摘要
在低温胁迫条件下,采用不同浓度的稀土铈对黄瓜幼苗进行诱导处理,通过测定黄瓜幼苗在一定时期内叶绿素和脯氨酸含量的变化及其对黄瓜幼苗抗冷性的生理影响。结果表明:在冷害胁迫条件下,施用铈可以提高黄瓜幼苗的叶绿素及脯氨酸含量水平,进而影响其生理生化发育。
Different concentrations of cerium was used to cucumber seeding under low-temperature stress conditions,measuring chlorophyll and proline content changes in a given period of cucumber seedling and its physiological effect of chilling resistance of cucumber seedlings.The results showed that under the chilling stress conditions,application of cerium can improve the level of chlorophyll and proline content of cucumber seedlings,thereby affecting its physiological and biochemical development.
