Drought and drought with triazoles induced changes on pigment composition and biochemical constituents of Zea mays L. (Maize)

Publication date: Available online 14 April 2015 Source:Applied & Translational Genomics Author(s): Mahalingam Rajasekar , Paramasivam Manivannan In the present study pot culture experiment was conducted to estimate the ameliorating effect of triazoles, namely triadimefon (TDM), paclobutrazol (PBZ) and hexaconazole (HEX) on drought stress, pigment composition and biochemical constituents of Zea mays L. (Maize) belongs to the family poaceae. From 30days after sowing (DAS), the plants were subjected to 4days interval drought (DID) stress and drought stress with TDM at 15mgl−1, PBZ at 15mgl−1 and HEX at 10mgl−1 and one day interval irrigation was kept as control. The plant samples were collected on 40, 50 and 60 DAS, and separated into root, stem and leaf for estimating the photosynthetic pigments and biochemical constituents. Drought and drought with Triazole compounds treatment increased biochemical constituents like amino acid (AA), proline (PRO) content, whereas decreased the pigment contents like chlorophyll and carotenoid when compared to control. The triazole treatment mitigated the adverse effects of drought stress by increasing the biochemical potentials and thereby paved the way for overcoming drought stress in maize plants.
