![عکس صفحه اول مقاله: Endogenous hormonal and enzymatic responses of Catharanthus roseus with triadimefon application under water deficits Endogenous hormonal and enzymatic responses of Catharanthus roseus with triadimefon application under water deficits](/preview/png/2784228.png)
The effect of triadimefon was investigated in a medicinal plant, Catharanthus roseus subjected to water deficit stress. The abscisic acid (ABA) level, DNA and RNA contents and activities of ATPase and protease were found varying in different parts of the plants under treatment. Drought treatment increased the ABA level more than twofold in all parts of the plants. TDM treatment to the drought stressed plants showed highest contents. In roots, stem and leaves, drought stress caused a decrease in the DNA and RNA contents when compared with control and other treatments. TDM treatment with drought increased the nucleic acid contents to the level of the control roots. The activity of ATPase and protease were increased under drought treatment and lowered due to TDM applications. This information could be useful in the field of soil water deficits reclamation efforts by using plant growth regulators. To cite this article: C.A. Jaleel et al., C. R. Biologies 331 (2008).
