| Abstract | Changes in transpiration and stomatal conductance and other characteristics of water relations, growth rate, and ABA content have been followed in short- and long-term experiments in two barley cultivars (cv. Michaelovsky and cv. Prairie) with contrasting drought resistance characteristics. The aim of this work was to reveal the importance of stomatal behavior in salt tolerance and also the involvement of ABA in its control. Salinity stress brought about a reduction in stomatal conductance in both cultivars, but the effect was initially more pronounced in the drought-tolerant cv. Prairie than in the drought-sensitive cv. Michaelovsky. The difference between the two cultivars changed with time, and later on transpiration and stomatal conductance became higher in Prairie than in Michaelovsky. In both the short and the long term, the extent of stomatal closure due to salinity correlated with the level of ABA accumulation in the leaves of the plants. Fast stomatal closure was likely to be responsible for growth resumption after an initial arrest by salt treatment and for the maintenance of extension growth later on, thus enabling its higher rate in Prairie than in Michaelovsky plants. Leaves of Prairie accumulated less toxic chloride ions, which may be the result of a lower transpiration rate observed during the first phase of salt treatment. A subsequent increase in stomatal conductance observed in Prairie is likely to ameliorate their gas exchange and maintain photosynthesis and growth. Thus, differences between the cultivars in the stomatal response to salinity changed with time, which may be why there are discrepancies in the attempts to relate stomatal conductance to salt tolerance observed in literature. |

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.
