| Abstract | The correlation between desiccation tolerance and soluble sugars was investigated in seeds of a number of rice cultivars belonging to the Asian rice Oryza sativa L. They were dried or ultradried to various low moisture content and then imbibed for germination testing. Few or no changes on germination percentage and vigor index were found in Indian rice seeds even after their moisture content fell to 3.5%, indicating that Indian rice exhibited a strong desiccation tolerance. On the contrary, Japonica rice seed germination percentage rapidly decreased, after their moisture content fell to 4.5%. The capacity for desiccation tolerance in Japonica (cv. Chunjiang 15) and Indian (cv. Zhongzu 1) developing seeds increased on 23–40 and 15–25 days after pollination, respectively. Though the level of monosaccharides declined, the content of sucrose has increased during desiccation. These results suggest that desiccation tolerance might be associated with the increase in seed viability and the changes in sugar level, and that raffinose could be capable of contributing to the desiccation tolerance to ultradrying. |

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.
