| 摘 要： | 以万寿菊(Tagetes erecta L.)穴盘苗为试验材料,研究不同浓度烯效唑(S3307)及其与水杨酸(SA)复配对万寿菊穴盘苗生长和抗性生理的影响。结果表明:与ck相比,S3307及其与SA复配可降低万寿菊穴盘苗株高、冠幅,提高茎粗、根体积、根冠比(R/T)、根活力、全株干重,降低其叶片中丙二醛(MDA)含量、相对电导率,提高其叶片中叶绿素、可溶性糖、脯氨酸(Pro)的含量及过氧化物酶(POD)、超氧化物歧化酶(SOD)、苯丙氨酸解氨酶(PAL)的活性。说明S3307及其与SA复配改善了万寿菊穴盘苗的生长状况和生理代谢水平。最佳处理为10 mg/L S3307+100 mg/L SA。

| Abstract: | Used plug seedling of Marigold(Tagetes erecta L.) as the research material to investigate the effect of single S3307,S3307 and SA compound on plug seedling growth and resistance physiology of Marigold.The results showed that compared with the control,S3307 and SA compound made the height and the crown width decrease,and increased stem diameter,root volume,root cap ratio(R/T),root activity and dry weight.Decreased the malondialdehyde(MDA) contents and relative conductivity,increased the contents of chlorophy... |
