Abstract:The experiment studied the net photosynthetic response of tea leaves to ecological factors in Tieguanyin cultivars.The tea tree was planted in pot.The results showed that net photosynthetic rate ( Pn )of tea leaves increased quickly with increasing photosynthetic active radiation( PAR ),the light compensation point of photosynthesis( LCPΔ )and light sturation point of photosynthesis( LSPΔ )in tea leaves were 50~110μmol/m 2·s and 1800~2000μmol/m 2·s respectively.The LCPΔ and LSPΔ varied wit...
