| Abstract | Drought stress is one of the abiotic stresses and it may alter plant growth, metabolism and yield. The present study aims to analyze the growth, chlorophyll pigments, osmotic adjustment and antioxidative enzymes activity in Panicum sumatrense under drought stress. The control was irrigated daily and treated plants were irrigated at 4-, 7-, 10-, 13-day intervals. Later, they were irrigated at 3-day interval up to 70 DAS. The root and leaf samples were collected on 30 DAS, 50 DAS and 70 DAS and used for analysis. The root length increased gradually in all drought treatments at all growth stages of P. sumatrense. The chlorophyll pigments and plant height showed a reduction in 13 DID treatment when compared to all treatment. Compatible solutes like proline, glycine betaine and free amino acid increased in all drought treatment when compared to control at 70 DAS. Furthermore, stress treatment caused an increase in activity of antioxidant enzymes like superoxide dismutase, catalase and peroxidase. Panicum sumatrense possess many growth and physiological drought tolerance characters which can be used in future breeding program. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
