Abstract
Under natural conditions,we studied the photosynthesis of maize(Zea mays L.) in its whole life treated with different intensities,i.e.,0 (CK),0.01(R1) and 0.015 J·m~(-2)·s~(-1)(R2) of ultraviolet-B(UV-B) radiation.The results showed that enhanced UV-B radiation reduced the photosynthetic pigment(including chlorophyll a,chlorophyll b,total chlorophyll and carotenoid) contents,Hill reaction activity,stamotal conductance,and net photosynthetic rate of maize seedling's leaf,but had no effects on the photosynthesis of fully grown plant.
