Effect of 6-BA or KT on Photophosphorylation Activity in Wheat Flag Leaves Under Water Stress

doi:10.3321/j.issn:1000-7091.2000.03.008

Abstract

Abstract: Water stress has influence on the Hill reaction, photophosphorylation activity and the ATPase activities of the chloroplast-coupling factor in two different draught resistance wheat cultivars, Jimai 38 and Jinmai 33. After the treatment of 6-benzylaminopurine (6-BA)and Kinetin(KT)in flag leaves, Hill reaction, photophosphorylation, Mg²⁺-ATPase and Ca²⁺-ATPase activity are all improved.

Key words: 6-BA, KT, Wheat, Flag leaves, Water stress, Photophosphorylation
