Shoot epicatechin and epigallocatechin contents respond to water stress in tea [Camellia sinensis (L.) O. Kuntze].
An experiment was conducted to determine the association of tea catechins to water stress in tea, with the objective of determining their suitability as indicators for predicting drought tolerance in tea (Camellia sinensis). The study consisted of six tea clones (BBK 35, TRFK 6/8, TRFK 76/1, TRFK 395/2, TRFK 31/30, and TRFK 311/287) and four levels of soil water content (38, 30, 22, and 14% v/v...
متن کاملDiverse Colletotrichum species cause anthracnose of tea plants (Camellia sinensis (L.) O. Kuntze) in China
Anthracnose caused by Colletotrichum is one of the most severe diseases that can afflict Camellia sinensis. However, research on the diversity and geographical distribution of Colletotrichum in China remain limited. In this study, 106 Colletotrichum isolates were collected from diseased leaves of Ca. sinensis cultivated in the 15 main tea production provinces in China. Multi-locus phylogenetic ...
متن کاملSubcellular Localization of Galloylated Catechins in Tea Plants [Camellia sinensis (L.) O. Kuntze] Assessed via Immunohistochemistry
Galloylated catechins, as the main secondary metabolites in the tea plant, including (-)-epigallocatechin-3-gallate and (-)-epicatechin-3-gallate, comprise approximately three-quarters of all the tea plant catechins and have stronger effects than non-galloylated catechins, both on the product quality in tea processing and the pharmacological efficacy to human beings. The subcellular localizatio...
متن کاملChanges in Antioxidative Responses to Low Temperature in Tea[Camellia sinensis (L) O. Kuntze] Cultivars
Effect of low temperature stress treatment in five selected clones of Camellia sinensis (T-17, TV-19, TV-25, TV-29, TV-30) was found to be significant. Guaiacol Peroxidase (GPX) decreased with decreasing temperature. PPO decreased with decreasing temperature showing highest activities at 20°C in all clones. CAT activit ies decreased in T-17, TV29, and TV-30 with decrease in temperature with exc...
متن کاملDifferential Proteomic Analysis of Chilling Stress Responses in Tea Plant [Camellia sinensis (L.) O. Kuntze]
Low temperature is one of the serious environmental stresses affecting plant growth and agricultural production. It not only inhibits metabolic reactions but also causes osmotic, oxidative, and other damages [1]. Chilling temperatures that range from 0 to 12°C are common during the growing season and can substantially decrease plant productivity [2]. Plants respond and acclimate to chilling str...
