摘要/Abstract

Abstract: Diurnal changes in leave photosynthesis at the late development stage of winter wheat were examined.The results indicated that the photosynthetic rate was parallelly changed with,but not totally dependent on the variation of st omatic conductance.At 10∶00 am, the photosynthetic rate reached its highest le ve l,then gradually decreased along with the stomatic conductance.Before 12∶00 am, the decrease in photosynthetic rate was mainly caused by stomatic limitation s.Following it,stomatic limitations (Ls) were decreased,and the intercellu ler CO₂ concentration (Ci) was increased.Inhibition of photosynthesis,in cluding the decrease of leaf photosynthetic capacity (J_max) and Rubisco ca rboxy lic activity and efficiency (A/Ci) was mainly resulted from nonstomatic limitations,not stomatic limitations.
