The variation of chlorophyllase activity in tea plant（Camellia Sinensis）was investigated. The results showed that the diurnal variation of chlorophyllase activity decreased gradually from 7:00 to 16:00, and then showed an upward tendency from 16:00 to 19:00. The chlorophyllase activity diversity also existed in various seasons and leaf tenderness. The activity of chlorophyllase in the shoots of tea plant was highest in spring and lowest in autumn, and it took second place in summer. In the different growth position of tea plant, the chlorophyllase activity decreased with an order of bud > the first leaf > the second leaf > the third leaf > the old leaf > the young stem. During the fresh leaf spreading process of 6-hour treatment, the activity of chlorophyllase declined at the beginning and increased greatly later. The activity of chlorophyllase in eight different cultivars of Camellia Sinensis was determined. The results indicated that the sequence of the chlorophyllase activity among different cultivars from high to low was Fuyunliuhao>Fudingdahao>Fudingdahao>Echa1>Pingyangtezao>Wuniuzao>Yingshuang>Longjing 43. Further than that, the influence of overhead shading in tea garden on the chlorophyllase activity was studied. The result suggested that the activity of chlorophyllase both decreased after the treatment of 60% shading rate and 80% shading rate.
