ABSTRACT

 

Tea [Camellia sinensis (L.) O. Kuntze] leaves contain more than 700 chemicals, among which the compounds closely related to human health are flavanoides, amino acids, vitamins (C, E and K), caffeine and polysaccharides. Tea grows in a variety of climates and it is very difficult to specify the ideal climate tea requires for good growth. Many attempts have been made, using many species, to undertake the different climatic and environmental investigations both in annual and perennial tea types for finding the ideal conditions for tea growing. The article reviews the changes in important climatic and environmental parameters in the recent past and its relations with tea growing, trends and changes in these factors over time and space (temporal and spatial variations) and discusses how different tea physiological processes are influenced by changes in environmental factors, season as well as genotypic factors/ stresses. Different climatic and environmental factors like rainfall, drought, evaporation and evapotranspiration, season, temperature, sunshine hours, day length, saturation deficit, green house gases, etc. and their relationships with tea are discussed.
