Abstract: With 8901-11 and 4185, two field-grown winter wheat varieties, the changing regulation of the effect of different zinc fertilization levels on the activity of carbonic anhydrase ( CA) in leaves of winter wheat was determined.The activity of CA in top function leaves continually increased after double ridge stage and reached the maximum at flowering stage, then decreased.T he activity of CA in flag leaf and the 3rd leaf from top alLreached the maximum values at the 7th or 14th day after fulLexpansion, then decreased gradually, but fluctuations stilLoccurred with growing stages and ecologicaLconditions.T he highest value of CA activity in flag leaf was higher compared with that in the third leaf from top.The activity of CA in the treatments with zinc fer-tilization is higher than that without zinc fertilization for both varieties, and there were smalLdifferences in the activities of CA for the three zinc levels in the third leaf from top and the flag leaf.
