Low concentration of tea (Camellia sinensis (L.) O. Kuntze) was shown to inhibit the growth of the toxic cyanobacterium Microcystis aeruginosa. The inhibition efficiency was 40% at 0.1 g dry tea/L and 90% at 0.2 g/L after a 12-day culture. All varieties of tea used in the test could inhibit Microcystis growth, in which the inhibitory effect of green ...

CaCl2 improves post-drought recovery potential in Camellia sinensis (L) O. Kuntze
Plant Cell Reports, 2010Drought stress affects the growth and productivity of the tea plant. However, the damage caused is not permanent. The present investigation studies the effect of CaCl(2) on antioxidative responses of tea during post-drought recovery. Increase in dry mass, proline and phenolic content of leaf with decrease in H(2)O(2) and lipid peroxidation and ...

Induction of synchronous secondary somatic embryogenesis in Camellia sinensis (L.) O. Kuntze
Journal of Plant Physiology, 2001Summary Nutritional effect of nitrate salts of potassium and ammonium, together with different concentrations of sulphate salts of aluminium, potassium, magnesium, and ammonium on secondary somatic embryogenesis, wereinvestigated. Nitrate salts of potassium (9.39 mmol/L) and ammonium (10.31 mmol/L) with only 1.5 mmol/L potassium sulphate produced ...

Boron re-translocation in tea (Camellia sinensis (L.) O. Kuntze) plants
Acta Physiologiae Plantarum, 2013Boron (B) re-translocation is an important factor determining tolerance to B deficiency in plants. In this work growth, B content of leaves with different ages, B partitioning between soluble and cell wall (CW) fractions, and B re-translocation were investigated in tea (Camellia sinensis (L.) O. Kuntze) plants grown hydroponically without (

Isolation and Characterization of Brassinosteroids from Leaves of Camellia sinensis (L.) O. Kuntze
Plant Growth Regulation, 2004Brassinosteroids are of ubiquitous occurrence in plants and elicit a wide spectrum of physiological responses. In our study, brassinosteroids were isolated and identified in topmost dormant leaves of tea plants. Six brassinosteriods, i.e. 6-deoxocastasterone, 24-epibrassinolide,3-dehydroteasterone, typhasterol, 3-deoxotyphasterol and 28-homodolicholide,

Influence of shade on flavonoid biosynthesis in tea (Camellia sinensis (L.) O. Kuntze)
Scientia Horticulturae, 2012Abstract Tea ( Camellia sinensis (L.) O. Kuntze) is a commercially important crop valued for its secondary metabolites. Different cultivation methods affect tea quality by altering the biosynthesis of flavonoids. Shade can effectively improve the quality of tea beverages by causing reduction of the concentration of flavonoids, the main compounds ...

An Improved Protocol for the Isolation of RNA from Roots of Tea (Camellia sinensis (L.) O. Kuntze)
Molecular Biotechnology, 2011Tea, a beverage crop, is a rich source of polyphenols and polysaccharides which greatly attribute to its importance. However, oxidation and precipitation of these compounds during nucleic acids extraction is a limitation to molecular biology and genomic studies.

Zinc Modulates Drought-Induced Biochemical Damages in Tea [Camellia sinensis (L) O Kuntze]
Journal of Agricultural and Food Chemistry, 2013Zinc (Zn) is an essential micronutrient that affects the growth and productivity of tea plant. Drought stress causes various biochemical and physiological damages in plants. The present study aims at understanding the role of Zn in modulating drought stress induced growth and biochemical damages in tea plant.

Phenolics metabolism in boron-deficient tea [Camellia sinensis(L.) O. Kuntze] plants
Acta Biologica Hungarica, 2013Modification in the metabolism of phenolic compounds under boron (B) deficiency conditions was studied in tea plants. Plants were grown from seed, treated with low B in hydroponic medium under environmentally controlled conditions for six weeks. Dry matter production and B content of plants were significantly declined under B deficiency conditions ...
