Comparison of antioxidant enzymes activities between sleep buds and activated pulmonary in tea clone Iran 100 cultivar

The growth of the shoots is one of the most important physiological stages that determines the final performance of the tea plant. The number of shoots depends on theactivity and growth of the lateral bud. In some tea plant cultivars, the number of shoots per unit area is limited by creating a sleep bud phenomenon, which increases the distance between harvesting leaves, so, decreasing the yield. Sleep sprout like other environmental stresses activates a series of plant defense responses. One of these responses is the activation of the enzyme system. In this study, we are discussing the molecular mechanism of the sleep mode of bud in tea plant, comparing the biochemical structure of sleep state and activated bud as well as attempting to break the sleep state artificially in the clone 100 cultivar, the promising tea plant in Iran. Enzyme activities were measured in order to achieve peroxidase enzymes, ascorbate peroxidase and catalase amount in the plant. The results showed that the activity of these enzymes was higher in the Banji bud compared to the active bud in the cultivar.
