EFFECTS OF ACID RAIN ON THE ALUMINUM SPECIATION AND ECOCHEMISTRY IN TEA PLANT
酸雨对茶树中铝的形态分布及生态化学影响

This paper means to clarify what effects will the acid rain has on tea plant, its aluminum speciation distribution and its ecochemistry. The results showed that the majority of aluminum exists stably as inactive aluminum in tea leaves and the accumulation of aluminum begins since the bud stage, not just in old leaves as reported by others. Study on the effect of simulated acid rain on twigs of tea plant showed that tea plant can grow well at current rain water acidity in Southwest China, i.e.pH 4.0-4.5 and will be injured only at pH 3.0. The study on the relations between aluminum and other nutrient elements in tea plant showed that the element correlating best with aluminum is phosphorus, suggesting that aluminum has close relation with phosphorus in its uptaking and transportation.
