Abstract: Hydroponic cultivation was used to study the effects of long-term treatment with different levels of Mn on accumulation of Mn and physiological active substance in two tea cultivars. The result indicated that Fuding cultivars shows stress phenomenon of Mn after long-term treated by Mn addition treatment. while that of Zhu yeqi cultivar is not. Mn concentration in tea leaves of Zhu yeqi cultivar is higher than that of Fuding during growing 50 days and 176 days respectively. Except the A treatment the Mn concentration in other treatment, the tea plant leaves of Fuding cultivar are higher than that of Zhu yeqi cultivar in 143 days. At the middle stage, some leaves of Fuding cultivar show the phenomenon of Mn stress, chlorophyll content in tea leaves decrease, young leaves become yellow, old leaves become brown. The change of Superoxide Dismutase (SOD), peroxidase (POD), polyphenoloxidase (PPO) and Maleic Dialdehyde (MDA) activity shows tea plants are in the situation of Mn stress. However, Zhu yeqi cultivar shows greater ability of anti-Mn stress than that of Fuding cultivar. This indicated that the ability of anti-Mn stress for tea pant showed relationship with tea plant cultivar.

Key words: Mn, tea plant, solution cultivate, stress
