On Pb-contaminated soil, the use of organic fertilizer could stimulate the output, the chlorophyll content, the protein content and activity of enzyme of potherb mustard.

在Pb污染的土壤上，施用有机肥能提高雪里蕻产量、叶绿素含量、蛋白质含量和酶活性。

Treatments with 20μmolL^(-1) CoCl2 and 20μmolL^(-1) AVG did not influence the contents of putrescine, spemidine, spermine, chlorophyll, and the production rate of reactive oxygen species. However, after 12h heat stress of 45℃, treatments significantly promoted the above values.

但经45℃高温胁迫12h后，20μmolL^(-1) CoCl2与20μmolL^(-1) AVG溶液处理显著提高了上述3种多胺的含量，减缓了抗氧化酶活性的下降，对活性氧水平及脂质过氧化水平的增加也起到了有效的抑制作用，这些改变可能对叶绿素降解的减少及膜稳定指数下降的减轻发挥着重要的作用。
