Abstract ：
Autotoxicity is widely reported in agro-ecosystems that declines the growth and yield but is seldom reported in old tea plantations. Rhizosphere soils of three tea cultivars of different ages were collected from a tea plantation in Anxi County, Fujian, China. In bioassay with test plants of lettuce (Lactuca sativa L.) and cabbage (Brassica rapa L.), the soils and soil extracts of > 9-years of planted age, were toxic to seed germination and seedlings growth of these test plants. In pot culture, the soils from > 9-years of planted age, also showed the effects similar to replanted tea seedlings. There was significant-positive correlation between the inhibition of test plants and the physiological parameters of tea leaves with the planted age of tea soils. These findings explain the reasons for the decline in the production and quality of tea from the old tea plantations.
