were increased while the content of MDA was decreased; meanwhile,the contents of proline, soluble sugar and chlorophyll were increased. Moreover,the increase of the TTC reducing ratio and the decrease of the electrical conductivity ratio were synchronous in roots and leaves.The cold hardiness and the yield of the winter wheat whose seeds were soaked with PLTPA
