| Abstract | This study has analyzed the response of Ethiopian mustard (Brassica carinata A. Braun) to induced drought stress and subsequent rehydration in terms of plant growth, water status, chlorophyll concentration, chlorophyll fluorescence (F $_{V}$ /F $_{M}$), net photosynthetic rate (Pn), transpiration rate (E), and stomatal conductance (g $_{s}$). Potted plants were subjected to drought stress for 15 days and then to a daily irrigation for 5 days with 100 % field capacity (FC), and then extent of possible loss due to stress and gain due to rehydration was analyzed. The control population was maintained on normal watering schedule with 100 % FC. Drought stress reduced the growth rate of root and shoot, number of leaves, dimensions (width, length, and area) of leaves, and the biomass accumulation in different plant parts. With increase in drought stress, the relative water content, chlorophyll content, F $_{V}$ /F $_{M}$, Pn, E, and g $_{s}$ were reduced. After rehydration, a complete or partial recovery was seen for all the parameters studied. On the whole, B. carinata employs a morpho-physiological drought-avoidance strategy. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
