| Abstract | Plant architecture is one of the determinants on canopy light absorption and photosynthesis. The quantification of architecture is rather difficult for some specific crops, i.e. tobacco. In this study, a field experiment was carried out to study the architecture of two tobacco cultivars (Y87 and K326) in situ by the combination of 3-D laser scanning and digitizing methods at the squaring stage. Static 3-D model of tobacco plant was built based on leaf surface geometry (collected by 3-D scanning) and leaf outline (obtained by digitizing in situ). The parameters describing plant architecture were derived and light absorption and potential photosynthesis of individual leaves as well as plants were calculated utilizing 3-D modeling. The validation results indicated that the canopy light distribution can be computed rather accurately comparing with the field measurements. Simulation results showed light absorption and potential photosynthesis of Y87 were lower than those of K326, partly because the leaf area of individual Y87 plants was smaller than that of K326. |

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.
