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.

Article Synopsis
  • The study aimed to assess how different concentrations of cobalt affect nodulation, leg-haemoglobin levels, and antioxidant enzyme activities in soybean plants.
  • At a cobalt concentration of 50 mg/kg, there was a notable increase in root nodule formation, leg-haemoglobin content, and enzyme activities compared to the control group.
  • However, higher cobalt levels (100-250 mg/kg) led to a decrease in these parameters, indicating toxicity beyond a certain threshold.

The variations in antioxidant potentials and indole alkaloid content were studied in the present investigation, in two varieties (rosea and alba) of Catharanthus roseus, an important herb used in traditional as well as modern medicine, exposed to water deficit stress. The antioxidant and alkaloid profiles were estimated from root, stem, leaf, flowers and pods. The antioxidant potentials were examined in terms of non-enzymatic antioxidant molecules and activities of antioxidant enzymes.
