Abstract: This work was carried out in a period that spans the rainy and dry seasons of 2010 – 2011. In times past, Anambra State was rich in chains of productive watershed, saturated with luxuriant plant species. This however is now history owing to steadily increasing, degradatory anthropogenic influences. Ignorance and crass indifference on the indispensability of plant resources to man’s survival in tropical Africa has also resulted in very poor biodiversity of our watersheds. Amawbia watershed is not an exception. With the assistance of a field taxonomist and relevant texts, tree, climber, shrub, grass and forb species were firstly identified and recorded for sampled sites (sites A – E). Unlike productive watersheds, the dominant species encountered in this watershed were grasses and forbs. Dominant individual plants include: Heivea brasiliensis, Senna siamea, Napoleana imperialis, Dactyledenia barteri, Pentaclethra macrophyla, (Trees); Gongronema latifolium, Dioscorea dumentorum, Telfeiria occidentalis, Smilax anceps, Cissus aralioides (Climbers); Olax viridis, Mimosa invisa, Bambusa vulgaris, Vernonia amygdalina, Sarcocephalum laxiflora (Shrubs); Zea mays, Panicum maxima, Imperata cylindrica, Sporobolus pyramidalis, Andropogon tectorum (Grass); Amaranthus viridis, Ageratum conyzoides, Sida acuta, Gomphrena celosoides, Ocimum basilicum (Forbs). Most of these species are not very important in terms of economic relevance.

Abstract: While an array of plants has long been used for the preparation of medicines, tea plants can be used for disease medication since they have been reported to possess anti-bacterial attributes. Present study emphasized on the assessment of antimicrobial activity of tea against Bacillus spp. (SkB01), E. coli (SkE01), Klebsiella spp. (SkK01), Pseudomonas spp. (SkP01), Salmonella spp. (SkS01), Vibrio spp. (SkV01). Oolong tea and green tea were used to determine the antimicrobial activity employing minimal inhibitory concentration (MIC) methods. The results clearly illustrated interesting antimicrobial potentials of both experimented teas against the tested microorganisms. Oolong tea exhibited the anti- bacterial activity against E. coli (SkE01), Klebsiella spp. (SkK01), Pseudomonas spp. (SkP01) and Salmonella spp. (SkS01). As well, green tea exhibited the anti-bacterial activity against Bacillus spp. (SkB01) and Vibrio spp. (SkV01). The in vitro anti-bacterial activity of oolong tea and green tea against the bacterial pathogens revealed most of the tea plants to be effective against the growth and survival of the pathogenic bacteria.

Abstract: The present investigation has been concentrated on the establishment of an efficacious method for in vitro regeneration of a Musa cultivar Gopi of Tripura. Focus has been greatly anchored to the sterilization procedure for assuring successful aseptic culture establishment of this cultivar. The culture protocol for shoot induction and proliferation comprised of four different treatments in basal MS medium fortified with 6-Benzylaminopurine of varying concentrations. The optimum response was encountered in the treatment of BAP in MS medium at concentration of 8mg l-1 for shoot bud induction and multiplication. Subsequent shoot growth and multiplication was achieved through repeated subcultures in media containing lower concentration (4 mg l-1). Root initiation was stimulated and brought about by treatments with two different concentrations of Indole butyric acid. The best rooting was manifested in treatment with IBA at concentration of 2mg l-1. The present study is an approach towards successful establishment of a simple and rapid clonal propagation of a potent Musa cultivar Gopi having traditional and commercial value from this region of Tripura, North-east India.
