| Abstract | We previously reported a partial agricultural and amplified fragment length polymorphism (AFLP) characterization of two new pineapple somaclones (P3R5 and Dwarf) derived from in vitro culture of the donor cv. Red Spanish Pinar. Both somaclonal variants showed different AFLP banding patterns compared to the donor cultivar, although they were separated by less than 0.09 U of genetic distance. The present report shows data of various indicators of morphology and physiology of P3R5 and Dwarf D leaves. The stoma diameter, number of stomata per square millimiter, diameter of leaf vascular tissue, thickness of the leaf aquiferous parenchyma, and thickness of the leaf photosynthetic parenchyma were measured. The photosynthetic rate, the transpiration rate, the water use efficiency, the internal leaf CO$_{2}$ concentration, and the chlorophyll pigment contents were recorded as well. Between the somaclonal variant P3R5 and the donor genotype, statistically significant differences were recorded in all indicators with the exception of the stoma diameter and the photosynthetic rate. Comparing the somaclonal variant Dwarf and the cv. Red Spanish Pinar (donor), statistically significant differences were also recorded in all parameters except in the stoma diameter and in the transpiration rate. This investigation was performed to demonstrate that small changes in the pineapple DNA may result in relevant phenotypic modifications. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
