The respiration of plucked tea leaves was investigated. The respiratory rate of leaves was measured by absorbing the discharged CO<SUB>2</SUB> into an alkali solution. It was more vigorous at higher temperature (35°C.), at the upper leaves of shoot, as well as at the younger period of growth of shoot. It reached the max. value 8-12 hours after plucking of leaves, thence declined and maintained the half value of the max. for a while, and after 42 hours, it dropped again and settled on a lower constant level.<BR>During the storage, the deterioration of the quality of tea leaves was remarkable, especially at higher temperature, for long period, and with the younger part of leaves.
