Transpiration characteristics of tea tree

Abstract

Abstract: The transpiration rate and stomatal conductance of tea tree are varied with its cultivars and leaf position.Cultivars with stronger drought resistance have a lower stomatal conductance, and fish leaf has a similar or higher transpiration rate and stomatal conductance than true leaf.The transpiratidn rate of tea leaf is highest in summer and autumn, second in spring, and lowest in winter.On clear days, the diurnal fluctuation of transpiration rate and stomatal conductance of tea leaves shows a single peak, being highest before and after noon, and related significantly to photon flux density, leaf temperature and vapor pressure deficiency.Photon flux density has a significant effect on transpiration rate and stomatal conductance.

Key words: Tea tree, Transpiration rate, Stomatal conductance, Ecological factor, global change, soil microorganism, field manipulative experiment, carbon and nitrogen cycle.
