| 摘 要： | 应用研制的植物低温保护剂（ＰＬＴＰＡ）喷施辣椒幼苗．生理生化测定表明，电导率，丙二醛（ＭＤＡ）含量比对照降低；ＴＴＣ还原率，脯氨酸含量，可溶性总糖和叶绿素含量比对照提高；超氧物歧化酶（ＳＯＤ），过氧化氢酶（ＣＡＴ），过氧化物酶（ＰＯＤ）等保护性酶系统的酶活性也比对照提高；根和叶ＴＴＣ还原率同步升高，电导率同步降低

| Abstract: | After spraying PLTPA (A plant low temperature protection agent invented. No of China patent 93101482.4) upon seedlings of pepper, the results show that: the enzyme activities of SOD, POD, CAT increase and reducing rate of TTC increase in the pepper seedlings, while the content of MDA and electrical conductivity rate decrease. THe contents of proline, soluble sugar and chlorophyll increase; the electrical conductivity rate decreases synchronistically and reducing rate of TTC increase synchronistically in both root and leaf. |
