| Abstract | Influence of climatic conditions (total precipitation and sunshine duration) on the dynamics of chlorophyll photosynthetic potential (CPSP) and its relation to productivity of crop stands was studied with long- and short-stalked cultivars of winter wheat (Triticum aestivum L.). The reduction of the total exposure time to solar photosynthetically active radiation by 100 h per growing season (humid year) was shown to decrease CPSP by a factor of 1.3 and 1.5 in long-stalked and short-stalked cultivars, respectively. The decrease was mainly related to the suppression of biomass production, one of the main constituents of photosynthetic potential. Retardation of growth processes was manifested in a twofold decrease in the shoot number per m$^{2}$ on average; furthermore, morphological stages were delayed during early development. Suppression of growth processes by the shortened sunshine time was not compensated for by a 30% increase in specific chlorophyll content (as distinct from shade leaves), the other component of CPSP. It was shown that growth conditions have an effect on the correlation coefficient between CPSP and productivity. |

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.
