The inhabitants in and around the Park are of different ethnic group like Bodo, Garo, Rabha, etc. Keywords: and they play a vital role in conservation of flora and fauna of the Park. Climbers, Diversity, However, these people also depend on the plant resources of the area in their day Habitat, Traditional uses, to day life. The present study highlights the prevalence of climbers in the floristic composition of the area and also recorded the uses of some of the climbers by the ethnic groups of the area .A total of 88 species along with their habitat and ability recorded from the area and out of these 33 species are found to be used by the local ethnic communities of area. INTRODUCTION adequately dealt about the climbing species of The climbing plants are part of Indian flora Manas National Park .In the present work, an (Sharma and Arya, 2016). Some of the climbing attempt have been made to explore the diversity of species are often exhibit vigorous growth and fast climbers in Manas National Park (MNP) and their growing. Depending on climbing mechanism habitat specificity contribution to the vegetation climbers are classified into root climbers, hook climbers, tendril climbers, leaf or stem climbers or MATERIALS AND METHODS: twinners( Agarwal, 2013). They are used by all the Study area people either directly as folk medicine or indirectly Manas National Park occupies an area in the preparation of pharmaceuticals (Majumdar et of 500 sq. km and it is located at the foothills of the al., 2006; Manikandan et al. 2009). Thus the Bhutan Himalayas in Baksa and Chirang districts of peoples depend on climbers for several purposes Assam with a longitude 26°35'-26°50'N and like medications, non timbers forest product, food, latitude 90°45'-91°15'E. The prominent vegetation etc. In different part of India studies on diversity of types of MNP comprises of Sub-Himalayan Light climbers were undertaken by a number of workers Alluvial Semi-Evergreen forests in the northern (Gentry, 1991, Ghosh and Mukherjee, 2006; parts, East Himalayan mixed Moist and Dry Bandopadhya and Mukherjee, 2010; Jangid and Deciduous forests (the most common type), and Sharma, 2011) and opined that climbers form the Low Alluvial Savanna Woodland and Assam Valley main components of ecosystem. However, no Semi-Evergreen Alluvial Grasslands. attempt has been made as such to study the diversity The present work was conducted during the of climbing species in NE India.

DOI: 10.16943/ptinsa/2016/v82/48406 Review Article Revisiting the Status of Cultivated Plant Species Agrobiodiversity in India: An Overview ANURUDH K SINGH* 2924, Sector-23, Gurgaon, Haryana, India 122 017 (Received on 14 March 2016; Revised on 20 May 2016; Accepted on 16 June 2016) A revisit to the literature on cultivated plant species agrobiodiversity in India revealed that the floristic diversity is represented by 17,926 species of angiosperm, while Indian agriculture cultivates 811 plant species and harbours more than 900 wild relatives of the cultivated plant species distributed over 10 (+ 1) biogeographic regions of the the country, significantly higher than commonly cited in the literature. Further, it revealed the role of Indian communities in domestication to cultivation of around 215 economically important plant species, and adaption of around 600 exotic crop species. Based on new evidence, several species require inclusion and others deletion, and many need further investigations to resolve the issue on country of their origin. Cultivation of crop species in diverse natural and man-made agroecological systems for centuries has generated a huge amount of genetic diversity in a large number of crop species, maintained by the farmers in the form of landraces or farmer’s varieties, and conserved as collections/accessions in the national agricultural research system.

ABSTRACT The ethnomedical uses of Piper (胡椒 Hú Jiāo) plants as anticancer agents, in vitro cytotoxic activity of both extracts and compounds from Piper plants, and in vivo antitumor activity and mechanism of action of selected compounds are reviewed in the present paper. The genus Piper (Piperaceae) contains approximately 2000 species, of which 10 species have been used in traditional medicines to treat cancer or cancer‑like symptoms. Studies have shown that 35 extracts from 24 Piper species and 32 compounds from Piper plants possess cytotoxic activity. Amide alkaloids account for 53% of the major active principles. Among them, piplartine (piperlongumine) shows the most promise, being toxic to dozens of cancer cell lines and having excellent in vivo activity. It is worthwhile to conduct further anticancer studies both in vitro and in vivo on Piper plants and their active principles.

  • Morphoanatomical Profile of Five Species of Piper L. from Bangladesh and Its Taxonomic Significance
    Bangladesh J. Plant Taxon. 26(1): 57–68, 2019 (June) © 2019 Bangladesh Association of Plant Taxonomists MORPHOANATOMICAL PROFILE OF FIVE SPECIES OF PIPER L. FROM BANGLADESH AND ITS TAXONOMIC SIGNIFICANCE 1 2 KISHWAR JAHAN SHETHI , PARVEEN RASHID, MOMTAZ BEGUM AND M. OLIUR RAHMAN Department of Botany, University of Dhaka, Dhaka-1000, Bangladesh Keywords: Piper L.; Taxonomy; Anatomy; Stomata; Trichome; Idioblast. Abstract The present study explores detailed morphoanatomical features of five species of Piper L., viz. P. betle L., P. longum L., P. nigrum L., P. retrofractum Vahl and P. sylvaticum Roxb. Each species is supplemented by detailed updated nomenclature, vernacular names, diagnostic characters, phenology, ecology and representative specimens. Maximum number of cortical and medullary vascular bundles have been observed in P. nigrum and P. retrofractum, respectively. In contrast, minimum number of cortical and medullary vascular bundles have been found in P. sylvaticum. Glandular trichomes are found on the midrib of P. betle, P. longum, and P. sylvaticum, whereas trichomes are lacking in P. nigrum and P. retrofractum. The highest number of collateral vascular bundles have been found in P. retrofractum followed by P. nigrum, while P. betle and P. longum contain single collateral vascular bundle. P. betle can easily be distinguished from other species by its oval stem, non-glandular multicellular trichome with pointed tip, and presence of idioblasts and oil droplets. P. longum is distinct from remaining species by its diacytic stomata. Keys to the species based on morphological and anatomical characters are provided for easy identification of the studied species. Introduction The genus Piper L. (Piperaceae) consists of over 1,000 species and distributed pantropically, and the greatest diversity of Piper species occurs in the American tropics followed by Southern Asia (Jaramillo and Manos, 2001).

Abstract Piper, the pepper plants or pepper vines are an economically and ecologically important genus in the family Piperaceae. It contains about 1,000-2,000 species of shrubs, herbs, and lianas, many of which are keystone species in their native habitat. Piper species have a pan tropical distribution, and are most commonly found in the understory of lowland tropical rainforests, but can also occur in clearings and in higher elevation life zones such as cloud forests. Most Piper species are either herbaceous or vines; some grow as shrubs or almost as small trees. Many species of piper have been used for treating different diseases in many traditions. E.g P. cubeba has been used in folk medicine, herbalism as well as in the early 20th century, as a cigarette flavoring. P. darienense is used medically by the Kuna people of the Panama-Colombia border region, and elsewhere it is used to intoxicate fish which then can be easily caught. Black Pepper (P. nigrum) essential oil is sometimes used in herbalism, and Long Pepper (P. longum) is similarly employed in Ayurveda, where it was an ingredient of Triphala Guggulu and (together with Black Pepper) of Trikatu pills, used for rasayana (rejuvenating and detoxifying) purposes.
