Changes in thearubigin fractions and theaflavin levels due to variations in processing conditions and their influence on black tea liquor brightness and total colour
(Elsevier, 2004-03-30)
Increase in coarser plucking standards significantly (P< 0.05) depressed levels of theaflavin
(TF; μmol/g), total colour and brightness (spectrophotometer) of black tea. But total
thearubigins (TR) TRSI, TRSII and ...
Influence of region of production on clonal black tea chemical characteristics
(2008-05-01)
Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and
Malawi, shows variations in both chemical composition and quality. Whereas it is possible to
produce black teas with similar ...
The use of green tea (Camellia sinensis) leaf flavan-3-ol composition in predicting plain black tea quality potential
(Elsevier, 2007-12-13)
Reliable and quantifiable green leaf parameters for predicting black tea quality potential of
tea bushes at the single bush stage are necessary to shorten tea breeding and clonal
selection programmes. Green leaf ...
Comparative responses in plain black tea quality parameters of different tea clones to fermentation temperature and duration
(Elsevier, 2001-02-01)
The amounts of black tea theaflavins, brightness, and sensory evaluations varied with clones in the order clone 6/8>SC12/28>S15/10, while thearubigins and total colour changed in the reverse order. The rates of change of ...
Responses of clonal tea to location of production and plucking intervals
(Elsevier, 2009-07-01)
Tea is cultivated in diverse environments causing yield and quality differences in its beverages. To maximise yields and quality, agronomic practices should be optimised. But agronomic recommendations are uniform in different ...
NPK (S) fertilizer use in commercially cultivated clone BBK 35 in different tea growing regions of Kenya: I. Experimental design and initial soil chemical properties.
(Tea Research Foundation of Kenya, 2008)
An experiment was set up in five sites by superimposing on commercially grown plantations consisting of one popular tea cultivar, clone BBK 35 at Timbilil estate, Kericho; Changoi Estate, lower Kericho; Magura-Kipkebe ...
NPK (S) fertilizer use in commercially cultivated clone BBK 35 in different tea growing regions of Kenya: II. Effects of nitrogen rates and plucking intervals on soil chemical …
(Tea Research Foundation of Kenya, 2008)
One commercially and widely grown tea cultivar, clone BBK 35 was evaluated for changes in soil chemical properties at different N-fertilizer rates and plucking rounds in five different localities in Kenya. The soils in all ...
Long term fertilizer use on high yielding clone S15/10: Tea yields
(International society of tea science, 2008)
High production of young tender shoots of Camellia sinensis L. O. Kuntze to make tea beverages leads to soil nutrients depletion through harvested crop and leaching. The production can be sustained by replenishing the lost ...
Productivity and nitrogen use of tea plantations in relation to age and genotype
(Elsevier, 2008-07-11)
Lack of science-based knowledge on responses of tea bushes to nitrogen (N) in ageing tea plantations hampers the development of ecologically sound and economically profitable N-management strategies. It is hypothesized ...
Effects of water stress on growth and water relations of young grafted tea.
(Tea Research Foundation of Kenya, 2009)
The effects of soil water stress on some physiological parameters and dry matter partitioning (dm) were studied in grafted tea plants (Camellia sinensis L.) grown in containers and subjected to adequate and reduced water ...
