Fruit, leaves and tender shoots are used as food system and medicine from time immemorial. It is dioecious plant and mainly distributed throughout North India (Plains), extending to Assam and East Bengal, generally propagated by stem cuttings or root suckers. The current research is focused at the ethno-medicinal plant's phyto-chemical and in vitro antioxidant efficiency. The existence of alkaloids, triterpenoids, phytosterols, flavonoids, saponins, amino acids and proteins has been shown by phyto-chemical screening. Antioxidant performance was measured through radical scavenging techniques, using ascorbic acid (standard), 1,1-diphenyl-2-picrylhydrazyl and hydrogen peroxide. The methanol extract was showing antioxidant capacity. Thus, this herb can be used as a potential resource for drug research.

Wehner Department of Horticultural Science North Carolina State University Raleigh, North Carolina 27695-7609, USA ABSTRACT Trichosanthes is the largest genus of the family Cucurbitaceae. Its center of diversity exists in southern and eastern Asia from India to Taiwan, The Philippines, Japan, and Australia, Fiji, and Pacific Islands. Two species, T. cucumerina (snake gourd) and T. dioica (pointed gourd), are widely cultivated in tropical regions, mainly for the culinary use of their immature fruit. The fruit of these two species are good sources of minerals and dietary fiber. Despite their economic importance and nutritive values, not much effort has been invested toward genetic improvement of these crops. Only recently efforts have been directed toward systematic improvement strategies of these crops in India. Horticultural Reviews, Volume 41, First Edition. Edited by Jules Janick.

The user has requested enhancement of the downloaded file. CHAPTER 2 Classification of Vegetable Crops There are about 10,000 plant species that are used as vegetables the world over. Of these, about fifty plant species or so are commercially important. It is therefore, important to classify vegetables into groups or classes to better understand or discuss them. Vegetables that share some characteristics are grouped together. There are different ways of classifying vegetable crops but none of these methods would satisfy completely the different groups like farmers, consumers, academics etc. Broadly there are five methods of classifying vegetables. These include; 1. Botanical classification 2. Classification based on hardiness or temperature 3. Classification based on plant part used 4. Classification based on culture 5. Classification based on life cycle 2.1. BOTANICAL CLASSIFICATION This is the only method of classifying crop plants, which is universally accepted. Linnaeus, a renowned taxonomist was the first to give binomial classification in plants and animals.

  • Trichosanthes (Cucurbitaceae) Hugo J De Boer1*, Hanno Schaefer2, Mats Thulin3 and Susanne S Renner4
    de Boer et al. BMC Evolutionary Biology 2012, 12:108 http://www.biomedcentral.com/1471-2148/12/108 RESEARCH ARTICLE Open Access Evolution and loss of long-fringed petals: a case study using a dated phylogeny of the snake gourds, Trichosanthes (Cucurbitaceae) Hugo J de Boer1*, Hanno Schaefer2, Mats Thulin3 and Susanne S Renner4 Abstract Background: The Cucurbitaceae genus Trichosanthes comprises 90–100 species that occur from India to Japan and southeast to Australia and Fiji. Most species have large white or pale yellow petals with conspicuously fringed margins, the fringes sometimes several cm long. Pollination is usually by hawkmoths. Previous molecular data for a small number of species suggested that a monophyletic Trichosanthes might include the Asian genera Gymnopetalum (four species, lacking long petal fringes) and Hodgsonia (two species with petals fringed). Here we test these groups’ relationships using a species sampling of c. 60% and 4759 nucleotides of nuclear and plastid DNA. To infer the time and direction of the geographic expansion of the Trichosanthes clade we employ molecular clock dating and statistical biogeographic reconstruction, and we also address the gain or loss of petal fringes. Results: Trichosanthes is monophyletic as long as it includes Gymnopetalum, which itself is polyphyletic. The closest relative of Trichosanthes appears to be the sponge gourds, Luffa, while Hodgsonia is more distantly related. Of six morphology-based sections in Trichosanthes with more than one species, three are supported by the molecular results; two new sections appear warranted. Molecular dating and biogeographic analyses suggest an Oligocene origin of Trichosanthes in Eurasia or East Asia, followed by diversification and spread throughout the Malesian biogeographic region and into the Australian continent.

Immature fruits at green stage are commonly consumed as a vegetable after cooking. It is extensively cultivated during summer season in tropical and subtropical regions but potential to grow in temperate regions due to its wide range of phenotypic and genotypic variability. The exploitation of these variations might be the basis for subsequent improvement of this crop. The purpose of this study was to investigate morphological and ecological characteristics for the selection of suitable genotypes for cultiva- tion in Japan. Mature vines of 33 (24 female and 9 male) pointed gourd accessions have been collected from Bangladesh and cultivated in glasshouse as well as open field at Hakozaki, Kyushu University in northern Kyushu, Japan. Among these genotypes PGF01, PGF02, PGF04, PGF08 and PGF17 have been selected for early flowering, maximum flesh content, fruit weight, fruit yield and fruit set rate, respectively.

    ISSN 0258-7122 Bangladesh J. Agril. Res. 35(1) : 135-142, March 2010 IN VITRO CULTURE OF POINTED GOURD (Trichosanthes dioica Roxb.) M. A. MALEK1, D. KHANAM2, M. KHATUN3 M. H. MOLLA4 AND M. A. MANNAN4 Abstract An experiment was conducted to study the in vitro culture of pointed gourd. Cotyledon rescued from physiologically matured seeds (PMS) and immatured seeds (IMS) of pointed gourd were used as explants. Cotyledon excised from PMS responded very well in all culture conditions. Plant regenerated from cotyledon of PMS ranged from 38 to 96% in different hormonal formulations of culture media. Highest percentage of shoot regeneration was observed in MS + 1.0 mg/l BAP and lowest in MS + 2.5 mg/l BAP. No plant regeneration was observed in cotyledon from immatured seeds. The highest percentage of root induction (99%) was achieved in half MS medium supplemented with 0.5 mg/l NAA. The regenerated plantlets were successfully established in earthen pot. Keywords: Cotyledon, in vitro, pointed gourd. Introduction Pointed gourd (Trichosanthes dioica Roxb.) is an under exploited important summer vegetables in Bangladesh (Rashid, 1993).
