Effect of soil water content on net photosynthetic rate of Punica granatum

Abstract: The net photosynthetic rate (Pn)in Punica granatum leaves was measured under different soil water content (SWC).The results showed that the Pn and stomatal conductance (COND) declined with the decline of SWC , and the effects of SWC on COND was consistent with Pn changes .The curves of diurnal variation of Pn and COND were typical double-peaked , and both of Pn and COND decreased gradually with the decrease of SWC .It was also found that the changes of Pn was related mainly to stomatic factors when SWC was 19.14 % to 13.23 %.
