Item Open Access A Cytogenetic Study of Seven Tea Clones [Camellia sinensis (L.) 0. Kuntze|(University of North Bengal, 2009-03) Roy, SC; Chakraborty, BNKaryotype analyses in seven cultivated clones (cv. T78, T383, TV30, HV39, TecnAli17/1/54, TV29, und UPASI-26) of tea (Camellia sinensis) are investigated for their cytogenetic characterization. Karyotypes of the chromosomes (2n = 30) were grouped arbitrarily on the basis of their length and position of the centromere into four types (A-D). Centromeric index (F %). total centromeric index (TF %), disparity index (DI) and total haploid chromosome length (TCL) were calculated. Chromosomes were found to be short to medium in size varied in length from 1.24 μm to 4.20 μm. Karyotypes were gradate and asymmetric in nature with median to nearly submedium chromosome. On the basis karyotype analysis, varietal distinction can be marked to some extent.Item Open Access Efficacy of anthocyanin in production of remedial tea(University of North Bengal, 2015-03) Labar, Reha; Sen, ArnabTea is consumed as a medicinal beverage from centuries, as the medicinal component includes polyphenols, caffeine, and amino acids. Apart from that it also contains flavonoids; compounds reported to have antioxidant properties with many beneficial effects. Anthocyanins belonging to the flavonoid group are naturally occurring compounds that imparts colour to fruits, vegetables and plants. Apart from that it has an array of health promoting benefits. This article has been reviewed to highlight the importance of anthocyanin as well as to motivate research in exploring tea varieties with abundant anthocyanin so that consumption of anthocyanin rich tea or beverage and also use of natural dye made using anthocyanin would replace harmful effects of chemical drugs and also improve country's economy by flourishing the tea industry with increased consumption.Item Open Access Generation and characterization of expressed sequence tags of tea (Camellia sinensis L (O) kuntze)(University of North Bengal, 2011) Das, Akan; Saha, DipanwitaItem Open Access Induction of resistance in tea (Camellia sinensis (L.)
