Melatonin, GlutathioneAbstract
This current study was conducted an agricultural nursery in the Al-Muqdadiya district which is in the north of Baqubah, the center of Diyala governorate and lies 90 km north east of the capital Baghdad. The experiment was done in autumn on capsicum annuum L, Hybrid Barbarian F1, the Indian origin. It aimed to investigate the impact of treatment with melatonin and glutathione on the Vegetative features of capsicum annuum L grown under polluted conditions with cadmium. The experiment was carried out according to Randomized Complete Block Design (R.C.B.D.) in three replicates. It includes three transactions, these were cadmium which was added to soil with the two concentrations 0 and 15 mg.kg soil-1, whereas melatonin and glutathione were added spreading on the leaves with the concentrations 0,50, and 100 mg.l-1. The results showed a significant decrement in plant height, number of leaves, and leaf area as a result of treating the agricultural soil with cadmium at a concentration of 15 mg.kg soil-1, compared to the treatment without the addition of cadmium, i.e. the control treatment. It was also shown from the results obtained that there was a significant increase in all the studied traits as a result of spraying the plants with melatonin and that the highest average for each of the plant height, number of leaves, and leaf area was obtained as a result of spraying the plants with melatonin at a concentration of 100 mg. l -1. Significant increases were also obtained in all the traits under study as a result of spraying plants with glutathione at a concentration of 100 mg.l-1.
