摘  要:
通过对孔雀草(Tagetes patula L.)进行叶面施肥和遮光处理,研究了施肥和遮光对孔雀草生理指标的影响。结果表明,遮光使孔雀草叶片的丙二醛(MDA)、游离氨基酸、游离脯氨酸(Pro)含量和过氧化物酶(POD)活性显著增加;叶面施肥使孔雀草叶片中的叶绿素含量显著增加,使叶片的MDA、游离氨基酸、Pro含量下降,POD活性减弱;叶面施肥和遮光对孔雀草的生理代谢存在一定的交互效应,说明充足施肥和光照是保证孔雀草生长良好的重要因素。

摘  要:
The effects of leaf fertilization and shading on the physiological characteristics of Tagetes patula L.were analyzed.The results showed that the contents of MDA,amino acid and Pro were decreased and the POD activity was intensified under shading.The chlorophyll content was increased,and the contents of MDA,amino acid and Pro were reduced after using leaf fertilizer,while the POD activity was weakened.The leaf fertilization and shading had an interactional effect on the physiological metabolizing of T.patula.That means both of good shading and sufficient fertilizer were important growth condition for T.patula.
